I used the same circuit arrangement as in the last video but with the addition of a piezo speaker element. A negative-coefficient thermistor is used along with a 1K resistor as the “potentiometer” sensor…
I’m starting to develop a generalized driver for Pulse Motors using the Arduino OSEPP Uno clone. Here I’ve gotten the sensor input system programmed into the unit, and I show its function and serial…
Color Organ featuring Software Fast Fourier Transform in real time. Please see the earlier Color Organ videos for the program sketch download location and the full credits to the folks who wrote the original…
Note: improved and commented program sketch for the system, curing some of the problems, can be downloaded at: (new file, minor bug fix) www.mediafire.com Here’s the system taking shape. I am to the stage…
Here’s a small and easy inductance meter made from the Arduino and some other parts. Old TVs are a great source for capacitors, diodes, and even some chips: I found this handy dual lowvoltage…
Using PulseFire As a Arduino Controlled Voltage Data Logger (Demo) first of all, i want to than welliam for his hard work!!! == PulseFire == http://open-source-energy.org/forum/showthread.php?tid=440 www.rwgresearch.com RWGresearch
I changed the code a little bit to show the resolution of the ultrasonic ranging method used by the Arduino/Ping combination. I think that the resolution is about 1-2 mm at the distance I…
here is The genset testing thread: http://open-source-energy.org/forum/showthread.php?tid=383 the Arduino code is also there. tinman’s video:
Test de sortie PWN sur Arduino UNO et un potentiomètre Tinkerkit sur oscilloscope
This little gadget is primarily for Joule Thief research, where the relative brightness of an LED must be compared or monitored as conditions change. The TSL235A is a small sensor that converts light intensity…
