This example illustrates the use of the Mouse and keyboard libraries together. Five momentary switches act as directional buttons for your cursor. When a button is pressed, the cursor on your screen will move, and a keypress will be sent to the computer. Once you have the Leonardo programmed and wired up, open up your […]
Have you ever wanted to control electronics with your smartphone? The Arduino ADK (Android Development Kit) is the Arduino Mega with a built in USB host device, ready for your smartphone to be plugged in! We’ll make a simple introductory project with a few LED strips and a relay (to control the high voltages of […]
In our living room we have a small patch of drop ceiling right in the middle of the room, basically a giant piece of duct tape to cover up bad carpentry. It was constantly getting water damage from what looks like a giant hole in the ceiling above the drop tiles. After roughly a year […]
Pushbuttons or switches connect two points in a circuit when you press them. This example turns on the built-in LED on pin 13 when you press the button. image developed using Fritzing. For more circuit examples, see the Fritzing project page Connect three wires to the Arduino board. The first two, red and black, connect to the […]
Here you will learn how to create an internet controlled robot or other installation using Livebots. Livebots is a project I’m working on which consists of an easy to use website for all the robots that people can interact with through the internet. As an example I will be using a simple Arduino UNO with a LED […]
Using the Arduino Uno to program ATTINY84-20PU (Newark item # 68T3783). This Instructable shows how to use the Arduino platform to work with physically smaller processors, such as the ATtiny84 (84/44/24), ATtiny85 (85/45/25), and ATtiny2313. This example is specifically for the ATtiny84-20PU processor (Newark item # 68T3783) but can be adapted for the others boards […]
I’ve been working on a project that used a 16×2 LCD display and wanted a nice finish that also allowed me to seal against water and other liquids. I also needed impact resistance, low cost and the ability to be changed easily if worn or broken. I considered many different ideas:- 1) A full sheet […]
Objective: build a monome – a complex electronic music instrument – using easy-to-learn, inexpensive components and a process that’s so easy a kid could do it. Gist: This touchscreen music instrument is essentially 4 parts: MaKey MaKey (or Arduino) Neopixels copper tape cardboard Sound is produced in either Scratch (visual programming language for kids) or […]
The Arduino Wireless shield allows your Arduino board to communicate wirelessly using Zigbee. This documentation describes the use of the shield with the XBee 802.15.4 module (sometimes called “Series 1” to distinguish them from the Series 2 modules, although “Series 1” doesn’t appear in the official name or product description). A Simple Example You should be able […]
Whenever I go to Citi Field with my kids to see the Mets, they go crazy for the Home Run Apple.To me, the Apple is part of what makes baseball exciting for kids. Even though my kids may not watch most of the games, I still enjoy bringing them along. The Home Run Apple started […]
