@@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 :-).
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).
@@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.
@@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! 😢
@@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.
Awesome AI read of a data sheet
Interesting, thanks.
We all done this mistake 😁: GND wire missing in the demo (those circuits use a CMOS logic level, not RF)
I believe it is there. It's a bare wire so it's hard to see.

@@davepompeaThere is no bare wire between the two breadboards. Just the yellow insulated signal wire.
I was curious about this also. I'm guessing it works as it's designed for RF?
@@tookitogo Oh, right. I wasn't thinking about *that* wire. D'uh!
The lesson explanation is very wonderful
Thank you! 😃
Super! Thank you very much!
Thank you too!
Thanks do more please. I can read just fine but you're awesome when I don't want to read
sure, It's my pleasure
Thank you.
Welcome!
More of this pls. And the actuator.
sure
Great video!
How do you determine the resistor value sir?

yes. It is a mistake I have made.
In which case you'd need, 433MHz tx & rx or use a bus specifically for differential drive like RS485 or even use CANbus

You're welcome
HT 12E encodes 4 bit data value.Is there any CMOS IC for 2 bit data?
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?
Yes it will
what software you where using
Jak to, že ti to běhá po jednom drátě?
Proč není propojeno GND?
zde nepotřebujeme další drát pro GND. Můžeme přenášet data pomocí jednoho drátu. to je specialita tohoto ic
@@PHYTION1No, that is incorrect. The data out and in, respectively, are CMOS logic outputs/inputs. They still need a ground reference.
3:53 your faith is misplaced sir
you're correct
