This little 125kHz RFID reader puts out a repeating frame of serial data when a card or fob is moved near the antenna. Here I try to decode that serial data using my oscilloscope.

No final RFID project after loading data into module can Arduino be removed for module use only?
What is the voltage on the TX pin ? Will it work directly with an ESP32 or will I need a level shifter ?
Underrated meerkat noise
Can we hook this up to a pi?
how do uincrease the distance to like rly long distances explain i am new i just want to build one
Jonathan I need your help please, please. I've got a 16 way mux connected to a MEGA 2560, the mux lines are for receiving serial input of tag info from multiple RDM6300 modules. I've connected a single module, powered from the MEGA 5v/GND and it reads perfectly from any of the 16 mux lines. However, when I connect a second module, the first one stops working as soon as the 5v/GND are connected. Neither module works. If I disconnect the GND from either module the other one starts working. I've tried using a power bank with the RDM6300s , common ground on power bank and MEGA but same result. I'm freaking out.
I have the same reader. As soon as you approach it with a card, the LED gets slightly darker for a short time. This is visible it dark rooms, yet it is very hard. You can put the LED between the LED pin and Vcc. Then you see a small flash when you approach it
what about edit program in that C8051F330 MCU to not only read cards and tags but also write, or reading/writing automotive chips in keys 😉
Good timing Julian…how do we copy these cards and duplicate it? On tags…
Good video. Can I suggest you get a logic analyser – When you are only interested in 1 & 0 s it's much easier than using a scope. A good USB 8 channel analyser will cost less than £10 and the software is free.
Promoting the MARK OF THE BEAST? READ THE WARNING BELOW, ESPECIALLY READ CHAPTER 13 VERSES 16 AND 17
Revelation 13:
11 And I beheld another beast coming up out of the earth; and he had two horns like a lamb, and he spake as a dragon.
12 And he exerciseth all the power of the first beast before him, and causeth the earth and them which dwell therein to worship the first beast, whose deadly wound was healed.
13 And he doeth great wonders, so that he maketh fire come down from heaven on the earth in the sight of men,
14 And deceiveth them that dwell on the earth by the means of those miracles which he had power to do in the sight of the beast; saying to them that dwell on the earth, that they should make an image to the beast, which had the wound by a sword, and did live.
15 And he had power to give life unto the image of the beast, that the image of the beast should both speak, and cause that as many as would not worship the image of the beast should be killed.
16 And he causeth all, both small and great, rich and poor, free and bond, to receive a mark IN their right hand, or IN their foreheads:
17 And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name.
18 Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six.
HERE IS WHAT HAPPENS TO THOSE WHO WORSHIP THE ANTI-CHRIST OF ROME AND TAKE HIS MARK:
Revelation 14:
9 And the third angel followed them, saying with a loud voice, If any man worship the beast and his image, and receive his mark IN his forehead, or IN his hand,
10 The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb:
11 And the smoke of their torment ascendeth up for ever and ever: and they have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name.
Revelation 19:
19 And I saw the beast, and the kings of the earth, and their armies, gathered together to make war against him that sat on the horse, and against his army.
20 And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone.
21 And the remnant were slain with the sword of him that sat upon the horse, which sword proceeded out of his mouth: and all the fowls were filled with their flesh.
THINK ABOUT IT…DON'T BE FOOLISH.
No Christmas builds?
Is there any possibility to increase the distance of this module or a similar one (passive RFID) to 1 meter?
ok 18 relay board hmmm
That relay board is a beauty. Use it for your arduino driven synchonized to music broadcast on an FM station Christmas light show.
that 31 is wobbling in the most peculiar way. it's messing with my mind
It's a cool thing to tinker with but you do realise ikea tradfri kits are £13 on sale right now, yeah? A switch and a bulb… 🙂
