Concept explainers

Stator and Rotor Magnetic Field

The stator and rotor magnetic field is the resulting magnetic field generated by a system of coils that are symmetrically aligned. They are supplied with polyphase currents. The magnetic field is generated by poly-phase (two or more phases) current or single-phase current. In the latter case, two field stator windings are supplied and two resulting electromagnetic fields are generated beyond the stage.

Design an encoding matrix with diodes and resistors to display a decimal number to on the seven-segment display. You have 10 switches (WO-W9) with one terminal connected to Vec. For decimal number 0, switch 0 (S0) is closed, for decimal number 1, switch 1 (S1) is closed etc. (Switches are on the vertical axis, S0 on top and the outputs are taken on the horizontal axis (Y0-Y6), with “a" on the left and "g" on the right. Note that (Y0-Y6) outputs are used as inputs to seven-segment display. Since these outputs cannot drive the seven segment display LEDS you may need additional bipolar transistors and resistors. The supply voltage is 5V and each LED needs a current of 20mA. Note that this is a design problem and the design is not unique. Do your best! f a a e
Demostrate obtaining 8 to 1 using 2 to 1 multiplexer using the IC 74157 IC. How the connection will be done?
I have two Arduino Uno Rev3 boards. One (named Alvin) is connected to an NRF24L01 module, two LEDs, and one Mini Pushbutton Switch. The other (named Brian) is connected to an NRF24L01 module, two LEDs, one DRV8833 DC/Stepper Motor Driver, and a 9V battery. I want to implement bidirectional communication between these two Arduino Uno Rev3 boards. Alvin must have its first LED on at all times unless the Mini Pushbutton Switch is pressed and unless Alvin receives a "Coming" message from Brian. If the Mini Pushbutton Switch is pressed, Alvin must send a "Hello" message to Brian. Brian must have its first LED on at all times. Brian's DRV8833 DC/Stepper Motor Driver must move at a PWM speed of 80. Unless Brian receives a "Hello" message from Alvin, Brian's DRV8833 DC/Stepper Motor Driver must take a 3-second pause every 12 seconds. 2 seconds before the DRV8833 DC/Stepper Motor Driver's 3-second pause, Brian must send a "Coming" message to Alvin. When that happens, Alvin must have its second…
