I am working with Arduino uno Mega. I have no too many informations about circuts, leds and buttons.
I have to finish a project with 14 Buttons and too many Leds. I want to decrease number of led. I need your help.
I want to ask if it is possible to control one led with a few different buttons. For a project I need it. For example I have 9 leds and 9 Buttons. When I push to first button I want to let 1., 3. and 5. Leds turning on. When I push the 2. Button, I want to let 1.2. and 3. Leds turning on. I have tried to add 3 Signal cable to positive end of a Led. When 2 Signals connected to one led, led stops turning on.
If I could achieve this, instead of 98 Leds, I will work with just 38 Leds.
Is it possible what I want.?
