The MonkMakes Speaker for micro:bit is a neat little amplified speaker that connects to the micro:bit using alligator clips. Despite its small size, the speaker is pretty loud. Please note that the individual boards are packed in antistatic bubblewrap...

A capacitive moisture meter with temperature and relative humidity measurement. Compatible with micro:bit, Raspberry Pi, Arduino, Pico and most microcontroller boards. Monitor soil moisture, temperature and relative humidity measurement with the Plant...

The MonkMakes Servo for micro:bit 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...

A pushbutton on a lead for when you need another pushbutton or you want it away from your micro:bit One lead goes on 3v or GND and the other lead goes on 0, 1, or 2. For advanced applications it is feasible to connect two pins with the pushbutton. It...

We got fed up with low quality, overly-long alligator clip leads, so we got some made to our specification. Our leads are supplied in a bundle of 10 leads. Two each of black, red, white, green and yellow. Each lead is 185mm (7.5 inches) long from tip to...

A rechargeable battery and acrylic case kit for your micro:bit. The Charger for micro:bit automatically charges while you are connected to USB. Make your micro:bits mobile without having to continually hunt for AAA batteries. Resources Datasheet...

The Water Sensor Provides a variable analog reading depending on how wet/damp the sensor is. Good for plants or fingers. The black lead goes on GND, the red lead goes on 3v and the blue lead goes on whichever pin is being used in the program. This...

Click Me to Download the Instructions for this kit. The Servo Kit for micro:bit makes it easy to connect up three servomotors from your micro:bit. Not only that, but the kit also comes with three servomotors and a battery box. Just add a micro:bit and...

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. This relay can be used to switch low voltage devices such as light bulbs, a motor, a small heating element or even...

The MonkMakes Power for micro:bit opens up lots of ways of powering your micro:bit. This tiny board has a standard DC barrel jack socket at one end and provides a regulated 3.3V output that you can use to power your micro:bit using the JST battery...

A very accurate temperature sensor using a calibrated chip called a TMP36GZ. It is accurate to ±1°C at +25°C. At this temperature it outputs 750mV. It changes by 10mV per °C. The black lead goes on GND, the red lead...

Plug a servo meter with 5.4mm (0.1 inch) header socket in, and connect croc/alligator clips to the rings, so that you can easily connect a servomotor to a ring-based microcontroller, such as the BBC micro:bit, Adafruit Circuit Playground Express or...

A standard 3.5mm stereo headphone adapter to two crocodile clips for Micro:bit This won’t give you stereo, but it does play in both ears! The black lead goes on GND, the green lead goes on 0. It doesn’t matter if they are put on the other...

A type of buzzer – it has to be driven by a pulsed output. It’s tuned for around 2kHz when it will be at its loudest but will produce a tone across a wide range of frequencies. In the Block Editor, the black lead goes on to GND and the blue...

The MonkMakes RGB LED for micro:bit can be used to make any colour by controlling the red green and blue levels. Handily mounted on a PCB it connects to the micro:bit using alligator clips. Resources Datasheet (PDF) Instructions (PDF) Hi Res Images...

A simple buzzer with transistor that can be powered by the micro:bit. Costs more than a headphone adapter but far less than the mini-speaker – its best use is to act as a sounder for an alarm or similar.

Description A small version of the PIR that is used in a typical burglar alarm. It triggers when a warm body passes in front of the detector. It has some range / sensitivity setting capability and the duration of the output can be set. The black lead...

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...

Good for detecting boxes, drawers or doors being opened and much more. The black lead goes on GND, the red lead goes on 3v and the other lead goes on 0, 1, or 2. This item is somewhat polarity sensitive, the red & black leads need...

An external light sensor for all your light sensing needs. The black lead goes on GND, the red lead goes on 3v and the other lead goes on 0, 1, or 2. This item is polarity sensitive, the red & black leads need to be on the correct...
