This is not very much related to robotics but i have a doubt on how to read data form a single pressure sensor that has been arranged in the form of a linear array. the sensor is a resistive ink sensor whose resistance decreases linearly with pressure. for an application, the sensors are arranged in a linear array (19 sensors arranged in a single line) and the finger is moved over the array. my aim is to build a circuit that can read this finger movement and display the results in a computer. from the data in the computer, i can see how much pressure i have applied during the whole course of movement of my finger.
This is my purpose and i dont know the circuit and the algorithm of how to scan the sensor data using a microcontroller. i am planing to use serial communication to send the data to the computer where a graph is drawn with the data. moreover the ADC part is only comfusing me. should i use a single ADC or many? are there any circuits like this or should i design one? please guide me.
Thanks in advance!
