 WEEK 2 I currently have a small project that I'm very passionate about and have been working on: an embodied intelligence/edge AI project. It's similar to a companion-type desktop robot. My main goal with this project is to build and manage a complete system encompassing perception, cognition, decision-making, and execution. Below are the hardware circuits I've already built, along with some of my structural plans. This is the current hardware circuit design, and it's unlikely to undergo significant modifications in the future. The speaker, servo motors (which are inductive loads), and multiple power-consuming sensors may generate various frequencies of noise, as well as voltage drops or instability issues when operating simultaneously (especially the servo motors; I didn't use a driver board due to size constraints). Therefore, the circuit primarily utilizes filtering circuits composed of small-capacity ceramic and electrolytic capacitors (multi-stage decoupling),...

 WEEK 1 WEEK2 2.4GHz!!!for esp32S3 When connecting to Wi-Fi, the ESP32 development board does not support 5G networks; it must use a 2.4G network, which is the IoT network. I only obtained the SSID and password after logging into my home router's administration panel. I noticed that my home Wi-Fi's 2.4GHz and 5GHz networks use completely different account names and passwords. My Linux system is connected to the 5GHz network, while the MCU is connected to the 2.4GHz network. They can communicate normally, which surprised me, because I wasn't sure if this would work, as the 2.4GHz and 5GHz networks seem to be distinct. WIFI of respberry-Pi: I couldn't find the standard network configuration file on my Raspberry Pi.  I had initially configured it to connect to my home Wi-Fi when I flashed the Ubuntu Linux system onto the SD card using the Raspberry Pi's dedicated flashing software. I took the Pi to school and used it there once, changing my phone's hotspot name and...
