Arduino Bluetooth Tutorial HC-05
https://www.electronics-lab.com/arduino-bluetooth-tutorial-hc-05/
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 master device, which connects to a slave device. […]
DIY Arduino RGB LED Controller Shield
https://www.electronics-lab.com/diy-arduino-rgb-led-controller-shield/
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 color independently by changing the duty […]
DIY Voltmeter using a simple voltage sensor and Arduino Uno and a Nokia 5110 LCD
https://www.electronics-lab.com/diy-voltmeter-using-simple-voltage-sensor-arduino-uno-nokia-5110-lcd/
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 our voltage sources, […]
