Hello all,
Could someone please help me with the below? I am essentially making a device that can raise/ lower my rf projector screen from the 12v trigger port on my projector. The idea is coming from this GitHub. https://github.com/ndoty/rf-projector-screen
There are 3 pieces of hardware, green board= rf transmitter, small blue board= 12v to 3v convertor, and Arduino nano.
Below are pictures of what I have done so far. Essentially I don't know if I have it wired up properly and was hoping someone could review it for me. Also, the big thing I'm scared about if the "common ground". Have I wired the grounds properly? If I understand what I am doing, I have 2 power feeds going into this system, 1 from the 12v trigger port and one from the 5v power plug. Am I supposed to have a wire going out of the ground pin of the 12v to 3v convertor to the ground on the nano? Are there issues with my wiring/ grounds in general?
Attached are photos. Thank you all again for any guidance you can provide!!
