Setup

  • Items needed:
    • PC or Laptop
    • Raspberry Pi (I used model 2B)
    • ADS1015 12bit ADC converter (if you use 1115 which is 16bit, there will be slight changes)
      • Breadbord, wires, resistors
      • Adafruit assembled Pi T-Cobbler Plus - GPIO Breakout (Optional)
  • Circuit setup
    • Refer to fritzing diagrams in schematics folder
  • Configuration
    • SSH, VNC or anyother method of communication enabled between the Raspberry PI and the user PC
      • My case was
        • Laptop with Ubuntu 16.04 LTS
        • Raspberry PI 2B with Raspbian Jessie release 2017-01-11-raspbian-jessie.img
        • SSH communication through ethernet cable
  • Deployment instructions
    • As per the schematics folder
      • Connect Raspberry with Adafruit T-Cobbler
      • Connect T-Cobbler onto the breadboard
      • Connect ADS1015 onto the breadboard
      • Do the wirings as described in the schematics folder
      • In the circuit diagram I made a note about the location of the UNKNOWN resistor
