Weekly Progress
I made PCB of transmitter remote and design receiver circuit. But I can’t did it done,
I have a lot of problem in programming and the transmitter system. It’s can’t decode a signal
completely and still sent a signal too closer. I tried to debug this code so long but not finished
becuase I have no time do it all day. IC TSOP4838 can’t detect signal when transmitter is far from
receiver circiut.

Engineering Analysis
Strong Point
PCB area is small and reduce power down.
Week Point
I my programming skill not perfect enough for receiver circuit and knowledge about remote it’s too
few. I must spend the time to study concept of remote before I do it.
Next Week Job
Everything about remote must be complete.
