Programming:
Troubleshooting:
1. Check IR sensor for color detection. black (LED off) & white (LED on) by changing the sensitivity using potentiometer from IR sensor.
2. If ultrasonic cannot detect object, then increase the value of "MAX_DISTANCE" from Arduino line 3 & 4.
3. If motor run different direction, exchange connection from IN1 & IN2 (IN3 & IN4) jumper cable pin.
Note:
1. Don't overuse your LiPo battery until less than 11.1V.
