Embedded systems frequently use HD44780-type LCD displays as it is considered the most popular alphanumeric display controller. The interface comprises at least 14 pins: eight for data, three for control (EN, WR, RS), two for power supply (Vdd, Vss), and one for contrast (Vre). Configured in 8-bit mode, it requires at least 10 I/O lines […]

I am teaching a robotics course in my kids high school (Rambam Mesivta in Lawrence, NY). I was looking for a cost effective way to teach them about the priciples of robotics without spending an arm and a leg, and getting them excited about the prospects of hacking hardware and teach them how to interface […]

[OoB] Shooting paintball maker with relay, Arduino and .NET WinForms My first Arduino based project was Sonar with C#, JS and HTML5. Now I continue the “Out of Boredom” series with a setup that allows firing a paintball marker (gun) with a command sent from a computer 🙂 This time software stack is simpler – […]

This project is a relatively straightforward and simple DIY music board. The Dot Matrix Board will allow any aged person to create their own music and beats. All you need to have is an understanding of Arduino and circuitry. Step 1: Gather Parts Needed Step 2: Assemble the Board To begin building the board on […]

what: a 5*5 rgb led matrix, made with arduino and lpd6803 based leds from adafruit. with an pir sensor, it goes on if it detects movements and a ir distace sensor, 1 animation shows the distance you have from the sensor :). why: because its beautiful and cool 😉 my spelling: well, sorry if i […]

It can even be interactive based on the programming.Parts: ($7.60) 16 Digit TM1640 based display Dealextreme.com SKU: 104311 http://www.dealextreme.com/p/jy-mcu-16x-digital-tube-yellow-led-module-104311 ($2.50) Atmel ATtiny85 Digikey PN: ATTINY85-20PU-ND($1.73) Extra long female header pins Digikey PN: SAM1209-12-ND –  I got longer sections, as I […]

Andrew O’Malley, an amazingly creative maker, created this fanstastic Open Source Arduino-based clock that can display the time in many different ways: if not enough, one can also add his own personal animation. Compared to other clocks based on Arduino, this one has two distinctive features: a single board with the ATmega 328P chip plus […]

This instructable covers the assembly and use of a Tiny Wearable LED kit.  The kit is useable immediately but is desigend to be hackable and can be reprogrammed to your liking using an ISP programmer or Arduino board and the Arduino IDE. There are not too many tiny implementations of microcontrollers.  The Arduino lillypad is […]

BLACKSBURG, Va., Jan. 22, 2014 – A Virginia Tech research team has developed a battery that runs on sugar and has an unmatched energy density, a development that could replace conventional batteries with ones that are cheaper, refillable, and biodegradable. The findings from Y.H. Percival Zhang, an associate professor of  biological systems engineering in the […]

WARNING: THE FOLLOWING PROJECT USES LASERS. PLEASE CHECK YOUR LOCAL AREA RULES ABOUT LASER USAGE. PLEASE BE CAREFUL AS HIGH POWERED LASERS CAN ALSO DAMAGE YOUR EYES. I CANNOT BE HELD RESPONSIBLE FOR ANY CONSEQUENCES OF USE. Given the opportunity to use one of the Intel Galileo boards, we wanted to build something that would […]
