Minimalist remote controller for smart TV (or something else).
Remote controller with reduced instruction set. Massive 12 mm tactile switches in color. Arduino Mini. Optional small OLED display. Recycled mobile phone battery for power, USB charged.
Firmware : Less than 8k code size. Switch activation interrupt wakes processor from sleep, scans 16 switches for commands, OLED display shows command, IR diode drive. Repeat and power save.
In sleep state the 4-5-6-7 outputs are held low. Input 2 has the pull-up activated. Pushing a switch pulls 2 low via 4148 diode and activates interrupt. Processor wakes up, turns display on and scans keyboard. Fetches IR remote code from a table and drives IR LED. Scans keyboard again for code repetition. After timeout, turns off OLED and goes to sleep.
Copy your controller : choose keys to operate your smart TV. I found that 12 keys are enough for everyday use. Run the following to find out more about your remote : https://github.com/Arduin
