In this class we will be using the Sunfounder Raspberry Pi Pico W Keppler Kit. It will make things a lot easier if we are working on identical hardware. the link below is to amazon, and is for the identical hardware I will be using in this entire class.
In this video, I will show you how to work with PIO state machines and machine code to get precise timing control for accurate distance measurements with the HC-SR04 Ultrasonic sensor. I will show you how to hook up the circuit and how you can program the state machines for maximum accuracy. Then I will show how to include a SSD1306 OLED display for creating a portable distance sensor Enjoy!
