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...

Octopus TMP36 Temperature Sensor Brick for Arduino and micro:bit is a temperature sensor with low voltage and accurate celsius read. It can provide voltage output,which forms a linear relationship with celsius temperature. TMP36 do not need any external...

OCTOPUS Potentiometer is a simple linear sliding potentiometer electronic building block module which can be used as a resistor divider output, HID control panel, or in the electronic building block kit. News: All of the Octopus bricks support Scratch...

Octopus Electronic Bricks, you can use them to build electronics projects just as easily as piling bricks. By using Octopus electronic bricks, you can connect Arduino/Freaduino compatible boards easily with various digital, analog and I2C/Uart...

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...

A transistor that will allow other items to be switched where the micro:bit would not be able to. Items such as motors, larger speakers, relays and so forth, up to 1A total load. A current limiting resistor is in the circuit to protect the micro:bit...

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...

A small microphone with amplifier & threshold setting. It can detect when sound reaches a certain level. It can not detect a particular frequency and there is no support in the micro:bit programming environment at present for it to analyse...

A small motor that moves it's output arm to a position depending on the signal sent to it with a reasonable degree of accuracy & repeatability. The brown lead with the black croc clip goes on to GND, the yellow lead goes on to the Pin 0, 1 or 2 that...

A 3V Light Emitting Diode as an additional LED. It uses a high brightness low current LED and includes a current limiting resistor to protect the micro:bit’s output. The black lead goes on to GND and the green lead goes on to whichever Pin 0, 1...

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...

Provides a variable voltage to an analog input via a twist knob – a volume control if you will. Can be used for any application where a user input across an analog range is required – for instance changing the frequency of the music output or...

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...

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...

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...

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 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.

Compatible with micro:bit V1 only!   Caution! The BBC micro:bit, and MI:power board are NOT included. This is the ORANGE version of this case. This case has been designed to protect a BBC micro:bit with...
