Arduino using accelerometers and flex sensors, help !

Other Hardware Sensors

Hello all,

I'm working on a project, making a glove that will influence my music on the way i am moving my hand.
So i started with a 3-axis accelerometer and 5 flex sensors, but now i only see tutorials where they use the analog pins for both the flex sensors and the accelerometer (so i need 8 of them) but my arduino uno board only has 6 analog pins. i tried to put them on the digital pins but the values changed in range or even didn't change at all if movement occurred. as i am not that experienced i also don't know if this has something to do with the digital pin code or that i have to add some things in my code or in the circuit or whatever. so my question.

Will it make a big difference or is it even possible to use the digital pins for accelerometers or flex sensors ?

Thanks in advance !

Most modern accelerometer modules have I2C or SPI interfaces, and are hence digital.

I2C uses A4 and A5 by default as digital pins on the UNO, but you can use software I2C on any other pins.
