Circuit diagram of IR TV remote control using 8051 microcontroller also explain its working?

∙ 11y ago
the 8051 is a micro controller
the buttons tell the 8051 to do something
there is an ir led on an output bit of the 8051 that shines on the tv ir detector
it pulses a code the tv knows
or window fan, ac , vcr, dvd
the other output bits are used to scan multiple buttons
like the difference between a rotary and touch tone Phone
ive seen them with tms1000 and z8
thermostats may have 68hc11 it has 8 channel a/d right on it
circuit diagram is very trivial its all in how you pulse the led
