An if statement allows you to choose between two discrete options, TRUE or FALSE. When there are more than two options, you can use multiple if statements, or you can use the switch statement. Switch allows you to choose between several discrete options. This guide demonstrates how to utilize a switch to activate one of […]

Arduino is not restricted to receiving data from sensors only; you have the ability to also link a full-size PS/2 keyboard and type as you would on a traditional computer. Attaching a keyboard to an Arduino may seem strange (since it’s a small microcontroller), however, it should be noted that an Arduino has greater processing
With the Mouse library, an Arduino Leonardo, Micro, or Due can manipulate the onscreen cursor of a computer. This specific instance involves the use of five pushbuttons to control the movement of the cursor on the screen. Four buttons control direction (up, down, left, right) and one activates a left mouse click. Cursor movement on
Interfacing Electronic Circuits to Arduino In this tutorial, I show how to link an Arduino to an ARINC 429 transceiver as an illustration of interfacing an Arduino with circuits, so you can use these methods for your projects. The ARINC 429 bus is commonly utilized for computer to computer communications on aircraft. The ARINC 429

Amazon’s Alexa is cool. USB fans are cool. Alexa enabled USB fan, even cooler. This fan turns on with a voice command to an Amazon Alexa device, “Alexa, turn [insert your name here]’s fan on”. The fan is also set to turn off automatically after 45minutes (adjustable through code). The weather has been hot lately
Although there are many garage door projects on Instructable using Arduinos, I needed/wanted something different. Last year, we had a warm summer and when I would come home after work, I would leave the garage door open about 1 foot so it could cool off. The trouble was that several nights I left the garage
Update: check out the RFToy — an easy-to-use standalone gadget to control remote power sockets. Also, support for remote power sockets have been added to OpenSprinkler firmware 2.1.1. For a while I’ve been looking for a way to switch household power line (110V) devices. One of the simplest options is to use a relay that is connected to

This project will add tweeting capabilities to the GE 45142 Choice-Alert Wireless Control Center Alarm system. The alarm system allows you to connect up to 16 different sensors across 4 zones and with the addition of the Arduino powered Alarming Tweet you can enable it to keep you informed of it’s status anytime anywhere. Originally
I had been looking for a cheap alternative to some of the Arduino Bluetooth devices I’d seen, which in my opinion are overpriced. Redbear’s Mini: $39.95 (Note: This is a uC and BLE combo). Redbear’s Uno Shield: $29.95 BLEDuino: $19.95 (if part of Kickstarter) Bluegiga Shield: $69.95 After seeing these, I thought I’d try to

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,
