How To Use?

If you have any questions，such as how to install the development board, how to download the code.

Please refer to :Get Started with MicroPython on Raspberry Pi Pico

V1.1 Project

project-1-display_led_button.py

Control onboard leds via buttons. And display status on TFT screen. Don't need any module

project-2-leveling.py

Simple graphic level, read inclination angle with MPU6050. Insert MaBee MPU6050 to CN3

project-3-adc_display.py

The voltage value of the read slide potentimeter is displayed on the screen Insert MaBee Slide Potentimeter to CN5

project-4-weather_8266.py

Connect to WiFi through ESP8266 module and get the weather. Insert MaBee 8266 to CN1 API from "api.openweathermap.org" is not stable, please try more and pay attention to the serial port information.

project-5-temperature .py

The temperature and humidity are obtained through DHT11 and displayed on the screen Insert MaBee DHT11 to CN6

project-6-ir_distance.py

The distance is captured by a Sharpir sensor and displayed on the screen Insert SharpIR to CN5

project-6-HC-SR04_distance.py

The distance is captured by a HC-SR04 Ultra sensor and displayed on the screen Insert SharpIR to CN6

project-7-servo_control.py

Use button control servo and MaBee relay Insert Servo to CN6 Insert MaBee Relay to CN5

project-8-ws2812.py

Insert WS2812 to CN6
