Infrared transmitters by LM3909

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 to use transistors. The high frequency, it is very simple, just change the device to high frequency only. C1 and R1 is lower the higher frequency.

Remote control Encoder M145026

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 operation, so that two complete identical words are transmitted. If pin 14 is held low, the output will be continuous, otherwise two identical words are output for each pulse on pin 14. A 1 is transmitted as two long pulses, a 0 as two short pulses, and an open circuit as a long pulse followed by a short pulse.

Simple Infra-Red Transmiter – reciever Shematics by IC4060

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).
