Hi.
Based on this .. Arduino Reaction Timer with LCD Display | derekmolloy.ie
I'm trying to count two different times based on two capacitive sensors.
As you can see in my test code
- When StartSwitch pressed and BaseSensor is 1 the code waiting for a random amount of time and then RedLight goes ON
- Then i'm counting the time in millis between LED ON and Release BaseState and later displaying it in my LCD.
What i also want to count ...unsuccesfully so far .. is the time between the BaseState released and the EndState=1 and then display it to my LCD.
Can please someone help me ?
Thank you in advance
