In this animated object, students view diagrams of the UJT as it is used in the relaxation oscillator circuit. Waveforms illustrate how the circuit operates through several time periods.

Learners view animations showing how a time-of-flight flowmeter uses ultrasonic sound waves to measure the flow of a liquid.

Learners examine an animated motion-controlled robotic arm and observe the operation of a PID (Proportional-Integral-Derivative) control that makes movements quickly without overshooting or having a steady-state error. This activity has audio content.

The learner will learn the programming steps that are used to create circular motions with robots.
