4 Channel IR Remote Transmitter & Receiver HT12A and HT12D H007

Schematic and PCB layout available here,

Channel Infrared (IR) Remote Module using the famous HT12A and HT12D encoder/decoder chips from Holtek.

Supply - Transmitter : 3 to 5 VDC, 5 V @ 20 mA & Receiver : 5 VDC @ 200 mA
Output: 4 channel Latch or Momentary onboard Jumper for selection
Crystal based oscillator for the reliability of operation
Jumper selectable 8-bit address code
LED output to indicate reception
On/Off slide switch in the transmitter
Power-On LED indicator in the Receiver / Transmitter
Valid transmission indicator
4 LED for Relay On/Off status

This by far is the best example i have seen of a true 4 channel Remote.

[Thetwovolt]

Usually RC drone required RF based Remote, IR has
limitations of low range.

[paullandry]

Anyone know how one could get a hold of the finished units or diy kits?

[justaname]

How do you make the HT12D not latch? i looke at data sheet and its the HT12F that doesent latch... i see you have capacitors in the circuit. why not just get the HT12F?

[ayyazalisajjadali]

sir please give me the idea that when I press the button the led and relay etc well remain one

[armandorojas]

Hello, this circuit would help me to control the reverse and advance of a DC motor

[tushartripathi]

sir i have HT12E ic . can i use that in place of HT12A?? if yes then how?? Bcoz i m not getting HT12A in my city...

[bossrizan]

I complete this circuit.
I use HT-12E for transmitter. but it not working.
ir led is alltime on.
please give any suggestion for me.

How to make Stand by mode, show circuit diagram

[MohitAgnihotri]

Can we use HT12D based receiver but any remote of TV, MP3 Player etc? Will it work? Or it must be HT12A-HT12D pair only?

[FahimulIslamBUET]

Please too many of us is waiting for the circuit diagram. Can you at least give us some links through we can get a idea?

[shopehome]

Sir we can design this without remote only work manual with 4 micro switch

[UNITELTECH]

Were is possible to buy online this circuit ?

[gagaksensei]

Sir, Can the four relays live at the same time?

[afifzuhair]

hello can I get your receiver circuit diagram, I need it asap.

[harishbaisla]

sir mujhe ye khridna hai kha se khredo pls bata do

[er.mohammadadil]

Sir please always link the buying website and price.If arduino then codes too

[bharatsurani]

where is diagram this circuit? can you pl share it? You can mail me or get me your details I'll contact you.
