I have run into an issue where I do not know how to implement a timer into the given circuit, I was seeking advice to see if I could do this through code or by implementing a component into this circuit to do so.
I have plans to replicate this circuit a number of times. Each one will act independently, activating the next one through the influx of light near its Photoresistor (LDR). This will hopefully create a continuous wave of light. As this will be used in a dark room I do not want the lights from the next one to light up and cause the one before it to light up, This is where I need the timer to come in. Once the Photoresister allows the power to travel onto the LED I need the LED to shut off after a second and stay off for a minimum of 5 seconds. This should give the wave of light enough time to get out of the reach of the first circuit, so on, so on.
I will be using my Arduino Mega 2560 to program each of the ATtiny85-PU20's if this helps.
Any assistance with this would be greatly appreciated.
