0 comments In the last episode, I spend time figuring out how to detect and respond to the row and column strobes. Here’s the short list of tasks: Hook up the shift registers to the arduino and write some code to make sure that I knew how to drive them. Write some timer code to handle the […]
0 comments I’m building a project using non-addressable RGB strip, where all of the LEDs in the strip are connected in parallel and are therefore the same color. I thought it might be a bit useful to talk about the techniques that I’m using in the software, and some of the options & tradeoffs that exist. The […]
0 comments This afternoon I got my information radiator/team status board finished. Here’s what the completed Arduino shield looks like: On the front, we have four seven-segment LED digits, where the digits are 1” tall. I considered using a pre-built shield that displays digits but the ones I saw all used pretty tiny digits. I would have […]
0 comments I picked up Netduino a couple of months ago but didn’t find any time to play with it until the holidays. As somebody who has done a few projects with microcontrollers (most recently Atmel AVRs) and as a C# design team member, I found it to be an intriguing idea – to be able to […]
