The MonkMakes Switch for micro:bit is a solid-state (no moving parts) switch that allows an output of a micro:bit to turn things on and off.
This board 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 switch will automatically protect itself against too much current.

The MonkMakes Amplified Speaker 2 is an easy to use amplified speaker on a circuit board.
The board needs a 3.3 to 6V power supply that can be provided by a Raspberry Pi or Arduino. Audio input will normally be to the 3.5mm stereo audio jack socket, which is mixed to a mono signal.
The product includes a separate input with low-pass filter for use with PWM/PCM audio.

Now updated with a new chapter on the Raspberry Pico W, this book will teach you Python programming and some basic electronics without assuming any prior knowledge of either subject.
The book initially focusses on Python programming, building up a Morse Code example using the Raspberry Pi Pico’s built-in LED. Once you have mastered the basics of coding the Pico, the book will introduce electronics, showing you how to use sensors, switches, LEDs, servomotors and displays attached to your Pico or Pico W.
All the parts used in the book are available in the companion kit, Electronics Kit 1 for Pico (SKU00088)

This board is designed to dock with a BBC micro:bit using the micro:bit's edge connector. The board is a true CO2 sensor that also measures temperature and relative humidity.
Features
- Low power -- power directly from your micro:bit
- CO2 0-5000ppm, temperature and relative humidity measurement
- Has a makecode library to simplify programming
Please note that this product, while it has many of the same features as the MonkMakes CO2 for micro:bit is based on a completely different sensor and is not a direct replacement for use in the Living Space project (amendments will need to be made to the teacher's notes).

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.
