TCRT5000 IR Emitter/Sensor

I finished the carrier board for our tachometer project. This is simply the TCRT5000 IR emitter/sensor module, with the 150 ohm resistor for the IR LED, and the 10k ohm resistor for the phototransistor, as described in

I used a 3 pin header with the GVS pin standard as described in

The inexpensive breadboard from Radio Shack makes a great prototyping board when it's time to upgrade the project from a solderless breadboard. It gives the project some permanence. Solderless breadboards are good for temporary testing / design.
