Running Rust Programs on <span>Arduino Uno</span> A long time ago, to run Rust on Arduino, you had to install a specially modified Rust compiler that supports AVR: rust-avr. A month ago, rust-avr has been merged into the Rust master branch, which means you can play with Arduino under Nightly now. It also includes a new … Read more
Click the “Mushroom Cloud Creation” above to follow us! 1. Overview Hello World is the first lesson in learning any programming language, but in Arduino learning, our Hello World is called Blink. What does Blink mean? It means to flash. In fact, Blink is a program that lights up the onboard LED on the Arduino … Read more
Effect Achieved Pour water into the cup, and the change in water level can be observed through the serial monitor showing the value changes output by the water level sensor. In this experiment, tap water was used. It was found that in dry conditions (when not submerged in water), the resistance value is at its … Read more
This project develops a multifunctional unmanned boat controlled by the Arduino Uno board and ESP8266 module, allowing the boat to move forward and turn left or right. Hardware Preparation As seen in the flowchart, the multifunctional unmanned boat receives operational instructions from a mobile app. After receiving the command, the Arduino board sends signals to … Read more

Remember to follow me so you don’t lose track! In the previous live stream, we systematically introduced the Arduino UNO board. Considering that some friends missed this live session, I am now sharing the live video with everyone as follows: The video mainly introduces various interfaces, main chips, pins (digital and analog) that programmers should … Read more
Basic Requirements: Use the built-in ADC of the Arduino Uno to measure voltage input and output it to the serial port. Use the “Serial Plotter” on the PC side to view the corresponding waveform. Advanced Requirements (Software): Understand the basic functions and working principles of an oscilloscope. Use timer interrupts for sampling to ensure a … Read more
