I've wired up a bunch of admin buttons in my cab, along with LED lights that show which ones are active. The idea being I can disable selected admin buttons via internal switches for use at parties, etc.
There are 12 LEDs wired in parallel, each with their own resistor.
I'm pretty sure it's all wired right, but the LED lights don't come on. After a few seconds, the positive wire coming off the 5V line at the PSU gets really hot.
What might I have done wrong?
I'm thinking I might have used wires the wrong thickness or length, but I'm no expert on electronics.
