In this tutorial we are going to read some values from Arduino and displaying in on an Analog meter using Processing.
Β
As you can see here I have connected a potentiometer to Arduino and when I rotate the knob the change in resistance will be measured by Arduino and the values will be read by our processing program and display it in the analog meter.
Β
Only for simplicity I connected potentiometer, we can connect any sensors like a piezo, fingerprint, load cell, pressure sensor, heartbeat sensor, etc.. and display its result using processing.
gracias me sirvio mucho
