- In this episode we take a look at the MCP3008 Analog to Digital Converter IC. With this chip we can add Analog inputs to a Raspberry Pi, or extend the analog ports on an Arduino.
UPDATE: CE0 on the Raspberry PI is pin 24 NOT 22. Ill put updated schematics on GitHub & makersdigest.net.
In this video we cover:
► Physical connection of the MCP3008 to a Raspberry Pi
► Code examples for the Raspberry PI in Python
► Physical connection of the MCP3008 to an Arduino UNO
► Code examples for the Arduino
As promised, all the code used in this video is on Github!

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 !
MCP3008 사용에 대한 거부감을 줄이는데 큰 도움이 되었습니다.
This video is more less stress My using MCP3008 module.
good video!
Thanks a lot! 感谢！思路，讲解清晰，听明白了。
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!
you made my day
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?
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#?
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
I see that you don't use level shifter from 5v to 3.3v and back to the MCP3008?
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’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
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)
You can use the K9V1 - then You have the names of the PINS - I use 2 because of the fan
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!
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.
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.
