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
Overall Scheme Design Overall Structure Design The wheel-leg robot (LeTian-robot2) utilizes a linkage mechanism (see Figure 1), with the linkage controlled by servos. By controlling the servos on both sides, the overall tilt and lift of the body can be achieved. The feet are directly driven by a 4010 brushless motor without any reduction gear. … Read more
1. Circuit Completion Plan In the previous chapter, we identified the circuit modules required for the smart faucet. Next, we will determine how these circuit modules connect to form a complete “system”. Since our system structure is simple and the components are relatively few, it can be roughly divided into three parts: • Power supply … Read more
STM32: Released by STMicroelectronics on June 11, 2007, it is a 32-bit microcontroller. GD32: Released by GigaDevice in 2013, it closely imitates STM32 in chip development, configuration, and naming. In fact, the GPIO pins are pin-to-pin compatible with STM32, meaning you can use GD32 without altering the PCB. Sometimes, you can run STM32 source code … Read more
In the world of the Internet of Things, a typical network architecture is as follows: first, terminal devices or sensors collect signals or information. For devices that cannot connect to the internet or intranet, the sensors send the detected information to a gateway, which then sends the information to the server. Some devices, like smartphones, … Read more
The Internet of Things (IoT) consists primarily of IoT devices, gateways, and the cloud. 01 IoT Network Architecture From bottom to top, there are the perception layer, network layer, and application layer. ▪ Perception Layer: Identifies objects and collects information; ▪ Network Layer: Primarily responsible for information transmission; ▪ Application Layer: Provides rich IoT-based applications; … Read more
