I searched the forum to get an idea of the various RF modules out there, but there are so many, I don't know which to get. So my question is, what modules have worked for you guys? Please bear in mind that I've never used radio, and am a beginner in electronics, so the simpler the better! ;)...

Ok, earlier, when I said it sorted itself out, I reset the circuit and tried again. It didn't work. So I tried decoupling caps, covering the ldr..etc, but nothing worked. I then remembered that I had connected the LDR to the same power supply as the picaxe earlier, to save time. This worked! So...

Hi, I made a 'laser tripwire' circuit using an LDR, a laser diode and the readadc function which operates a servo when the beam is broken. On the breadboard, the circuit was fine. I then soldered the LDR pot divider and laser to a separate pcb and connected this to the input pin of the PICAXE...

Hello, I started out with a PICAXE last year and have been watching the forums for some time also, but this problem really got me frustrated since the start. I can never seem to get my infra-red receiver to work. I have checked that the IR LED works using a digital camera. When I connect the...
