Ok heres the deal. I have a permanent 5V feed going into the postive side of the PicAxe, and a switch on the negative (im using NPN transistors to power LED's). However I also have a switch for input to pin 3 which is also a negative feed. When I flick this switch to pin 3 the Picaxe turns on...

Hi there, Attached is my current circuitry for an LED strobe light I am creating. I am having problems wiring in a transistor. My circuit consists off 27 LED's wired in series to the Pin 1 output with 220R resistors. I have tried wiring in NPN and PNP transistors (due to lack of current from...

Hi There, Just programmed my first chip. It is a simple 3 LED chaser. However when it is hooked up to a 5V supply, the two LED's appear on and very dim on pins Out 1 and Out 2 while the other flashes. The flashing one is on Output 0. Also I don't have any resistance on the LED which must mean...

Hi Guys, I am currently building an LED Chaser which I wish to run off a 14.5V Supply of the Car Battery. I have the code typed up, the LED's ready (with 620ohm resistors), just need to buy a 08M Chip and solder that into the circuit. I have had a small hunt around but am wondering what...
