Widerstand ist Zwecklos: An Ohmmeter Color Code Lamp

Sebastian created Widerstand ist Zwecklos, an ohmmeter lamp that displays resistor color codes. He writes:

“Widerstand ist zwecklos” is german for “resistance is futile”, but also “resistor is useless”, which is absolutely the point in this project. i teamed up with my dear friend jan and we created a device that measures resistance and displays it as a resistor color code. an optional cheat mode also displays the resistance as a decimal number. needless to say it is shaped like a giant resistor.

  1. That is such a cool idea. I wish I had thought of that! I can see using the Arduino A/D and 9 PWM channels (might need the Mega for that) to control three tri color led’s.
    Simply Brilliant!
