Guys my fren need a timer to control a RC car.
It supposed to work like this,we set the time for the car to operate.
For example we set 5 min on the timer,so the car will only move for 5 min n then stop.
He need 3 timing,5 min,10 min and 30 min.
So the timer must be an adjustable one with a switch.
After the time finish,the car will stop,then we need a reset button to set the time again.This timer will be connected to a relay which connected to the motor of the car.
I think this can be achieved with 555.But i dono much abt 555.
Hope u guys can help me.

I think first circuit here should be more reliable and easirer to adjust than the 555 one: http://www.zen22142.zen.co.uk/Circuits/Timing/24hour.htm
