with this device we can control some electric consumers
with standard tv remote control. the circuit is made of
PIC microcontroller which decodes signal from infrared
remote control. the signal is sensed with three pin TSOP1738
ir sensor which demodulates signal so on the data pin we have
a pure digital signal, coded of course. Analyzing the coding
of this remote with logic analyzer shows that the remote
is sending 32 bits and the coding is made by varying pulse width.
So to decode the signal I decide to measure the width of each bit
with microcontroller to determine is it "0" or "1".
