I have a request PLZ make a video that demonstrates communication from an ARDUINO R. F. I. D. card reader when I need to read the tag of an R. F. I. D. card ONLY! hence the commercial type you find in the market allows you to read and write which I do not need the write function ever.

sorry for the late comment, in 3: 20 you mentioned that you need for each device a pin. well shouldn't a shift register do the job? of corse you'll have then to program an interface for that, but then instead of using n pin for n device you'll use only 3 pins for n device!

You have made the things I did not understand much clearer and I now do understand more than I ever have before. You are GREAT! Thank you so much. I am looking forward to seeing more of your hard work. Also, I will be ordering some PCB's from your link.

Hello Sir, this video is great and so is that I2C communication! I was wondering if you could make a video on UDP communication which according to my research is one of the fastest wireless communication protocols. It would be very helpful.
Thanks.

hey you should lookup bitfields. like when you declare members of structs as being a few bits long! i bet the version of C arduino uses does that, and it'd probably save lots of messy yukky binary arithmatic if you could just pack a structure: D

at 6: 15 I think that youve incorrectly identified CPOL = 0 and CPHA = 0 as Mode 0. This should be Mode 1.
This is verified at 4: 28 where the ds states that only Modes 1 & 3 are supported.

Guys. am looking for a trusted website where they solder electronics circuits for regular customers cause I got an Intel chip(BGA) and am having a hard time assembling.

Thank u Great Scott for another great instructional. Great idea to test the SPI module first by making it output a square wave. Thanks!
