Hello,
I am building a model for a product design class and I would like there to be a functional LED on it, controlled by a tact switch. There is not enough room for a toggle, so a latch will be necessary.
I purchased a flip-flop latch switch on ebay because I do not have enough experience with circuits to build one myself. I wasn't able to understand all the debouncing and other logic required.
Here are the schematics that were provided with the circuit:
What I did: Positive end of 3V button cell was wired to tact switch, VCC, and positive leg of LED. negative leg of LED was wired to Vo. Other end of tact switch was wired to Vi. Negative side of button cell was grounded. I did not use a resistor after the LED as the input voltage was already correct for the LED.
With this setup I was unable to get it to work. All help getting this working would be appreciated!
