CONTROL OF SERVO AND STEPPER MOTORS USING TOUCHSCREEN

Individual Project Requirements:

 

To build a circuit with the Arduino Pro Mini to control a stepper motor and a RC servo motor. A touch screen needs to be used to enter a position command in degrees that the motors will rotate.  A rotation command needs to be prompted on the LCD display, and the number entered should be echoed at the LCD.  The microcontroller should be programmed in basic C++ language.

 

  • On start, prompt the user to select which motor to drive (servo  or stepper);

  • Direction should be prompted as CW/CCW;

  • After holding position for “n” seconds, the motor returns to the zero position;

  • Program returns to the start prompt.

 

Parts Used: 

 

  • Solderless breadboard;

  • Arduino Pro Mini microcontroller;

  • FTDI USB programming interface;

  • 2x16 Serial LCD display;

  • Touch screen and touch screen connector;

  • Stepper motor;

  • Stepper motor driver;

  • RC servo motor;

  • Hook-up wires;

  • Powerful power supply.
