by Raymond Genovese @ www.allaboutcircuits.com: The idea of a single chip radio is intriguing. The prospect is especially interesting to me because, frankly, I envy the analog skills I associate with building a radio receiver. When I browsed the circuit literature in the area, I came...

"webgeeks" show us how to setup an Arduino UNO on a breadboard - aka bare minimum arduino: If you are like and me and enjoy building electronic projects then you might have worked with the Arduino Uno. The Arduino uno is the most popular micro controller of the series and has a large...

Bluetooth is typically a low power, medium range device, in fact it can reach up to 10 meters. Bluetooth operates on the same frequencies as WiFi, 2.4Ghz.Connections are normally one to one meaning no group communication is allowed by the protocol. The connection is established by a...

One of our visitors tipped us with his latest project, an Arduino RGB LED controller using low Rds-on MOSFETS, designed in Solo-PCB. This Arduino shield is designed to drive RGB (Red Green Blue) LED strips by using PWM (Pulse Width Modulation) method. It can brighten up and down each...

In this video we are going to learn how to build our own voltmeter using a very inexpensive sensor. The voltage we measure is then displayed in a Nokia 5110 LCD display. This project is very easy to build and great learning experience. With this project we can measure the voltage of...

educ8s.tv has a new video on how to use a fingertip sensor with Arduino. If you want to add biometric security features to your Arduino projects, an easy way to do so, is to add a fingerprint sensor module to it. In this video we demonstrate how easy to use a fingerprint sensor with...

This is an Arduino tutorial on how to detect lightning from far away. In this tutorial, we will build a lightning detector using an Arduino Uno, a few resistors and some jumper wires. Most lightning detectors often cost too much for the normal hobbyist, however this does not mean one...

In this video educ8s.tv is  going to show us how to use the SD card slot of the popular 1.8" Color TFT display which uses the ST7735 driver. Then we will save some bitmap images in the SD card and we will display them on the display. In other words, we will build a simple Photo Frame...
