Arduino M0 Pro The Arduino M0 Pro —initially called Zero Pro— board is a major revision of the Arduino line as it is the first Arduino board to feature a debugger. The board is designed around the 32-bit ARM Cortex-M0+ SAMD21 from Atmel and built in Italy. The EDBG chip from Atmel provides the debugging capabilities. The SAMD21 MCU features […]

I have been collecting data from Raleigh’s trails and parks for the last couple years.  My primary platform has been a custom Arduino board I developed for low-cost (hey, these things may get damaged or stolen) and long battery life.  I wanted a connected sensor to provide current data and, after looking at various technologies, […]

More VideoBlasting So why didn’t the TV out library reach any higher resolution than 160×100? The answer is simple. They did not use any hardware on chip to push the pixels out. If you use the SPI to push the pixel you will gain an immediate 1:1 in pixel speed The SPI push out data […]

Introduction This is my first Arduino project. My work was inspired by several maker projects that created Persistence of Vision Displays [2,3,4]. Persistence of vision (POV) refers to the optical illusion whereby multiple discrete images blend into a single image in the human mind and believed to be the explanation for motion perception in cinema and animated films [1]. The projects […]

Today, we are going to build a circuit to program an ATtiny85 with our Arduino. Supplies We are going to need the following: Some jumper wires 1 x 10 micro farad capacitor The ATtiny85 Chip A breadboard An Arduino For Extra visual’s (that are not really required) I’m going to add: 3 LED’s 1 x […]

I like cheap electronics for playing. Cheap is good for budget conscious hobbyists and China is delivering lots of toys for playing – one being the inexpensive “mono” OLED displays.  The single-color displays often come in a dual-color implementation where the top row of pixels are one color and the remaining majority of the lower […]

Stand out from the crowd with this unabashedly ostentatious excuse for a wallet. It’s got plenty of space, RGB lights, and you can even put your name on it for added vanity. Interested? Keep reading! In the files section of this build you can find two things: a Fusion archive and some STL files. If […]

Small enough to slip in a mint tin, yet loud enough to be heard across a house at only a few dollars per unit. A nice combination for a pretty good prank! Let’s dive in! Step One: The Circuit You can purchase the printed circuit board from OSH Park using the link in the parts […]

This would be the continuation of my previous project Programming ATtiny85 with Arduino Uno. Now with cheaper ATtiny85 in place I was looking for cheaper ways to transmit the sensor data. Which brought me to nRF24L01+ a cheap, low power RF transceiver. This seemed to be the better solution for me. But there was one […]

I came pretty close to calling this one “Magnets, How do they work?” But I thought that might confuse more than it would amuse. All jokes aside, hall effect sensors are pretty cool, and also pretty simple to use, but there are a few types you may not know about and I figured it would […]
