My 10 yo daughter has decided for her science project she wants to do an experiment seeing how much adding cars to a train slows it down. Very cool.
I already got a go ahead to buy a 2nd 153IR to set up the timer.
So is there a timer that hobbyists use to measure elapsed time on a loop or straightaway. I thought one 153IR could be used to turn on the timer and one to turn it off. (More fun than a dopey stopwatch!)
I can weight up my passenger cars and add them one at a time and make like 5 test runs each. Got a voltmeter so we can have constant and comparable voltage.
I love my daughter! This is my idea of schoolwork!
