In addition, customizable illumination in public and private spaces is required to increase sales of light emitting diode circuits. However, chip on board light emitting diodes sales may be ...

The microcontroller running the code is an ATtiny13 on a Sparrow board. He’s using an everyday LED as a detector diode and an internal pull-up resistor in the ATtiny13 for the bias voltage.

The volume control puts an AC load on the detector causing distortion in the audio. The diode used has to be a germanium type or a hot carrier diode that has a low forward conduction voltage. The ...

By using a few simple components, it's possible to build a low-cost Geiger detector ... current is rectified by diode D1. A simple Zener-diode stabilization network circuit using D2 supplies ...
