【Smart Car】Thomas small car 1094966A

The control panel uses ATMEGA 328P NRF24L01P 2.4G communication module to connect and control with the remote control. It is also equipped with E103-W01 WIFI module, which can be connected to the network for adjustment or control...

The car uses an Arduino microcontroller as the main control.

It uses four 370 motors as power and is equipped with 65mm rubber wheels. Two rz7886 motor driver ICs are used on the control board to drive the car.

Use remote control to control and communicate through nrf24l01 module. There are three buttons on the board, and you can switch the control mode through button 1. Currently, only a simple 2.4g control method is written.

I originally planned to use pwm for speed adjustment, but I don't know why. It may be a small problem with the control board. Modules welded with perforated boards before would not have this problem. When pwm is started, the nrf24l01 module will stop receiving data, and the remote control and control board will be disconnected. Therefore, the speed adjustment function will not be used for the time being.

Since time is a bit tight recently, I didn't have time to write the program in detail. I planned to play with the WiFi module before, but now the WiFi is idle. The headlight extension has not yet been installed. The submission time is coming, and I can install it when I have free time later.

There is a small problem with this version of the remote control. There is a slight glitch. The drawing has been deleted and replaced with a new one. But the new board hasn't been finished yet, and the time has almost expired. Just make do with this board.

I ran out of potentiometers on hand and didn't install them on the remote control.
