I'd like to create a circuit with 9 LEDs and light up just one of them.
Then, after pulsing a switch, having it light one additional LED so that now two are lit. And then after pulsing the switch again, having it light up one additional so that three are lit. And so on until all 9 are lit.
I'm new to electronics so I'm not sure how to do this and am looking for some advice. I'd like it to be as simple a circuit as possible ideally because that will simplify the actual construction of it down the line.
At first I thought i needed something like an adafruit trinket and a custom-programmed microcontroller but I've been reading about the 4017 decade counter and was thinking that that might be what I need ( ? )
But with the counter, I suppose I can envisage different lights lighting up each time, but can't imagine yet how to get an increasing number of lights lit this way.
Could I ask for your advice please?
And also.. regarding sending pulses to a counter, do I need a special type of switch for that? If so, is there a name for that type of pulsing switch?
Thanks
