Hi! One of my mentors has purchased an XRP kit for one of our projects. We are planning on buying more of these kits but currently, the ultrasonic distance sensor and line sensor don’t work. The motors, servo, and led all work. We have tried to replace the batteries and run the verification code among other things, but we haven’t been able to get appropriate values from them. Please let me know if anyone has any insight into why the sensors are not working.
Thank you!
Hi there,
Please unplug the 2 sensors and look closely inside the connectors to see if any pins inside are bent like the image below. This can happen if the connectors are inserted at an angle instead of straight.
If so, you can unbend the pins with a pair of tweezers, just be careful to not fatigue the metal, otherwise the pins can break.
Also, verify that the wire colors are correct on the 2 sensors:
Hope this helps!
