Hi all, I photograph wildlife at night using camera traps. I'd like to try some shots where I adjust the aperture and focus during a long exposure (e.g., 30s). Ideally, at a defined point in the exposure, a microcontroller would rotate both the focus and aperture gears (over a period of < 1s...

I have a really basic question, but my googling isn't providing a clear answer (I'm not good with circuit diagrams and electronics jargon) so hoping someone can chime in. I've only used my picaxe chips with digital high/low inputs, like a PIR sensor. I'm wondering how to use a switch as an...

Hey all, I've been frustrated by false triggers on my PIR triggered camera traps. I want to switch to an ultrasonic rangefinder as the sensor; setting a range of distances that trigger the camera to take a picture. For example, aim the sensor at a tree 3m away, then if something is measured...

Thanks a bunch for the info and code. the micro/milli issue would have had me scratching my head for a while had you not pointed it out. The polling loop looks like just the trick. Hopefully I can get this false trigger thing under control quickly and get this camera back out. I'm due for...

Hi all, I use Picaxe 08M2 chips in motion sensing camera traps. My current setup is really simple: I run a PIR sensor to my input pin, and my output pins go to optocouplers that control the camera shutter and focus via a wired remote. I've been having trouble with false triggers. My...

I'm using an 08M2 chip in a motion-activated wildlife camera. It works great, but I wanted to add a way to adjust the delay time between motion sensing and pictures, without having to reprogram the board or solder something to it. I am using the AXE021 Picaxe 08 proto board, which has a jumper...

Hi all, I was hoping to control a Mdfly mp3 player AU5121 (Tenda TBD380) with a Picaxe 08M2 chip. I ordered 2 units and they both arrived in parallel mode. I've tried to read up on how to use this device with a Picaxe and it seems everyone is using it in Serial mode. Has anyone had luck using...

Hello, I have rather simple project where I am using a picaxe chip to operate a motion activated camera. The input is a parallax PIR motion sensor, and the outputs are optocouplers which close circuits on my camera's remote to make it focus and/or take a picture. I got the project up and...
