The Bluetooth module is used for communication between Bluetooth devices. The most common use is for an Arduino to communicate with a smartphone via the Bluetooth module. 1. HC-06 (Slave) 1 Operating voltage: 3.3V LDO for the board, input voltage of 3.6~6V, current approximately 30mA when unpaired, about 10mA when paired. Do not exceed 7V … Read more
Understanding Analog and Digital Signals in Electronics In the previous content, we talked about digital output driver circuits. Digital quantities are a type of boolean variable that has only two states. Here, let’s discuss analog quantities. For a lamp, we can describe its two states—on and off—using digital quantities. Turning the lamp on means it … Read more
Abstract This paper designs an automatic water level control drinking machine based on the principles of light reflection and refraction. The device uses the Arduino UNO microcontroller as the control center to automatically identify different cup shapes at various heights, starting water injection automatically and stopping it when the water surface reaches 1 cm from … Read more
Today, I would like to introduce a SiFive development board, the HiFive1 RevB. It is equipped with the RISC-V Freedom E310 microcontroller and adopts the Arduino Uno “form factor” design, making it compact, which is exactly the board I wanted. My HiFive1 Development Board There is a lot of material available about RISC-V and how … Read more

Recently, a student asked me this question: Why is it that many people think Arduino is just for fun, and is anyone actually using Arduino for projects? Or is it merely a toy for learning? Although Arduino may not perform as well as some high-end professional development boards, it has its own unique applications and … Read more
