My First version of curtain control Node is ready, installed and tested. Some work is pending, which I'll complete on my weekend.
Edit: Code for the Node:Curtain Node
Curtain Control Node.

Please share your feedback so that I can improvise.

@mfalkvidd Thanks for your suggestion. It works great.

Can I use i2c EEPROM for OTA bootloading with DualOptiboot or it has to be Serial SPI. I was not able to find any documentation on it. I brought a breakout board and it seems to be i2c, and i2c chips are easily available where I live.

Its a Geared DC Motor with Voltage Rating of 6-12V and 100 RPM. I am using a L239 to control the motor.

Thanks @mfalkvidd and @gohan . That helped.

@ahmedadelhosni Hey, I found this article. Seems like the guy has used i2c for remote flash. I was not able to extactly understand whats going on, maybe you can help.
