This is an infrared transmitters signal circuit that is small size and using a power supply 1.5V only. by main electronic part are two the LM3909 (a LED Flasher Oscillator IC) Normally, we tend to put it to use as a simple flashing light circuit. Using a 1.5V low power supply, it’s working now, Easier [...]
This encoder can generate up to 19,683 codes from 9 address lines by detecting 1,0, or open circuit. To initiate the transmit sequence, pin 14 should be pulsed low. The encoder will now output on pin 15 a data stream representing the condition on each of the address/data pins in turn and then repeat the [...]
This 1 channel infrared transmitter/receiver remote control is the cheapest and simplest you can find. The transmitter transmits a sequence of pulses on 36 KHz frequency carrier. The diodes are Schottky type because of their low voltage drop (only 0.2V).
