Blinker car

Adopting the mainstream 6-axis sensor mpu6050 modular design to reduce the size of the board. It was the first time I bought a motor and a tire and I had no experience. I didn’t know until I bought it that it couldn’t be installed. The tire shaft was too small, so I had no choice but to use a soldering iron to enlarge the shaft hole. point. The headlights are controlled by Blinker, which can be controlled remotely via Bluetooth or WiFi (currently only forward and backward, the code is being debugged). Through this actual combat, I found that there are too many problems. 1. I didn’t read the MCU documentation carefully! Some pins of esp32 are not suitable as control pins, which will cause the esp32 to fail to start (infinite restart), such as CLK20pin.

2. Failure to check carefully before powering on caused the cp2102 serial port chip of the esp32 to burn out. This problem is too easy to make. The charging and discharging ic also failed to pay attention to the boost module and did not adjust it to 5v. Instead, the default 12v was used, causing the ic to directly Smoke![VID_20210418_135158.mp4]()
