MICRO:BIT & ACCESSORIES

ELECFREAKS' micro:bit case is made of 1mm thin and light material, has a silky smooth feel, is waterproof and impact resistant, and does not interfere with expansion.

A microbit V2 is a small, pocket-sized computer that allows you to program and create interactive projects. It is an excellent tool for students, educators, and hobbyists who want to learn more about coding and electronics. However, a microbit V2 is also vulnerable to damages and scratches, which can affect its performance and longevity. To prevent this, a micro:bit case is a practical solution that protects your microcontroller while keeping it accessible for your projects.

A board for prototyping circuits. Components and wires can be placed into the board and the circuit built and tested without soldering.

Multiple boards can be interconnected.

This board has 400 tie points.

Size: 82mm x 54mm

Did you know the name bread board comes from early days of prototyping when nails would be hammered in to a breadboard and components and wires wrapped around them.

Add obstacle detection to your robotics, electronics, or Arduino project. This module has been specially selected to work on the voltage range typically found with the Arduino range of products. This economical sensor provides 2cm to 400cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3mm. Each HC-SR04 module includes an ultrasonic transmitter, a receiver and a control circuit.

There are only four pins that you need to worry about on the HC-SR04: VCC, Trig, Echo and GND. VCC and GND are for power and Trig, Echo and GND are for your signal. GND is in with the signal set since it's needed for a baseline. You can easily add this to your project and even use with the microbit if you use a separate 5V power supply.

The MonkMakes Sensor Board allows you to detect sound levels, temperature and light levels. It features ring pad connectors for use with crocodile clips make it easy to connect to the board to a microbit.

Sound Level: It senses sound level with a MEMs, which is a microphone on a chip that also features a pre-amplifier circuit. You can then use the plot bar graph block in the Microsoft MakeCode editor to display the result on the microbits LED matrix.

Temperature Level: The temperature output from the board is a voltage that indicates the temperature. This is then measured using an analog input on the micro:bit. If you want your temperatures in Fahrenheit, then multiply the temperature in degrees C by 9, divide the result by 5 and then add 32.

Light Level: The light sensor uses a photo-transistor to measure the light level and produces an output voltage that increases as the light level increases.

Features:

3V and GND connections can be made from either side and allow you to power a second board such as the MonkMakes Relay Board or MonkMakes Speaker.
