Another project inspired by being lazy! I made a webserver with an ESP32 which I can access over WiFi using my phone, computer, or even smart TV. The ESP32 works in coordination with a DC motor driver board which adjusts the shades.
To add some complexity, I added a ~5V rechargeable battery and accompanying solar panel. I also added a small microUSB cable that sticks out the side of the blinds. In theory I can use it to charge the battery, or just leave it there to power the device!
This is the conceptualization and build video from my YouTube Channel.
Enter the name of your wifi and open serial monitor to find the ip address of your esp32. I left in PWM components of the code commented out, this can be uncommented and adjusted for speed control. For some reason the code cannot be saved with the full code, paste the ADDITONAL_HTML_CODE in where stated.
