About This Episode:
Time to dig into the guts of the project! 💥 In this video, we break down the hardware behind the Smart Garage Door system and show how everything connects.
We kick things off with a high-level circuit diagram featuring the ESP32 and four key sub-circuits:
🔹 Garage Door Sensor – tracks door position
🔹 Garage Door Button – mimics your wall-mounted opener
🔹 Device Status – provides visual feedback using a "blink code"
🔹 Device Control Button – allows manual toggling of the device into various modes
Then we zoom in 🔍 and walk through detailed schematics for each sub-circuit — showing exactly how they hook up to the ESP32 pins.
To bring it all home, I share real photos and video of the development board so you can see how the schematics translate into actual hardware on the bench 🛠️📸.
Whether you’re following along or designing your own spin on the project, this episode helps you build with confidence. Let’s wire it up! ⚡️
