Jeremy, I am liking …
Jeremy, I am liking your Arduino tutorials very much, but I must correct you on one point…
The “W” in the digitally controlled variable resistor stands for “WIPER” not washer. Think windshield? wiper; that is the physical design of the moving part on the analog pot variable resistor.
Otherwise, keep up the good work.

Great video- as always!
Keep good? stuff coming:)
thank? you

really helps a lot? with my project….
Hi! Thank? you for …
Hi! Thank? you for spending your time for these awesome tutorials!
I see that the three leds have different time in growing and fading light, but in the code are the same numbers of levels… it’s my wrong impression? Led 0 is faster than others :))
Anyway good work!
is that a robot arm …
is that a robot arm that I see on the rightside of your table? do you use your arduino? to control that arm?
@hebrewhammer1000 …
@hebrewhammer1000 IE, if the clock frequency? is fast enough.
@sciguy14 what …
@sciguy14 what exactly do you mean by “If the SCLK of the? SPI bus is sufficiently high”
@sciguy14 thank …
@sciguy14 thank you for the reply. i am new to using spi but my understanding is you have to use the chip select to? chose what chip i want to sample from? so you would have to cycle between the 4 MCP3208 which would mean i wouldn’t be able to continuously sample all 4 MCP3208. is my understanding of spi incorrect?
@hebrewhammer1000 …
@hebrewhammer1000 Why can’t you now? Is it a hardware limitation? If the SCLK? of the SPI bus is sufficiently high, I’d think you can do all the buffering internal to the microcontroller.
Really great video …
Really great video thank you!!! I had a question that I hope you could answer.
I am trying to build a usb based data acquisition system that has 32 channel with a minimum resolution of 12 bits and has a sample rate of 100-200hz. I decided to use 4 of the MCP3208 which is a 8-Channel 12-Bit A/D Converters with SPI. The problem is I would not? be able to continuously sample all 32 channels. Do you know of a way to buffer the SPI output of the MCP3208 or another way to sample all 32 channels?
amazing work !!! I …
amazing work !!! I was having some hard time understanding some aspects of SPI, all of them got solved by watching this video. Really really big thanks for such a proffesional quality videos, hope you continue with them for long. Its really easy learning arduino with your videos.
Proposals for future videos:
– graphics LCD
– GPS module
– GSM module to send sms, receive sms and answer? back or do something, upload data via GPRS
– USB data storage
once again, thanks!!
hey Jeremy i can’t? …
hey Jeremy i can’t? see the episode 9 on your channel.
hello what? is the …
hello what? is the diferance between netduino and arduino
you? cold have used …
you? cold have used one lower value resistor common to all ground.
why you are so good …
why you are so good. I am jealous . How old? are you. What is your education , and what your projects till now. We like to see them in a video
Awesome? work …
Awesome? work Jeremy keep up the good work, love all ur videos, good to see someone taking the time to teach this.
very nice series, i …
very nice series, i am learning from these videos alot. Thankyou! Jeremy.?

@thekiller0673 your? welcome!
you say” thanks for …
you say” thanks for watching” i say”thanks for taking the time to plan out this video and posting it for free”, i love this videos and the things you? do on youtube.
@raghunitin Maybe …
@raghunitin Maybe not complicated to? me or you, but these tutorials are aimed at people who are just getting started with electronics.
