Hello,
(let me know if it's not the correct category)
I'd like to connect my projector screen to Google home or OpenHab, to make it go down, up and stop.
One end would be connected in MQTT and the other end (to the screen) via rs232.
It has a RS232 connectivity via a RJ45 physical port, and I was able to obtain this info from the company:
Going Up : FF EE EE EE DD
Stop : FF EE EE EE CC
Going Down : FF EE EE EE EE
Bit/sec : 2400
Data bit : 8
Data Parity : none
stop bit : 1
Flow control : none
I've no knowledge about Arduino, I guess I'll need a wifi and rs232 module.
Would the Uno rev3 be a good start ?
Any recommendations of what to buy/avoid, good sample project to start from ?
Thanks,
CrazyToaster
