“You are armed with a lightweight and time-saving universal remote control system.
Story
If the projector does not respond to remote control commands, try the following solutions:
Check that the remote control batteries are installed correctly and have power. If necessary, replace the batteries.
Make sure you are operating the remote control within the reception angle and range of the projector.
Check to see if a button on the remote control is stuck down, causing it to enter sleep mode. Release the button to wake the remote control up.
Strong fluorescent lighting, direct sunlight, or infrared device signals may be interfering with the projector’s remote receivers. Dim the lights or move the projector away from the sun or interfering equipment.
If available, turn off one of the remote receivers in the projector’s menu system, or check if all the remote receivers were turned off.
If you assigned an ID number to the remote control to operate multiple projectors, you may need to check or change the ID setting (feature not available with all projectors).
If you lose the remote control, you can order another one from Epson.
We need to repeat the same process over and over again if we want to go through it.
What if we have a device through which we can control a projector without worrying about the problems like that of a battery’s power?
In order to achieve this solution we we used WIZnet’s S2E, along with Arduino UNO controlled by a mobile app and finally we could control all the functionalities of a projector.”
