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.

ReplyDeleteDieser Artikel über den „schlüsselnotdienst münchen“ in München hat mir die Augen geöffnet. Mir war bisher nie klar, wie wichtig es ist, Zugang zu Notfall-Schlosserdiensten zu haben. Es wäre großartig, wenn der Artikel auf einige reale Szenarien eingehen könnte, in denen diese Dienste das Leben der Menschen erheblich verändert haben.
