This one is interesting just like displaying a custom message on LED matrix banner. Just from an Android phone on our finger tips. Change at anytime anyhow, at just one touch.
The whole simulation video is available at youtube link below:
You can download hex file and proteus simulation at end of the post.
This device can be used to control your home’s all 230V appliances directly from your PC. We can do it via the serial port of our PC. We have used the 8051 microcontroller here. We are communicating via the RS-232 port.
The circuit is designed in the proteus ISIS software. I have first simulated the circuit in the proteus so that all correction and debugging process is done in the PC itself. So we don’t need Continue reading
