My elderly grandmother has dementia( Alzheimer's ) and is unable to operate her television properly. I developed this universal remote so family members of the elderly can View, in combination with a remote viewing program (Teamviewer) and a webcam, and control a television from home..
This also saves the codes to the EEProm, so if there is a power outage the codes are saved.
We are using it to switch the television between the cable and a laptop (so she can watch videos online).
Use..
Build the 2 circuits.
Upload the Sketch to the arduino
Use the serial monitor to see the menu.
press 1 on the menu to configure each button.
Make sure the LED is pointed at the front of the television.
