I'm working on a project currently, though things aren't quite working so I would like whoever's advice.

So, to put it briefly, I'm using a Sparkfun Flex Sensor and an MCP3008 hooked up via a Raspberry Pi. However, the MCP3008 is not picking up on the sensor's output. Well, that's what I think is happening at least. Anyways, I cannot seem to be able to figure out how to do this properly, and I'm not sure if this is a problem with the code or the wiring. In case you were wondering, I followed Adafruit's tutorial and I am using their example code.

I've been experimenting with this for a day or two now. Sometimes, all channels seem to be getting a value of 1023, and other times it's just at 0.

As of now I can't take a picture of it, but I'll make sure to upload one when I can.

i couldn't comment as of now so answering anyway if copied the code right it should work fine

Note: Copy the code from GitHub not from the blog because in blog they present only snippets of code so check that out once again if it didn't work comment below

  • I did take the code from Github. It hasn't been working. – Procinogen Feb 3 '18 at 1:34
  • hope this video help you out linkif not your MCP is faulty – Sampath Madala Feb 3 '18 at 12:25
  • I tried that video you sent. It hasn't worked, for me at least. I'm trying to set up a voltage divider with the flex sensor. My MCP probably isn't faulty, I tested both of the MCPs I ordered and got the same output. – Procinogen Feb 4 '18 at 17:52
  • Pin 19 (MOSI ) -> pin 11 (Din) Pin 21 (MISO ) -> pin 12 (Dout) Pin 23 (SCKL) -> pin 13 (CLK) Pin 24 (CD0 ) -> pin 10 (CS) Pin 6 (GND) -> pin 14 (AGND) & 9 (DGND) – Sampath Madala Feb 5 '18 at 7:42
  • try checking if any VCC pin is connected to your channel pin in that case you get full value 1023 – Sampath Madala Feb 5 '18 at 7:57
