Learners examine a 555 integrated circuit, which functions as a one-shot monostable multivibrator, and then test their knowledge. Immediate feedback is provided. Animations are used to show the sequential operations.
In this interactive and animated object, learners examine the duty cycle of a squarewave produced by a multivibrator using a 555 IC (integrated circuit). A brief quiz completes the activity.
In this animated object, learners examine the types of information to enter, and the sequence of steps required, to program a programmable logic controller (PLC) timer.
