Hi guys ,
My project requires me to create a sound detector where when the micro-phone picks up noise of a certain threshold , it will light up an LED light bulb.However , currently i am facing some difficulties in lighting up the LED lights when i connect 5 microphone to the arduino uno . For example , Micro- phone A is connected to BLUE LED , Micro - phone B is connected to Green LED and Micro-Phone C is connected to RED LED. So , my task is when i speak to micro phone A , ONLY BLUE LED will light up and the rest of the LED remain off. Same goes to Micro- phone B and C. The LED lights will only light up when the micro-phone the LED light is assigned to , detects a voice or a sound. \
Below is my code, PLS PLS HELP ME!!!
