I have written and tested this code. int speaker = 2; int led[] = { 9, 10, 11}; int pressure = A1; const boolean ON = LOW; const boolean OFF = HIGH; const boolean RED[] = { ON, OFF, OFF}; const boolean GREEN[] = { OFF, ON, OFF}; const boolean BLUE[] = { OFF, OFF, ON}; void setup() …

Could use some coding help.

you should go for a pure electronic system where the sensor power the led then
