FSR 400 Force Sensing Resistors To The EZB4?

Now I have another question for you Jeremie.

I need to know if you can tell me how I can attach there FSR 400 Force Sensing Resistors to the EZB4 for finger touch sensors?

The FSR 400 short-tail model is a single-zone Force Sensing Resistor optimized to use human touch to control devices for use in automotive electronics, medical systems, and industrial and robotics applications. FSRs are two-wire devices. They are robust polymer thick film (PTF) sensors that exhibit a decrease in resistance with increase in force applied to the surface of the sensor. This device has a 5.6 mm diameter active area and is available in 4 connection options.

Hey @smiller29

I would recommend using a Voltage divider configuration and attaching them to the EZ-Bv4 ADC ports.

VCC would be 3.3V from the ADC power rails, 0V would be GND from the ADC power rails, and Output Vo would go to the ADC pin.

So you have two connections on the FSR 400 connected to +VCC 3.3V and and the second connection goes to Vo with a Vo also connected through a 10k resistor to ground 0V

@smiller29 That's correct! You can mess around with different values for the 10k resistor to get more precision but 10k is a good value to start with.
