In Experiment 6, we used Arduino to measure the voltage at port A5. By applying Ohm’s Law I = U / R, we can calculate the current flowing through a known resistor by measuring the voltage across it.In this experiment, we will learn how to use Arduino to create a simple current meter.1. Experiment Materials … Read more
Exploring the World of Sensors: A Fascinating Journey of Experiments Based on Arduino In today’s rapidly advancing technology, sensors serve as the “tentacles” that perceive the world, widely used across various fields. Are you curious about how these sensors work? Do you want to experience their wonders firsthand? Today, let us use the Arduino development … Read more
The running light is a common electronic display effect characterized by multiple LED lights (or other light sources) lighting up and extinguishing in sequence, creating a dynamic visual effect similar to “flowing water” or “waves.” The running light experiment is simple and intuitive, making it a classic project for learning Arduino programming.1. Experiment Materials 1. … Read more

Recently, the microcontroller obtained a coil and conducted a coil induction experiment using ESP32 and Phyphox. Due to the small inductance of the coil, the induction phenomenon was not very obvious, but the technical solution has been validated. If a coil with more turns and an iron core can be obtained, the experimental effect should … Read more
Experimental Scenario 1 Introduction Recently, while reviewing exam papers, I encountered an innovative question based on photoresistors. Inspired by this, I decided to design a clever experiment using Phyphox and ESP32 to see if I could measure my own heart rate. 2 Design Idea Utilizing the combination of Phyphox and ESP32 to measure the resistance … Read more
