€30-250 EUR

Paid on delivery
The aim of the project is to write a code c++ based, that allows my Arduino 1 to works like a Sound Level Meter. My hardware consists into an Arduino 1 card and an analogic microphone. The code should be start to measure the voltage from the microphone, calculate the average of a reading period (eg. 2seconds) and then translate that value into a logarithmic scale (dB), according to the Leq pressure theory. Obviously the system should be calibrated, I can do it then when all will work finely.
