Hey people,
Thank you for your replies.
I will do this for a project of my microchips lecture.And to learn how rf modules work.
I have a basic 433mhz rf module already.But i don’t know its model. My rf module doesnt have its preamble codes.So I have to write these codes.
And yes I have HT12E/D for my circuit.The photo I sent was only for showing what I am trying to do.In addition to this photo i have rf module and HT12 E/D in my circuit.I didnt try it yet because I dont have a 8051 programmer.On monday i will try it at the school.
