1*Linear/Slide Potentiometer of Linker Kit for pcDuino/Arduino

Some wires[/vc_column_text][/vc_tab][vc_tab title=”Connection diagram” tab_id=”1389153395-2-55″][vc_column_text]

Potentiometer connects to pcDuino’s A2/GND/5VCC pins

git clone https://github.com/pcduino/python-pcduino.git

Next we creat a adc_test file under Samples folder, and code is as below:

  1. import time
  2. from adc import analog_read
  4. def delay(ms):
  5.     time.sleep(1.0*ms/1000)
  7. def setup():
  8.                 print “read channel ADC2 value ,the V-REF = 3.3V”
  9.                 delay(3000)
  11. def loop():
  12.     while(1):
  13.         value = analog_read(2)
  14.         voltage = (value * 3.3)/4096
  15.         print (“value =  %4d”%value)
  16.         print (“voltage =  %4.3f  V” %voltage)
  17.         delay(100)
  19. def main():
  20.     setup()
  21.     loop()
  23. main()

Save and compile

  1. python adc_test.py

Display output, adjust the potentiometer, the numerical changes.
