Serial communication methods such as ART, SPI, and I2C are very common in embedded development. The underlying principles of these communications are not difficult, but many beginners struggle to understand them. Today, I will share some common underlying data transmission principles of these communication methods. 1UART Serial Port UART: Universal Asynchronous Receiver/Transmitter. The UART serial … Read more
Popularizing knowledge of digital and analog electronics, promoting science and education for national prosperity. In this issue, Maker e Workshop teaches everyone how to create an infrared remote control switch circuit to control household lights, fans, garage doors, etc., making it convenient and practical. When it gets cold, we can lie in bed directly, or … Read more
Infrared is a type of electromagnetic wave with a wavelength longer than red light. Since it exceeds the range visible to the human eye, it cannot be seen by humans; however, sensors can detect it, with wavelengths generally between 760nm and 400nm. We can utilize this to create an infrared controller. Infrared remote controls are … Read more
Infrared Thermometer Technical Principles All objects with temperatures above zero degrees (-273.15°C) continuously emit infrared energy into the surrounding space. Their radiation characteristics, the magnitude of radiation energy, wavelength distribution, etc., are closely related to the object’s surface temperature. Conversely, by measuring the infrared energy emitted by the object itself, we can accurately determine its … Read more
