Previously I have blogged about using relays with an Arduino, and SainSmart relays specifically. A while back I received a 4 relay, and a 8 relay board, and both of them used negative logic, i.e. a LOW activated them, and

This project is a bit more complicated than some we have done recently. Adafruit makes a very nice LCD Keypad Shield, that unlike most of the others, has a 2 wire I2C interface (covers the lcd and the keypad), and

Many of our projects require logging the sensor data to a sd card, and some of those projects require a time / date stamp. We used to use discrete modules to do this, but Adafruit has a very nice Proto

For years we have been receiving these wonderful blue Arduino boards with Arduino.cc printed on the back. Imagine my surprise, when this time, it’s a green (teal) board and says ARDUINO.ORG on the back. Not only that, but it comes

Last week I built a Proto Screw Shield from Sparkfun. Although it’s a very nice piece, and easily assembled, I received one from Adafruit today that I believe to be a bit better. First of all, It’s REV 3 compliant, which
