This might seem silly to many of you, but I lost my TV remote when I moved awhile back and instead of buying a universal remote for cheap, I want to make a remote for my TV from scratch myself. I'm talking about designing the pcb, soldering parts together, the whole shebang. I know nothing about electronics and thought it would be a great way to learn.
I just need some guidance on how to start or advice on whether this is even possible without having the original remote to decode the IR signals? Am I able to look up the IR codes for the receiver by looking up the model number of the TV? What components do I need and how do I organize them on the circuit board?
I know basic parts that I would need are an IR LED, transistors, push buttons, and a microcontroller. I'm not sure which specific transistors or microcontroller to use though or how to design the parts on the pcb. Pointing me in the direction of useful resources would definitely help. I've already read a few instructables and watched a few videos on making a remote, but none of them told me how to design one from scratch for a specific receiver without the original remote. Thanks in advance!
