I’ve assembled a Picar-x-2.0 with robot hat v4 and a pi 5. I am having problems with calibration of the servos, so I reviewed some of the videos concerning the servos not zeroing, that lead to what I believe maybe another problem. On the completion of start up there should be an audible sound, I do not any sound from the robot. During assembly I did zero the servos. I have tried the greyscale calibration with the same negative result, but the sound test works. During the flash-up the only lights visible are the power (green) batteries level (orange) and the pi 5 (green). But I’m thinking there is something wrong with the HAT.
It is recommended that you provide us with a video of the issue for confirmation, which will help us analyze and resolve the problem.
If you are using Python to control the PiCar-X, the product’s speaker will not make any sound simply upon starting up the PiCar-X. It will only produce sound when you run the sound-related example code.
Grayscale calibration failure?
It is advised to check if the wiring for the grayscale module is correct.
Please refer to the assembly sheet to confirm the wiring positions.
After confirming the module wiring is correct, run the grayscale calibration example and observe the calibration result. Please provide us with a screenshot of the information.
