Hello,
I need some guidance to build a project. I want to build a keyboard which connect to relay then the relay will connect to rectenna. Here is my idea, when I press keyboard key (in example: scroll lock or combination from alt+h) it will trigger relay to active, and if I press it back it will be inactive. The function of relay connected to rectenna is, if the relay off the rectenna will consider as on and vice versa.
I wanted to follow a step from this project, but do not know how to use it if only with one relay. I already buy a 5V SPDT Relay and usb keyboard, antenna will be built, and still wonder how to connect both of them.
I only understand how to built antenna by now, so I would be grateful if anyone will help me to build the project.
Thank you.
