On her blog, Dustyn Roberts presents her own experience on current sensing for controlling DC electric motors with an Arduino board and an Arduino Motor Shield. This shield, based on a L298 H-bridge, provides two current sensing pins to the user, which can be used to measure the instantaneous current absorpion by each H-bridge. After […]
Hardware Hacking guys propose this quick tutorial on how to improve the accuracy of Arduino’s ADC readings, by measuring the actual voltage rail used to supply the onboard microcontroller. At a glance, this can be done by measuring the internal 1.1V reference voltage (it is available for ATMega 168 and ATMega 328 only) and, then, by […]
There are many Quadrotor Projects out there. But, they require a hobbyist to deal with the Frame Designing (Mechanical), a bit of Microcontroller knowledge as well as dealing with the Motor Control (Power Electronics). You may purchase a commercial Radio and a readymade Kit for flying. But, to Do-It-Yourself, is an achievement in itself. Here is […]
Many solutions exist for publishing data coming from Arduino boards on the web. Bangon Kali, in his detailed tutorial, proposes his novel approach, which makes use of several widespread and open-source technologies, such as Node.JS, jQuery and Apache: Using the USB, the Arduino Board is connected to the PC serially to a certain COM port which the […]
Nice tutorial about how to make pencil drawings reactive to touch using just pencil, some resistors, paperclips, wire, Arduino and tape.
In this instructable, Dustin Andrews shows how to make a custom Arduino board, equipped with a lcd, a buzzer and a solid enclosure. Dustin’s goal has been to design a rugged Arduino version, that can be employed “as is” in many practical project, in place of a less solid breadboard-based solution. The project is released […]
Ever wanted to see how much electricity your next project is consuming? Look no further; this Instructable will guide you about how you can, too, make a device to monitor the same. This project was developed by Steve Spence of Arduinotronics with input from forum members at the Yahoo Group – Arduino Home and The Arduino Forum. Steve […]
Going to buy a new Wireless Controller for your next Robotics project. Why buy a new one when you can Do-It-Yourself? All you need is an Arduino, an old Joystick with a Gameport (15-pin connector) and a pair of Series 1 xBee Modules. The explanation of the xBee Configuration and the xBee Packet Description is very […]
Makers need to familiarize themselves with the core concepts and the theory involved in creating applications such as Motion Sensing and Face Tracking. As the technology is churning out new hardware day and night, DIYers need to work hard to keep up and always be in touch with the latest technology around them. For example, […]
Lucid dream is a state in which you can control what you dream. Be it winning a million bucks worth lottery, or dating your favorite cine star, it is possible to control your dreams using these DIY goggles! Simple to build and a nice weekend hack for the bored, these goggles are pretty cost effective […]
