Recently, I found a very magical device in my desk drawer. Upon closer inspection, it turned out to be an ultrasonic distance sensor from a kit given during a Maker Education Instructor training in Zhengzhou back in 2016. This device has been lying in the drawer for nearly 5 years. Is it still usable? I … Read more
Communication Methods Between Devices Generally, the communication methods between devices can be divided into two types: parallel communication and serial communication. The differences between parallel and serial communication are shown in the table below. Classification of Serial Communication 1. According to the data transmission direction, it can be divided into: Simplex: Data transmission only supports … Read more
Recently, the microcontroller enthusiast has been researching how to use light-emitting diodes (LEDs) to replace the dot timing method to optimize kinematics experiments. Initially, self-flashing LEDs were used, but due to the equal duration of the flashing and dimming, noticeable motion blur was produced. To avoid motion blur, the enthusiast used the ESP32 development board … Read more
1 Introduction Recently, during the joint examination, there was a question about measuring the electromotive force (EMF) and internal resistance of a power source using the voltage-resistance method. Considering the authenticity of this experimental background, we validated the experiment using ESP32 and Phyphox. 2 Question Review and Reference Analysis 3 Experimental Validation In this validation … Read more
Recently, we conducted an electromagnetic oscillation experiment using Phyphox, ESP32, and ADS1115. The results were very satisfactory, and we witnessed the oscillation of current in the LC oscillation circuit composed of the coil and capacitor. Following the diagram, we connected the ESP32 and ADS1115 using DuPont wires. The wiring was quite complex due to the … Read more
Experimental Environment Recently, the microcontroller enthusiast used ESP32 and Phyphox to plot the I-V characteristics of a solar panel. The experimental circuit is simple to set up, with automatic data collection and automatic graphing, saving time and effort while yielding good results. What used to take dozens of minutes to complete can now be done … Read more
Experimental Scene and Circuit Connection Recently, I found online that a teacher published a paper in a journal, using the voltammetry method to measure the resistance of a photoresistor while measuring light intensity with a light sensor, then plotting the relationship curve of photoresistor resistance and light intensity in a spreadsheet. The steps are cumbersome … Read more
