PaulSS @ instructables.com shows us  how to build a menu for a LCD/button shield: While working on a new Instructable (coming soon) I had decided to use an Arduino Uno with an LCD/button shield I purchased off of AliExpress. It's a knockoff of the DFRobot Shield. I knew that I...

A few months ago, with version 1.6.6, the Arduino IDE introduced a great new feature. It is called Serial Plotter and you can find it in your Arduino IDE under the tools menu. Using the Serial Plotter we can graph the output of our Arduino project in real time. A tutorial describing...

In this instructable, we will be building a laser guided tripwire alarm system using a SainSmart Leonardo R3 development board. Arduino - Laser Tripwire Alarm System -...

TheSuperSewcio @ instructables.com shows us how to control a servo motor in high precision using Arduino: In many project like CNC machines people use stepper motors. They are probably always more expensive than servos. They can rotate 360°, 1 step = 1,8° (mostly). Servos can...

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...

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...
