Voice controlled TV
As seen in the picture there is an Arduino Uno with a protoshield on top with an IR receiver and IR LED. I undertook this project to learn how we used infra red light to control everyday devices and why it was used so often. I found that the process behind it is actually quite simple and I now have a better understanding of what is happening in the invisible infra red world.
The basis of the code was taken from adafruit as this is where I mainly learnt how it all worked.
