Dagu mini driver alternative programs.

For those who bought the Dagu robot, these are the alternative program to start with .
You can find more information at Dawn robotics blog .

Demo program for a car controlled by Dagu mini driver.
You can actually turn this program into a line tracker using IR sensor like TCRT5000,
or using sonar sensor to detect walls.
Hope this make a good start. If you need, change the motor speed as needed.

// Demo program for the Dagu Arduino Mini Driver. Uses dead reckoning // to try to drive a robot in a square   const int LEFT_MOTOR_DIR_PIN = 7; const int LEFT_MOTOR_PWM_PIN = 9; const int RIGHT_MOTOR_DIR_PIN = 8; const int RIGHT_MOTOR_PWM_PIN = 10;   const int DRIVE_FORWARD_TIME_MS = 1500; const int TURN_TIME_MS = 2000;   //---------------------------------------------------------- void setup() {     // Setup the pins     pinMode( LEFT_MOTOR_DIR_PIN, OUTPUT );     pinMode( LEFT_MOTOR_PWM_PIN, OUTPUT );     pinMode( RIGHT_MOTOR_DIR_PIN, OUTPUT );     pinMode( RIGHT_MOTOR_PWM_PIN, OUTPUT ); }   //---------------------------------------------------------- void loop() {     // Drive forwards at 100%     // Try changing the maximum value to 100 if your car is running too fast.       digitalWrite( LEFT_MOTOR_DIR_PIN, HIGH );     digitalWrite( RIGHT_MOTOR_DIR_PIN, HIGH );     analogWrite( LEFT_MOTOR_PWM_PIN, 255 );     analogWrite( RIGHT_MOTOR_PWM_PIN, 255 );     delay( DRIVE_FORWARD_TIME_MS );       // Turn right at 50%. Stop right motor on left motor.     // you can change the value from 128 to lower.      digitalWrite( LEFT_MOTOR_DIR_PIN, HIGH );     digitalWrite( RIGHT_MOTOR_DIR_PIN, LOW );     analogWrite( LEFT_MOTOR_PWM_PIN, 128 );     analogWrite( RIGHT_MOTOR_PWM_PIN, 128 );     delay( TURN_TIME_MS ); With these, you can easily start you Dagu vehicle. You can check out Dawn robotics for their program with Bluetooth, which could be harder for some to understand.
