The video above explains the basic theory that relates to data transmission, namely how electromagnetic waves are generated by antennas and how they encode 1's and 0's. Non essential information for a hobbyist, but really interesting none the less.
Component list:
•1 X Arduino Uno
•1 X 433MHz RF link pair
•3 X LED
•1 X Piezo Buzzer
•1 X Push Button
•1 X Resistor 330Ω
•50cm Single Core Wire
Equipment needed:
Soldering Iron

After 8 years from this video you must be some advanced engineer now.
-
Nice and informative. Thanks for taking the time to make these videos.
-
I like to know is there a portable thin receiver to pickup phone carriers LTE radio bands like 2-4 and powered by using a elbow type C connection to the phone.
Seeing Xiaomi mi Pocophone F1 Global OTA Unlocked snapdragon 845 CPU phones do not have the LTE radio band of 2-4 ❤️ -
Thought you probably should've went into carrier waves since you're gonna talk about how these waves transmit signal of information. Good high level lecture.
-
Very well explained, thank you
-
Does music that is already downloaded to your phone use data Transmissions or data transfer
-
Sir, you are AMAZING! I appreciate this tutorial so much!
-
Thank you very much. You brought it all together very well.
-
what is the "black box" called in the world of RF Circuit if I want to learn more about it??
and thank you for the great video -
Amazing explanation.
-
How hard is-it to build RF devices (transmitters/receivers) from scratch using basic electronics components ?
Thanks for the info btw -
I wish you didn't say 0s and 1s.
You did good with calling it electromagnetic waves, amplitude or frequency modulation. Suddenly you went from that to mathematical symbol which is algebra.
Amplitude refers to voltage and frequency refers to energy delivered. -
do you think it's possible to change a device that uses wifi to transmit data (like a portable car diagnostic scantool that connects to a cell phone app to read information via wifi), to a bluetooth connection? ie. swapping out wifi and replacing it with bluetooth internals from say a portable speaker?
-
Great explanation!
-
Awesome Thanks!
-
bro! how to generate code from Arduino (or Wemos 8266) + Transmitter for Remote learing code ( It doesn't have code)? thansk a bunch!
-
remember, human beings are also recievers - and we are effected by EM frequencies.
-
If radio waves are everywhere, how do you know which radio wave to receive and interpret?

Really good! Thank you.
