I needed to record some time-temperature-power data over a long period of time. So I made this Arduino simple intervalometer to control the Canon camera through its external shutter release cable jack. The system…
Here I continue to demonstrate the versatility of the simple Arduino pot-voltmeter system. NOTE: I get scrambled when I describe the mosfet pin hookup. The Load has no connection to the mosfet gate, it…
A single RC servo and a couple of cheap CdS photoresistors make the Arduino “look alive” by making a simple light tracker. With just a few lines of code you can make the arduino…
The APMC (Arduino Pulsed Motor Controller) v1.0 is a very useful tool designed for helping the experimenter who want to explore the Delayed Lenz Effect or the Magnetic Lag Effect and want to test…
Here’s a little Ultrasonic Ranger using the Parallax brand Ping ultrasonic transducer pair and the Parallax LCD display. Both are easy to use with the Arduino system. Just don’t try to supply more than…
CAUTION: Flickering lights: if you are prone to seizures or are affected adversely by strobes or flicker please don’t watch this video or build this project. I can’t be responsible for any adverse… or…
6 Output Arduino Pulsar Programmable Test Box! Open source RWGresearch.com Come to the forms for the code and schematics. open-source-energy.org You can donate to the research @ WWW.RWGresearch.com Thank you everyone! I could not…
A big thanks to all who has helped in any way! www.RWGresearch.com ! spreed the word! good things are about to happen! keep watching! The Arduino code can be found here: open-source-energy.org please make…
NOTE: Software revision available: see below I found an old sack of bulk LEDs that I’ve had for ages, and there were just enough many to make a 64-LED cube with a few spares….
By suggestion, I hooked a simple PV cell to the potpin sensor input, and recalibrated the sensor range using values read off of the Serial Monitor tool in the Arduino IDE. I show how…
