Discover how you can build a professional digital multimeter using Arduino that measures up to 24V DC voltage, checks resistance, conducts diode testing, and performs continuity tests. This ...

In this experiment we are going to use a element called photoresistor. This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light ...

The presented solution for measuring voltage of Zener diodes using Arduino is completely new and original. The circuit uses LM317 as a constant current source and the whole measurement process is ...

The movie Iron-Man came out in 2008. In 2010 after the sequel was released, I wanted to create an arc reactor prop to use in Halloween costumes. I documented my build on Instructables here: Build an ...

Abstract: This paper adopts Arduino DUE and Raspberry Pi for organic light emitting diode (OLED) lifetime measurement. Using digital-analog converter (DAC) port of Arduino DUE output voltage to ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

Multiplexing is a very old technology in which control signals are intermixed for the sake of being able to control more devices than there are control signals. For [mihai.cuciuc], the problems ...
