It depends on how short the pulse is. It may pulse the LED too quickly for you to see.
A 510 ohm resistor should work for 12V and a typical LED. Be sure to connect it the right way.
Try it. It's not difficult to do.
Yep, and 20 days for the OP should be enough to do it and reply here...
Hey, im a bit late and im probably too late for helping the thread owner, but maybe it will help somebody else landing here. IĀ“ve been struggeling around with a kind of this coin acceptor for days. My Problem: for two out of five coin types there was no pulse output.
I finally found out if you define the number of pulses in "P", you have to choose the number without dot. I accidentially chose a number with dot. If youĀ“re coming in negative number range by clicking the minus button, you will get numbers with dot and no pulse is given
Wrong setting for me:
correct setting for me:
THIS!!! I tried everything. Le dot. My coin acceptor "beeps" on pulses, and i thought it was broken. It beeped randomly but detectected the coins, and said the values. Minus values. Goddamnit!
