infrared signal is used as the "trigger" for the operation of dc motors(or any other appropriate devices eg:LEDs).
i have used the arduino uno as the microcontroller as it simply does the job!also it's cheap too!!
future application will ultimately lead to IR controlled robot,and perhaps controlling of human mind using nothing but a simple remote control and interfacing hardware with electrodes,so that the physically disabled can attain normal "motor" functions.thanks.
Looks like a nice video.
BTW, why did you post it here? This is the forum for asking for help. Better move this to "show your DIY" https://www.edaboard.com/forums/56/
