curious, see your values seem to be 0-1023... my ADC MCP3008 is giving me 0-65535... but then I'm using chan.value and chan.voltage as chan = AnalogIn(mcp, MCP.P0) is it supported to run the MCP Vcc and vRef on 3.3v from the Rpi. run the 5V of the Rpi to a sensor that has 5V input, and 0-3.3V output back onto the MCP analog in's ? G
I’m using your code in thonny on my pi and it doesn’t seem to work it keeps saying that it cannot find the Adafruit GPIO and I know I installed it do you have any idea what I’m doing wrong
Great video - would I be able to plug a Resistance Level Sender into this? The type with the float which changes the resistance as the float moves up and down it?
Hello sir. I have a problem with MCP3008 sampling frequency. I am trying to increase clock speed for better sampling rate but it does not work. Is there any way for this or any suggestion? And also I tried software SPI configuration, it gives an error does not work either. Thanks for your explanation.
I typed this in my search, couldn’t find this video, then wait two days and it’s on my recommended, if anyone else is wondering what’s going on with google ad and search engine ai let me know cause this is nuts…. Anyways, thanks so much for this video!
I was told that the MCP3008 is capable of a much higher analog sampling frequency compared to the Arduino 9.6khz (= 16 MHz/[13 clock cycle for a conversion * 2^(7bits)]) . Do you know if that's true?
Hey John, According to the datasheet at (ww1.microchip.com/downloads/en/devicedoc/21295c.pdf) the MCP3008 running at 5.5v is capable of 200k samples per second. At the lowest voltage it can run at (2.7v) it does 75k samples per second. So yeah, A bit higher!
This is well thought out and informative video. Thank you for making it ! I subscribed to your channel.
Amazing ! this really saved my project ! useful and well done stuff !

chan = AnalogIn(mcp, MCP.P0)
is it supported to run the MCP Vcc and vRef on 3.3v from the Rpi.
run the 5V of the Rpi to a sensor that has 5V input, and 0-3.3V output back onto the MCP analog in's ?

MCP3008 사용에 대한 거부감을 줄이는데 큰 도움이 되었습니다.
This video is more less stress My using MCP3008 module.
good video!
you made my day
Thanks a lot! 感谢！思路，讲解清晰，听明白了。

Great video, Can we use K type thermocouple as the analog input instead of potentiometer? I have to interface thermocouple and raspberry pi?
Is there a chance you can repeat the raspberry part using Windows IoT Core in C#?
Sir, are you sure pin 22 is SPI CEO?
For hardware SPI, 24 and 26 are the CEO pins
he has it connected to 24 anyways right? (edit: yeah just saw the update)
How come no ( ) on the print commands?
Python 2. Have since switched to python 3 for future projects, my mistake for not switching sooner!
@@makersdigest4752 Ah I see. I'm trying to read voltages on my pi, but as a human bottleneck it's not going well.
I see that you don't use level shifter from 5v to 3.3v and back to the MCP3008?

Hi can you do an part 2 with the raspberry pi and mcp3008 and interface it with cayenne for iot interface the output of the AC/DC readout
You can use the K9V1 - then You have the names of the PINS - I use 2 because of the fan
not working. double checked. all ... fixed for python3 .. nothing. thanks anyway.
Notice the update in the video description. In the video it says pin 22 but it should be pin 24 for CE0.
