BBC micro:bit V2.2 Go - Starter Pack The novelty of micro:Bit for a more lively introduction to technology for children. The micro:bit is a pocket computer that can be encoded, customized and controlled for the implementation of digital ideas and games. It measures just 4x5cm and features a fun and easy to use design, so users can create anything from games and animations to slick stories at school, at home or anywhere - all it takes is imagination and creativity. It is fully programmable. This means that each of its LEDs can be individually programmed as can its buttons, inputs and outputs, accelerometer, magnetometer, Bluetooth 5.0 technology, microphone and speaker. It contains a quick start guide in the same package. Code B0125 Available Regular price €23.95 -€0.96 Price €22.99

MAX9812L Amplified Microphone for Measuring Sound The MAX9812 is a sound amplifier specially designed to treat the signal coming from microphones.We can use it together with Arduino to measure sound from a processor like Arduino.When we saw the modules with microphone we commented that, in general, the signal generated is too low to be registered correctly.If we want to be able to measure sounds, we will have to amplify the signal. The MAX9812L has single / dual inputs, fixed gain of 20dB, bandwidth of 400 kHz, low noise and low signal distortion 0.015% THD.There are two models, its supply voltage is 2.7V to 3.6V.We can use the sensors with MAX9812 for applications that require measuring the intensity or frequency of the sound.
