low's honest review, The ESP32 IoT Device I’m Building to Collect Sensor Data — For Beginners and Arduino Users course

I looked into YouTube and books to try and make a custom board, but I felt lost because there wasn't as much information as I expected. The most helpful part of the course was the hands-on process of drawing the schematics and performing PCB routing myself using KiCad. Also, in Section 5, using the board I made along with the firmware source code allowed me to clearly grasp how data moves back and forth via BLE and Wi-Fi. Thank you so much.
