Part 1-
A)
Design a circuit that utilizes one switch to turn on 2 motorsand another switch to turn off both motors. Pressing and releasingPB1 will turn on motor 1 immediately and motor 2 after a 3 seconddelay. Pressing and releasing PB2 will turn off both motors.
B)
Next, design a circuit that utilizes 1 switch to turn on 3motors. Pressing and releasing PB 1 will turn on motor 1immediately; motor 2 will turn on 2 seconds after motor 1 and motor3 will turn on 5 seconds after motor 1 but only if motor 1 andmotor 2 are already running
Use 1 switch (press and release) to turn off motor 3 only andone switch (press and release) to turn off motor 1 and 2. If motor1 or motor 2 turn off, motor 3 should also turn off.
Part 2-
For this part you will utilize 2 or more timers to create anadjustable duty cycle waveform that is on for 2 seconds and off for3 seconds. Use a momentary (press and release)push button or toggle switch to enable (start) the waveform. Youcan use the EN or DN bit from one of your timers, tied to an output(OTE) to emulate the waveform output or you can create a simplelatch circuit using a bit or OTE.

Part 1A On Pressing PB1 motor 1 M1 turns ON immediately and thelatching coil A picks up which holds the NO contact A in closedposition At the same time the timer TON starts and after 3 secdelay DN bit gets high which turns ON motor 2 M2 As thelatching coil is picked up therefore even after releasing PB1 themotor and the timer TON will still run On Pressing PB2 See Answer
