This project slightly modifies the Google Android sample app called “Bluetooth Chat” so you can type a message in the Android app and that same message will appear on an LCD attached to an Arduino Uno. Functionality: Android talks to Arduino 1. Run the Android “Bluetooth Chat” sample app (after we modify the app in

I’m going to show you how to use your Arduino to control up to 12 servos at once with minimal jitter. Using a simple serial interface you can control the position of up to 12 servo channels. Up to 10 snapshot positions can be saved and played back at any time. Start up values for

If you need an Arduino to shut off from within your Sketch, this is the solution. We will explore wiring the Pololu Pushbutton Power Switch, programming the Arduino to shut off the power, and making the unit “power on” only. The Pololu Pushbutton Power Switch comes in two versions – the SV version geared towards

I had one remote controlled project that needed an Arduino running 24/7 but I didn’t want to leave my $32 Arduino UNO, so I decided to buy some pieces and created my own Arduino. The most important part was buying the microcontroller. These were my options: ATMega328P-PU with Optiboot ~ $5.50 (Sparkfun) / $5.19 (Digikey)
Burning the Bootloader on ATMega328 using Arduino UNO as ISP Continue Reading
I am presenting a compact design of a stripboard Arduino board (DIYduino) that includes a 2A motor driver and has additionally the functionality of a sensor shield. The 2-channel version cost approximately $29.43 and is more affordable compared to $39.00 for a commercially available system consisting of an Arduino Uno, $21.50, a sensor shield, $8.50,
