How do HT12E Encoder and HT12D work ?

[@charlesspringer4709]

Awesome AI read of a data sheet

[@jozefnovak7750]

Super! Thank you very much!

[@PHYTION1]

Thank you too!

[@olivierconet7995]

Interesting, thanks.
We all done this mistake 😁: GND wire missing in the demo (those circuits use a CMOS logic level, not RF)

[@davepompea]

I believe it is there. It's a bare wire so it's hard to see.

[@srenkoch6127]

@@davepompea
Alternatively, if the transmit frequency is high enough, the capacitance of the transmit and receiver boards may be high enough to act as ground through the table :-).

[@tookitogo]

⁠@@davepompeaThere is no bare wire between the two breadboards. Just the yellow insulated signal wire.

[@shaunclarke94]

I was curious about this also. I'm guessing it works as it's designed for RF?

[@davepompea]

@@tookitogo Oh, right. I wasn't thinking about *that* wire. D'uh!

[@fareswissam8205]

The lesson explanation is very wonderful

[@PHYTION1]

Thank you! 😃

[@geooogle]

Thanks do more please. I can read just fine but you're awesome when I don't want to read

[@PHYTION1]

sure, It's my pleasure

[@anandazhagappan964]

Great video!
How do you determine the resistor value sir?

[@santhanamsan316]

what software you where using

[@Garrysome00]

My HT12D and E board from amazon output pins are constanty on when button pressed on transmitter output pin is off. I dont how to fix it.

[@boonedockjourneyman7979]

Thank you.

[@PHYTION1]

Welcome!

[@LarsPW]

In your experiment you provided both sides of the transmissiom with electricity from different batteries, but I did not see the common ground conection. To get over longer distances it is better to have a differential transmission giving the same signal positive and negative (symmetrically).

[@PHYTION1]

yes. It is a mistake I have made.

[@boblewis5558]

In which case you'd need, 433MHz tx & rx or use a bus specifically for differential drive like RS485 or even use CANbus

[@LarsPW]

@@boblewis5558 ... in any case you need to spare wiring without wanting to employ wireless transmissions, e.g. in a machinery transmitting controlling signals onto moving parts.

[@boblewis5558]

​@@LarsPWTrue! But then you lose a huge element of physical security for the low extra cost of some cable.
I avoid wireless connections, including WiFi, as much as possible as they are SO easy to hack, even for rank amateurs! 😢

[@LarsPW]

@@boblewis5558 I share your opinion on wireless connections within machinery. But sometimes trunks of wires are not applicable for mechanical reasons and/or to avoid crosstalk problems. Therefor are these and some other chipsets made. Years ago I heard about cascadable ICs to make 8-, 16-, 24- or 32-bit wide serial transmissions possible.
But I think that the HT12x are rather intended for wireless transmissions, otherwise they would have integrated differential outputs.

[@Rohan4IN]

Will it work if I use two sets of encoder and decoder with different address for each pair and send the data through one wire?

[@PHYTION1]

Yes it will

[@0x9D99]

More of this pls. And the actuator.

[@PHYTION1]

sure

[@anandazhagappan964]

HT 12E encodes 4 bit data value.Is there any CMOS IC for 2 bit data?

[@marekpospa1266]

Jak to, že ti to běhá po jednom drátě?
Proč není propojeno GND?

[@PHYTION1]

zde nepotřebujeme další drát pro GND. Můžeme přenášet data pomocí jednoho drátu. to je specialita tohoto ic

[@tookitogo]

@@PHYTION1No, that is incorrect. The data out and in, respectively, are CMOS logic outputs/inputs. They still need a ground reference.

[@jimknopf705]

Thanks.

[@PHYTION1]

You're welcome

[@billbobby461]

3:53 your faith is misplaced sir

[@PHYTION1]

you're correct
