(⊙o⊙)…, I am sharing Arduino-related materials again. For some, it might be incomprehensible but impressive. But who told me I have been tinkering with Arduino recently~~~~ 1. Monochrome LED Module Figure 1 Monochrome LED Module Schematic As shown in Figure 1, RED corresponds to red, GRE to green, and BLU to blue, corresponding to digital … Read more
The greatest science fiction writers probably never anticipated the invention of the internet. If the internet changed modern people, the rapidly developing Internet of Things (IoT) industry has even more to offer for the future. Whether it’s smart cities, smart homes, smart factories, or industries like construction, logistics, and public services, more and more “things” … Read more
1. Introduction to EESkill NRF24L01 Wireless Module NRF24L01 is a wireless communication chip recently produced by NORDIC, using FSK modulation and integrating NORDIC’s own Enhanced ShortBurst protocol. It can achieve point-to-point or 1-to-6 wireless communication.The wireless communication speed can reach 2M (bps).NORDIC provides the GERBER files for the communication module, which can be directly processed … Read more
↑ Click the “Digital Scientist” above to follow us Origami is an ancient art, but it can also become a part of modern engineering. Engineers can play with origami, such as folding space mirrors or cardiac stents. Ankur Mehta, a postdoctoral researcher at MIT, designed a robot that can be made using origami art at … Read more

The hardware system of the biped robot mainly includes the microcontroller minimum system circuit, PWM circuit, indicator light circuit, independent key circuit, and power supply circuit. The main design requirements for this biped robot circuit are as follows: · The microcontroller minimum system can output … Read more
Recently, I’ve been enjoying playing Need for Speed, so I bought a gaming steering wheel. After the delivery arrived, I couldn’t wait to unpack it. However, after playing for a while, I wanted to throw it away because the feel was really poor. The steering had no response when I slightly turned it, and when … Read more
With the widespread adoption of IoT modules, various “cloud” technologies are emerging, and the speed of IoT entering homes has significantly increased. As an electronics DIY enthusiast, this means having powerful tools to quickly address real household needs; all previous creative ideas can now be realized in a short time using IoT technology. Recently, my … 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
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
Enable the multi-core functionality of the ESP32 to execute tasks in parallel while setting the chip’s clock frequency and the FreeRTOS real-time system. The effect achieved in this article is shown in the GIF, where two displays execute in parallel, each using one of the ESP32’s two cores. The display of the two screens, if … Read more
