Compact and easy to use, these encoders are great for monitoring the position of a robot wheel. I used PCINT to give me more interrupt pins, and an interrupt service routine to increment a counter for each encoder pulse. I read and reset the count to measure the distance since last time. For the Arduino robot, the 4-pin header is on the wrong side of the board. Ideally you want the sensor poking down through the baseboard and the pins pointing upwards. An unsoldered header might be better.
