The Arduino UNO R4 Minima and Arduino UNO R4 WiFi that were released a few months ago are now officially available. Yesterday, they were officially launched on the Arduino Store, and the new version brings many possibilities to our DIY world, upgrading from the previous 8-bit MCU to a 32-bit Arm Cortex-M4, with memory increased … Read more
This experiment demonstrates how to control 6 servos simultaneously, which is the maximum number of servos that can be controlled by an Arduino Uno without using additional servo driver boards. It is important to note that the pins on the Arduino Uno that can connect to servos need to be PWM-enabled, which are the pins … Read more

Running Rust Programs on Arduino Uno 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

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
