Can someone help me with common cathode leds and push buttons? Answered
Im planning on doing a thingy like this for my son, can it work?
Im going to use a 3V 1A power source to connect 3 push buttons to a common cathode led, like on the image included.
I was planning to use this led:
and switches like this:
is says: Light Voltage DC 3V
In my mind it looks like this: if u push the red, the led will turn red, and u can add additional colors to it with the other 2 buttons.
Could this work?
If I figured it out good, I wont need a resistor for the blue and green, but I will need one for the red. How big it should be?
Is it a good setup that I solder the positive to the switches and the black/negative to the one led?
Can I add an another lead from the power supply to an another independent switch and single color led?
