Analog Sensors

In this video, you will learn how to wire and read variable-resistance sensors by wiring up and programming the PSoC to read a potentiometer.  You will learn about the effects of bit resolution on analog-to-digital conversion and the quantization factor.

To complete this lab activity, make a video that includes the following in one video:

(1) You saying your name

Undergraduate and Graduate Students:
(2) Your LCD screen showing the angle of the potentiometer, in units of degrees

Additional Graduate Deliverables:
(3) Your SCARA manipulator moving the end-effector in a straight line parallel to the X0 axis
(4) Your SCARA manipulator moving the end-effector in a straight line parallel to the Y0 axis

Many sensor properties, including many of the common sensor errors, can be read from a 'sensor response curve'.  In this video, you will be introduced to the sensor response curve, and you will learn how common sensor properties and errors can be read from the sensor response curve.

In this video, you are shown how to use the inverse Jacobian matrix in order to control the end-effector velocities.  We find the equations to do this for the SCARA manipulator that you built previously.  In the next video, we'll program these equations into our PSoC to get the end-effector to move at a constant speed in a straight line.

In this video, we write PSoC code to get our SCARA manipulator to move the end-effector in a straight line at a constant velocity..
