Arduinos are perfect for development: you just plug them into a USB port and all the old hassles of dealing with AVR chips (crystals for clocking, hooking up comm lines, regulating power…) are handled for you. But sometimes you need to roll your own custom solution. In real life–whether because of size, cost or power…
As mentioned before, I love me some LEDs and have a particular fondness for the MegaBrites, powerful RGB modules that are easy to chain together. The only issue I encountered in using the hardware was with SPI support or, more specifically, lack thereof. On certain Arduino’s, like the very tiny Digispark, there is no hardware…
Druid4Arduino–an automatic/configuration-free graphical user interface for Arduino projects–has just been released as free software (under the GPL), with binary programs available for Windows and Linux. This software enables you to provide a GUI for your device or project without having to spend any time programming windows and buttons. You need only include the SerialUI…
Quick word to mention that SerialUI version 1.4 has been released. From the programming perspective, this update involves only a single change (the addition of a showEnterNumericDataPrompt() method, to provide more precise feedback than always using showEnterDataPrompt()). The most important thing is that the library now supports a mode specifically designed to aid interaction with…
A few months ago, I funded my first kickstarter project for production of the Digispark: a tiny (less than a square inch) Arduino-compatible device based on the AVR ATtiny85. Plugged-in Digispark Though I received the occasional progress update email, I pretty much forgot about the Digispark. Until last week, that is, when I received a…
