In this video I'll be showing you how you can control the contrast and the back light brightness of a 1602 LCD display with just the Arduino. The contrast is typically adjusted with a variable ...

Testing for failure with a multimeter is only partially effective, whereas a dedicated optocoupler testing circuit provides ...

In this video I've created a device that can notify in real time about events that happen on a website. The project uses NodeMCU board and a buzzer to produce sound as alert. The board is programmed ...

In the maker world, it’s the Arduino and ESP32 lines that get the lion’s share of attention. However, you can do fantastic ...

Abstract: This work proposes a novel resistor-floating-resistor-string digital-to-analog converter (RFR-DAC) architecture with a 10-bit resolution for liquid crystal display (LCD) driver applications.

High quality bug reports and feature requests are valuable contributions to the project. Before reporting an issue search existing pull requests and issues to see if it was already reported. If you ...

/ examples - Example sketches for the library (.ino). Run these from the Arduino IDE. /src - Source files for the library (.cpp, .h). Please review the LICENSE.md file for license information. Please ...

Abstract: TAN resistors are commonly used in RFIC applications and are gaining acceptance in traditional CMOS designs. TAN materials, frequently used in fabrication of Cu interconnects can easily be ...

The Joule Thief Circuit is a simple and clever electronic design that can power an LED using a nearly dead battery.
