That resulting signal is a square wave, which is an easy target for the Arduino to measure. That timing measured from the square wave can then be used to calculate the inductor’s value.

RT & Arduino experiment was successfully conducted at my own lab using the ALPS-EC11E RT and Arduino UNO-R3, ported with a sketch borrowed from the web. You may ask why I did not prepare my own sketch ...

Sometimes you don't need a large microcontroller to get your work done. In this installment, TK teaches us how to use the ATtiny combined with Arduino to use the PWM function found on this chip.

Using motion detectors and an Ardunio you can add a little extra wow to your Halloween displays this year. This article covers the circuits and the code to make that happen.
