Let me clarify a bit, the leds are to represent the number of times a number was guessed incorrectly for a game I am making. Each time a choice was guessed incorrectly I wanted another led to light up to signal that the guess was wrong. the leds would keep lighting up every time someone guessed...
I am working on a circuit that requires 3 leds to light up. I want to have it so each time a high (or low it doesn't matter either way) signal is received another light comes on until all three are lit up and then the setup can be reset to do it again.
yes that is the website I am using for wiring the bcd, my problem is not which imputs to attach to, but how to randomly make those inputs go from high to low or from low to high.
I am currently just trying to have it randomize once, not repeatedly. The four inputs are actually the inputs on a bcd to decimal decoder. The research I have done is next to none, because every time I look up my issue I get results for mine craft.
I am building a circuit that requires 4 inputs to be randomly set either high or low. I do not know how to make these inputs set low or high randomly and I don't want to use a microprocessor. Any help would be much appreciated
