Many inventions/hacks often arise out of the need to solve a problem. The Arduino mailer notifier project was no exception. My workshop is in my backyard. During the day, I am far away from my mailbox. Using two Arduinos, some cheap RF modules, and a light sensor, I was able... Read more »

Build a Wirebot

When you hear the word “wirebot,” you likely think of those cameras racing along wires above sporting events, unobtrusively capturing amazing action footage. Our wirebot will be quite a bit simpler, and a lot cheaper, however it offers quite a few cool possibilities. Some of these applications include things like... Read more »

Drive a 7-Segment LED with an Arduino

qJLSkjtrAWrCxYTo

Using the Arduino development platform you will learn how to display numbers and letters on a single 7-segment LED display. There are many ways to drive 7-segment displays, and this is a fairly simple method. However, using this method to drive even one LED 7-segment array “burns” (occupies) many of... Read more »

Replace and Re-Flash a Blown Arduino

aMC2LKotJUMBSSFD

When I first started working with microcontrollers, I had an Arduino, a few LEDs, a handful of DC motors, and very little common sense. :) I learned firsthand that if you did not read before you wired stuff up, it could be a costly mistake. However during my hardware infancy... Read more »

Arduino Drum Pad & Game

t1gTstAufKdEXVMK

This fun and easy project shows you how to create a simple input device with little more than a cheap piezo sensor, an old mousepad, and an Arduino board. Using household supplies and a few passive electrical components, you can create a basic physical-computing game input device for your Arduino. Read more »
