@Richard R. Are you going to use the finger tip sensora on your inmoov? I'm printing a new hand and would like to make use of the sensors but I don't think ezb support them directly.
Is it very hard to use the i2c from an andrino.
Thanks.
Thank you

Also a good idea is to test it with a multimeter first before testing it on your ezb...
From that picture it looks like the resistor is on both Ground and signal. I not sure as I never used one of those pin boards before.
Also I thought the ADC on EZB is 3 volts, I could be wrong. Would that matter?

Thank you.
I am making thu resolved by you.
Thanks.
This sensor should not be operated without placing a 10k resistor in line on either the hot or ground power feed. If a resistor is not used then the pot will burn a hole in it's self if you press down across small gap at the bottom of the SoftPot with your finger or anything else. When you do this you're bypassing the internal resistance and shorting V+ to GND. By putting a 10K resistor in line like I mentioned above this will keep the fault current very low if you bridge the gap and keep a hole from burning through it. This method will also give you almost 95% of the applied voltage all the way to the end of the rails. I've used both 3.3 and 5 vdc with this sensor. Both voltages worked nicely but I seemed to get better response useing 5v. However that could of been just my application. They are rated to handle 1 Watt max so you don't really have to worry about overloading it with the way we use these.
Now if you find your reading is floating to much and cant get a positive reading when touched then you should also put a resister (10K) between the ground pin and the output pin.
