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

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.

PiStep2 Quad Stepper Motor Control Board for Raspberry Pi (PiStep2 stepper hat)
Description:

This neat little board plugs directly into the Raspberry Pi GPIO header and provides 2 or 4 connectors for small stepper motors

  • Fully Assembled - No Soldering Required
  • Raspberry Pi Zero Form Factor - works with all versions of Raspberry Pi with 40pin GPIO connector
  • Stepper motors and Raspberry Pi not included

Various Power Options:

  1. Powered from the Raspberry Pi 5V
  2. From the 2-pin Terminal (whatever voltage is required for the motors)
  3. Micro-USB - 5V only

Pinout is simple:

  • Physical pins 11, 12, 13, 15 for Motor A (GPIO 17, 18, 27, 22)
  • Physical pins 16, 18, 22, 7 for Motor B (GPIO 23, 24, 25, 04)
  • Physical pins 33, 32, 31, 29 for Motor C (GPIO 13,12,6,5)
  • Physical Pins 38, 37, 36, 35 for Motor D (GPIO 20,26,16,19)

Each pin has an associated white LED so you can see the stepper signals going through

Power Supply Alternatives

  • Jumper VCC-VSTP (default). Power from the motors is taken from the Raspberry Pi 5V line
    • Micro-USB into Raspberry Pi. 5V for the Pi and the stepper motors goes through a poly-fuse which can trip if 2 motors are used simultaneously
    • Micro-USB into the PiStep board. 5V for both the Pi and the stepper motors is provided directly from the 5V USB input so no problems with 2 motors at once
  • Jumper VSTP-VIN. Power for the motors is provided from the 2-pin screw terminal, so can be any voltage that the steppers can handle. Ensure you use the correct polarity! We recommend to keep it below 12V. You will find that the stepper motors can go up to 9V and will be able to step faster, the higher the voltage that is applied, but there will be some deterioration of the life of the stepper motor at a higher voltage.

Python Programming

Please see the excellent example here for some pointers. You will need to change the pin numbers as above and also change the speed so it steps at a visible rate. You may also want to remove the print statements to speed it up. The lines in Red below are changed from the original to operate Motor A.

# Use BCM GPIO references
# instead of physical pin numbers
GPIO.setmode(GPIO.BCM)

# Define GPIO signals to use
# Pins 18,22,24,26
# GPIO24,GPIO25,GPIO8,GPIO7
StepPins = [17,18,27,22]

# Set all pins as output
for pin in StepPins:
  print "Setup pins"
  GPIO.setup(pin,GPIO.OUT)
  GPIO.output(pin, False)

# Define some settings
StepCounter = 0
WaitTime = 0.01

ScratchGPIO Programming

These pins are identical to those required by ScratchGPIO and therefore can easily be driven using simple Scratch commands:

Set motor type for Scratch to be Stepper motor

Set the position of the stepper motor A

Set the speed of the stepper motor A

SONOFF 4CH PRO R3 AC100-240V 50/60Hz 10A 2200W 4 Gang WiFi DIY Smart Switch APP Remote Control Works with Alexa and Google Home (sonoff 4ch pro R3)
Overview:

SONOFF 4CH R3 & 4CH PRO R3 are both 4-gang DIY Wi-Fi Smart Switches designed to give you the ability to integrate smart control into your existing home to enable a smart home. Each smart switch has 4 gangs that can be used to control lights and other home appliances at the same time in four areas of your home. There is a major difference between 4CH R3 and 4CH PRO R3, which is 4CH PRO R3 is designed with an additional function for RF control. The function is purposely adopted to make you turn on/off the device connected with 4CH PRO R3 via the RM433 remote controller.
Actually, SONOFF has ever released two types of 4-gang smart switch (4CH R2 and 4CH PRO R2.) which comes with almost same functions with 4CH R3 and 4CH PRO R3. But all the above units are still different in 3 working modes including self-locking, interlock and inching mode. The new improvement on 4CH R3 and 4CH PRO R3 compared with 4CH R2 and 4CH PRO R2 is for users to set these 3 working modes on eWeLink APP instead of the hardware itself, easier to operate. So you can enable self-locking mode to turn on/off 4 connected devices separately, interlock mode to turn on 1 connected device every time and turn off the rest of devices simultaneously and inching mode to turn on 1 connected device and then make it turn off automatically after a given time (0.5 - 3600s). For the device away from the switch, you can create a moveable space in virtue of a DIN rail to make them be connected. Simply activate devices through your voice when the switch works with Alexa and Google Home smart assistant.

Features:

- Remotely control connected lights or devices via APP
- 3 working modes with self-locking, interlock and inching mode for even remote control garage door and roller blinds
- Support scheduling a timer to make devices automatically start and stop to work
- Customize smart scenes to make the device connected with the switch to trigger other devices
- Share the control permission of devices to other accounts to control together
