The BBC micro:bit is a pocket-sized codeable computer with motion detection, a built-in compass, LED display, and Bluetooth technology built in.

It measures 4cm by 5cm, is available in a range of colours, and designed to be fun and easy to use. It can be coded with something simple in seconds – like lighting up its LEDs or displaying a pattern – with no prior knowledge of computing.

It also connects to other devices, sensors, kits and objects, and is a companion to Arduino, Galileo, Kano, littleBits and Raspberry Pi, acting as a spring board to more complex learning.

Each element is completely programmable via easy-to-use software on a dedicated website that can be accessed from a PC, tablet or mobile.

10-bit ADC (SPI) MCP3008 - 8 Channel (10-bit ADC 8 Channel)

The Raspberry Pi is a great computer but there's just one thing that most hardware hackers will find missing: a few inputs for connecting analog sensors. This is where the MCP3008 chip comes in handy, with eight 10-bit channels accessible over SPI. Thanks to the Raspberry Pi's SPI interfaces and its two 'Chip Select' pins available off of the main GPIO connector, the problem is solved.

Features

  • 10-bit resolution
  • ± 1 LSB max DNL
  • ± 1 LSB max INL
  • 8 input channels
  • Analog inputs programmable as single-ended or pseudo-differential pairs
  • On-chip sample and hold
  • SPI serial interface (modes 0,0 and 1,1)
  • Single supply operation: 2.7V - 5.5V
  • 200 ksps max. sampling rate at VDD=5V
  • 75 ksps max. sampling rate at VDD=2.7V
  • Low power CMOS technology
  • 5 nA typical standby current, 2 µA max.
  • 500 µA max. active current at 5V
  • Industrial temp range: -40°C to +85°C

Applications

  • Sensor Interface
  • Process Control
  • Data Acquisition
  • Battery Operated Systems

How-To

The following sample assumes that you're running the latest official Raspbian distribution, that you're logged in as root and that you haven't yet customized Raspbian to use SPI from a Python script. By default, the kernel module managing SPI communications is not loaded on Raspbian, so let's ensure that the 'spidev' device is available.

[email protected]:/# lsmod
Module                  Size  Used by  
snd_bcm2835            12808  0  
snd_pcm                74834  1 snd_bcm2835  
snd_seq                52536  0  
snd_timer              19698  2 snd_seq,snd_pcm  
snd_seq_device          6300  1 snd_seq  
snd                    52489  5 snd_seq_device,snd_timer,snd_seq,snd_pcm,snd_bcm2835  
snd_page_alloc          4951  1 snd_pcm  

If 'spidev' device is not listed, we need to remove it from the kernel module 'blacklist' so that it's automatically loaded on the next boot:

[email protected]:/# nano /etc/modprobe.d/raspi-blacklist.conf  

Put a hash character in front of the 'blacklist spi-bcm2708' statement and save the file:

#blacklist spi-bcm2708  

then, manually load the SPI device:

[email protected]:/# modprobe spidev  

The command should just complete without returning an error. Validate the list of modules:

[email protected]:/# lsmod  
Module                  Size  Used by  
spi_bcm2708             4401  0  
spidev                  5136  0  
snd_bcm2835            12808  0  
snd_pcm                74834  1 snd_bcm2835  
snd_seq                52536  0  
snd_timer              19698  2 snd_seq,snd_pcm  
snd_seq_device          6300  1 snd_seq  
snd                    52489  5 snd_seq_device,snd_timer,snd_seq,snd_pcm,snd_bcm2835  
snd_page_alloc          4951  1 snd_pcm  

The 'spidev' device should now be available.

Next, install the 'git' package. It will be needed to install other packages from Github.

apt-get install git-core  

Install the 'python-dev' package. It will be needed to compile the 'py-spidev' package.

apt-get install python-dev  

Download and compile the 'py-spidev' package.

[email protected]:/# cd /home  
[email protected]:/home# git clone git://github.com/doceme/py-spidev  
[email protected]:/home# cd py-spidev/  
[email protected]:/home# python setup.py install  

At this point, SPI is available from Python 2.7. Assuming that you have wired the MCP3008 to the Raspberry Pi's SPI bus using CE0 as the 'chip select' pin, you can read all eight analog inputs using the following Python script.

[email protected]:/home# nano adc.py  

Paste the script below in the editor and save it.

import spidev  
import time    
spi = spidev.SpiDev()  
spi.open(0,0)    

# read SPI data from MCP3008 chip, 8 possible adc's (0 thru 7)  
def readadc(adcnum):
          if ((adcnum > 7) or (adcnum < 0)):
                  return -1
          r = spi.xfer2([1,(8+adcnum)<<4,0])
          adcout = ((r[1]&3) << 8) + r[2]
          return adcout

while True:
          for adcInput in range(0,8):
                  print "ADC(", adcInput,")=", readadc(adcInput)
          time.sleep(1)  

To execute the script

[email protected]:/home# python adc.py  

Sample output using a 10K Ohm trimpot connected to the ADC's pin 3 and all other pins pulled down to ground using a 10k resistor.

ADC( 0 )= 0  
ADC( 1 )= 0  
ADC( 2 )= 0  
ADC( 3 )= 507  
ADC( 4 )= 0  
ADC( 5 )= 0  
ADC( 6 )= 0  
ADC( 7 )= 0  

Credits go to Jeremy for his work on the 'py-spidev' Python module which makes working with the MCP3008 straight forward. Alternatively, checkout wiringPi's SPI functions if you prefer using a 'C' API.

Relay for micro:bit (micro:bit Relay board)

The MonkMakes Relay for micro:bit is a solid-state (no moving parts) relay that allows an output of a micro:bit to turn things on and off.

A micro:bit can turn an LED on and off directly, but anything more powerful requires something like a relay or a transistor. Using a transistor to switch something on and off requires a shared ground connection with the micro:bit and a knowledge electronics that you or your students may not be ready for. The MonkMakes Relay for micro:bit is much easier to use, acting like a simple micro:bit controlled switch.

This relay can be used to switch low voltage devices such as light bulbs, a motor, a small heating element or even a string of 12V LED lighting. The voltage needs to be kept under 16V, but the relay will automatically protect itself against too much current.

FEATURES

  • Solid-sate relay (up to 2 Amps)
  • Active LED indicator
  • Resettable ‘polyfuse’ to protect against over-current

Getting Started

Connecting your micro:bit

The Relay requires just two connections to the micro:bit. One to GND (ground) and one to whatever pin is to be used to control the relay’s switching action.

When attaching the alligator clips to the micro:bit, make sure that the clips are perpendicular to the board so that they are not touching any of the neighbouring connectors on the micro:Bit edge connector.

Here’s an example of how you could wire up a MonkMakes Relay for micro:bit to turn an old fashioned light bulb on and off.

HEX File

The quickest way to try out your relay is to DOWNLOAD THIS HEX FILE >and then copy it onto your micro:bit. The program will turn the relay on and off once a second.

JavaScript Blocks Editor

Set the controlling pin to 1 and the relay contacts will close, set it to 0 and the contacts will open again. Its as simple as that. So, to make your relay turn on and off once a second, open the Blocks Editor, add a forever block and then the digital write blocks from the pins category and the pauses from the basic category.

MicroPython

Paste the following code into the Python window and then Download the file and copy it onto your your micro:bit.

from microbit import *

while True:
    pin0.write_digital(True)
    sleep(500)
    pin0.write_digital(False)
    sleep(500)



Analog Outputs

The latest MonkMakes Relay for micro:bit can do more than just switch things on and off. It can also be used with micro:bit analog outputs. Look closely at your Relay for micro:bit and is it has the version number v1ev (under the word ‘Board’) then it can be used with the ‘analog write’ block in the blocks editor or the ‘write_analog’ function in MicroPython. If your board has the version number v1e then it is not suitable for use with analog outputs – sorry you were unlucky to get one of the small batch of first boards to be sold.

The output of the Relay for micro:bit is not linear at low PWM and high PWM values as the following chart illustrates.

The y-axis shows the current in mA for a test load resistor supplied from a constant voltage source. The x-axis is the analog write value (0 to 1023). As you can see, there is a dead zone up to a analog output value of about 100, followed by a relatively good linear region right up to about 1000, after which the output effectively becomes ‘on’.

The tests were carried out at the default PWM frequency of 50Hz for the micro:bit. Lower frequency PWM is expected to produce more linear results.

The MonkMakes Relay for micro:bit is a solid-state (no moving parts) relay that allows an output of a micro:bit to turn things on and off.

Kitronik Motor Driver Board v2 for the micro:bit (micro:bit motor driver)

This motor driver board for the micro:bit allows two motors to be driven with forward, reverse, and stop control, and allows access to the other pins.

This board provides a simple way to add motor driving capability to a micro:bit. It allows two motors to be driven with full forward, reverse & stop control. It has terminal blocks to connect four input devices and a regulated 3V supply is fed in to the 80 way connector to power the inserted micro:bit.

In this new version, the pins from the micro:bit are now broken out to pads on the end of the motor driver board. These pads can either be soldered onto directly, or they are the correct spacing for our PCB pin headers (see image below for a close up of the new pads).

It is ideal for designs such as buggies (see below).

It includes an integrated edge connector slot for your micro:bit to easily slot into. It also features external connections to the buttons A and B inputs. This allows additional switches to be connected to the motor driver board and the state of these can then be read by the micro:bit.

Get up to speed quickly. Example Microsoft TouchDevelop code and example connections in the datasheet (below).

Servo for micro:bit (servo for micro:bit)

The MonkMakes Servo for micro:bit board provides a really easy way to attach up to three servomotors to a BBC micro:bit. The board requires a power supply or battery pack to provide 5 or 6V to the servomotors. It includes a voltage regulator that will supply 3V back to the micro:bit, so that you don’t have to power it separately.

Features

  • Header pins for three servo motors
  • Up to 2A total can be supplied to the servo motors
  • Regulated 3V output to power your micro:bit
  • Polarity protection for the servomotors
  • Electrolytic reservoir capacitor for the servomotors
  • 1kΩ series resistors to the control signals to prevent accidental sort-circuits of the micro:bit’s output pins.
  • Orange LED to indicate that the Servo for micro:bit board has power.

Connections

The picture below shows a typical setup using the Servo for micro:bit board.

The following connections have been made:

  • 3 x servomotors plugged into header pins. These need to be the right way around, with the control signal (yellow or orange wire) to the left (pins marked c).
  • Alligator clip lead from GND on the micro:bit to GND on the Servo for micro:bit board.
  • Optional alligator clip lead from 3V on the micro:bit to 3V on the Servo for micro:bit board. You only need this if you want to power the micro:bit from the same battery pack as the servomotors. If you want to power the micro:bit over USB or the JST battery connector then you do not need this connection.
  • Alligator clip leads between P0, P1, P2 on the micro:bit to the Servo for micro:bit board. These need to match up with the servomotors you are using, so if you only need the board for one servomotor, then just connect P0 on the micro:bit to P0 on the Servo for micro:bit and make sure that there is a servomotor attached to the header pins marked 0.
  • Power to the screw terminal on the Servo for micro:bit. Typically this will be a 4xAA battery pack or other power supply. Make sure that the positive lead goes to the screw terminal marked with a +

Test Software

To check that everything is working, this Blocks code project will get you started. Flash it onto your Servo for micro:bit and the servo arms should all start waggling in a random manner. You can see a video of this in action here.



The servo write pin block allows you to set the angle of the servomotor’s arm between 0 and 180 degrees. Note that servomotors, will not usually travel a full 180 degrees so you may find the actual range is more like 10 to 170 degrees.
