In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. Every step will have the code, the schematic, photos of the project ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

This DIY gas leakage detector is designed for educational and basic monitoring purposes. For critical safety applications, ...

On the hardware side, we really can’t overstate how simple this project is. A common four-digit LED display is connected up to an Arduino Nano, which is then plugged into the computer for power.

So, for a quick way to see how much juice your AAA, AA, C, or D batteries have left, build this Arduino-based battery tester, which can display battery life via a string of LEDs. The next time you ...

[Alex] needed a project for his microcomputer circuits class ... it looks like multiple LED’s are lit up simultaneously. [Alex] planned to use an Arduino to control this display, but it ...

In our lab led by Dr. Kambiz Pourrezaei, the subject's reaction to pain and the function of the body in response to pain is studied. The technology to create an NIRS system involves the integration of ...
