Using VMeter and Arduino to control a Fan, Servo Motors, and Read Analog Input
Using an Arduino and USB Host shield, you can use the VMeter to visualize and control physical knobs and motors.
Things you'll need
- Arduino
- USB Host Shield
- The USB Host shield libraries (available at above link)
- Arduino code (note, this code works on an original arduino and USB Host Shield, you might need to tweak things if you're using a new model of either. Email us if you need any help).
- Servos
- DC Motor
- Potentiometer (to test analog input)
What the code does
Depending on what parts of the code you leave commented or uncommented, it can do the following:
- (arduino --> VMeter) read analog input (voltage) and display the output on the VMeter as a column
- (VMeter --> arduino) read the position and or pressure, and use this to control either a DC motor (analogWrite()) or Servo Motors.
Note(s)
- When you test out your USB Host shield, first run the descriptors test code (Arduino --> examples --> USB) to make sure you can initialize the VMeter.
