Prerequisite

This example is to control a servo motor and DC motor using bluetooth.

To implement this function, you need a Platform board, Easy Module Shield V1, Bluetooth module, DC jack, 5V DC Power Supply.

Below are what we used.

  • WIZwiki-W7500 from WIZnet (Platform board)
  • Arduino Motor Shield
  • Easy Module Shield(Not mandatory)
  • HC-05 bluetooth module
  • Servo motor(DM-S0300D)
  • DC motor(5V)
  • DC jack
  • 5V DC Power Supply
