Principle hardware design and source code of self-balancing car

The self-balancing car uses the power of the car model to keep the car relatively balanced, which is a dynamic balancing process. The power to maintain the balance of the car model comes from the movement of the wheels, driven by two DC motors. The hardware of the car is divided into three parts, namely the main control part, the car attitude acquisition part and the motor drive part.

PlainDAQ: Simple open source DAQ module for Raspberry Pi Pico (schematic, source code, etc.)

PlainDAQ is a simple, useful tool that adds basic precision analog functionality to your Raspberry Pi Pico board. It features a precision, low noise, low drift 12-bit 500k sps/s ADC. To match the ADC and maintain its noise and accuracy, all analog inputs are buffered and the ADC is driven by a high speed/low noise fully differential amplifier. It also has a 10-bit DAC that helps create analog outputs and waveforms.

Micro WS2812 2020 RGB LED Matrix

The Micro WS2812 2020 RGB LED Matrix is ​​a micro 25x25 mm 8x8 WS2812-2020 matrix. It's only about 1 square inch, or about a quarter the size of the United States. This micromatrix is ​​daisy chainable, meaning you can stack boards side by side while using only one data pin. Best of all, this matrix is ​​compatible with all other WS2812 related matrix codes and is open source. Despite its small stature, this matrix has everything you need, with pad connections for VCC, ground, data in, and data out. It works with 3.3 V or 5 V and is capable of outputting 16 mA per LED.
