My name is Dharsan: I am a student at WSU as well as one of the new Product Marketing Engineering Interns at Digilent. I am working with LabVIEW and the NI myRIO to create projects that help teach people how to use LabVIEW. This week, I’ve been working on a project that controls fan speed based on a temperature reading. An in-depth description of this can be found on instructables.com here.
In the future, I will be working with LabVIEW and the chipKIT WF32 to create more small projects like this.
In this project I created two simple circuits: a voltage divider to measure the voltage change across the thermistor with changes in temperature, and a transistor circuit that switches power to the fan. Then, using LabVIEW, a myRIO, and a myProto, I created three different fan speeds depending on the thermistor voltage.
Please let me know what you think or if you have any questions.
