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.

Speaker for micro:bit (micro:bit speaker)

The MonkMakes Speaker for micro:bit is a neat little amplified speaker that connects to your micro:bit using alligator clips.

Features

  • Amplified output
  • LED ‘power on’ indicator
  • Reverse polarity protection

Getting Started

Connecting to your micro:bit

Connect the Speaker to the micro:bit as shown below. 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.

HEX File

The quickest way to try out your speaker is to DOWNLOAD THIS HEX FILE and then copy it onto your micro:bit. Press Button A to hear a tune being played.

JavaScript Blocks Editor

Visit the Blocks Editor in your browser and then from the input section add an on button A pressed block then from the music section add a start melody block and select the tune you want to play (in this case, entertainer).

Click Download and then copy the file onto your micro:bit.

You can also make a simple musical instrument, using this tutorial: https://makecode.microbit.org/projects/hack-your-headphones/code

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 *
import music

while True:
    if button_a.was_pressed():
        music.play(music.ENTERTAINER)

When you press button A you will hear the tune “The Entertainer” play through the speaker.

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.
