    Speed measurement of a small DC motor using myDAQ and LabVIEW

    Hey guys I'm trying to measure the speed of a small DC motor using a rotary encoder and an OPTO sensor, and counter input on myDAQ. Here's my circuit on the breadboard. The Collector pin of the transistor is connected to the DIO1 port of the myDAQ. And here's the LabVIEW code. On the...
