Thanks. After trying it on an esp8622 without success I could only get it to work using this video!
it just does nothing than stucking in the loop after "Place card" in test :/ tried all different libs already but none works, my RC522 board looks like yours but it wont read/write anything :(
using n in lcd.putstr(" scan rfid") function it gives next line. In driver putchar == 'n' gives newline, but i wonder how you got the Output. Nice Tutorial!!!
Amazing video!!! Thank you so much!!
Nice project. Very Very interesting. Thanks for sharing
It's my pleasure brother. Thank you.
Thanks you!
as usual,great video very informative.
Glad it helps. Thank you.
Hi, can u help me plz, I have a variable uint32_t chipId; i want to write its content to an rfid block(for example 60) how can i do that?
First of all, thank you for all your videos, I just know how to program in Python and these ones are really helpful to get into applied electronics. I just wanted to ask if there is a way of modify/write the information of the cards? I've been looking through the libraries but none of them let me modify the info when tried eventhough there are some that have a "writing function". Thank you!
Hi Miguel, thank you for the appreciation.
With regards to your concern, you may go to the github source and under the folder there are 2 files 1 for reading the mfrc522 and another for writing to it github.com/cefn/micropython-mfrc522
I haven't fully tried it but it's working with me as far as I can remember. Cheers, George.
@@TechToTinker Thank you so much for the quick reply, I will try because I couldn't even with this so sure I'm doing something wrong. Thanks!
Should the LEDs have current-limiting resistors?
Hi @I'm not Chuck, yes you can add a current limiting resistor. I just added the led indicator when I am about to record the video, my bad :). Thanks for correcting. Cheers.
@@TechToTinker I watched the entire video, and learned about RFID, although I don't have a use for it. In fact, I have watched all of your ESP32/Micropython videos, and learned quite a lot.
@@ImnotChuck. wow, that's great. Really appreciated and thank you for the support.
@@TechToTinker The current is limited by ESP32. Each port is limited at 25mA. It 's ok for the led.
hi! thanks for your videos on ESP32 in python. Are there plans to show how MQ series gas sensors work with ESP32 with Python?
Hi @Background Music, yes there will be. I just need to finish some more other modules then the MQ gas sensors. Thanks.
@@TechToTinker Many thanks
@@backgroundmusic3152 it's my pleasure. Cheers.
