- Draw the truth table,according to the given below The alarm circuit in a car is controlled by 5 switches. These are:A: ignition switch, B: driver,C: driver's belt, D: front passenger andE: front passenger belt. Switches are initially in the off state. Switch A opens in the ignitionstate. When the person sits, the relevant key opens. If the belt isattached, the relevant key opens. Design the circuit that will alarmwhen the car is moving and any of the front seats are occupied and theseat belt is not fastened.Q3 /A)- Design an electronic circuit to drive Four (4) LEDs by using 741 Op-Amp. The internal resistance of each LED is 70 ?. The 741 Op-Amp can carry out maximum output current 20 mA, and requires minimum voltage of 5 V. After completing your design explain why used this kind of connection in your design ( you can use Ohm’s Law in yours explanationArduino#2 is connected to the following components:1- Switch : the switch will control if the system works in Automatic mode or manual mode. If in automatic mode then all work will be done automatically by Arduino#1. If in Manual Mode, then Arduino#2 will receive different alarms about the situation of Arduino#1, and use remote control to turn on/off the bulb, the door (servo motor), and the fan (DC motor).2- LEDS and Buzzers to notify the user if anything needs an action (in case of Manual Mode).3- Remote Control: to control all the actions (in case of Manual Mode).
- It asks to use a system that reads an IR keyboard, and if pressed:button 1 turns on a spotlight and sends the message to an LCD: Garage spotlight onbutton 2 turns off the light and sends a message to an LCD: garage light offbutton 3 activates an ultrasonic sensor and if it detects something within 1 meter, it activates a buzzer and a message onLCD screen: intruder detected.And if the alarm is activated it can only be stopped with the red button of the IR keyboard. The circuit is shown belowA gate can be in one out of four possible states: closed, raising, open, lowering. The gate can be opened either manually (by pushing the “OPEN” button) or when a sensor detects that a car is at gate. After the gate fully opens, it can be closed by pushing the “CLOSE” button. It can be also closed after 10 seconds from being fully opened, but only if there is no car at gate.Create state transition table for the above case based on the image given.Your output port is connected to 8 LEDS. You wish to turn on the two LEDS located at the outside of the LED pack (the first LED and last LED), so you send the hex number to to port. 00 O 11 18 O 55 81
- Purpose: The entry/Exit of the parking lot is a single lane passage. By controlling the indicators, the program ensures that only one car can pass through the Entry/Exit so as to prevent car accident between entering and leaving cars. Y1 X1 Program Description: In the parking lot, there are two light indicators individually directing the entering and leaving cars. By the interlock control circuit, only one indicator will show "GO" signal and the car accident will thus be prevented. When an the same time, the leaving car indicator will show "STOP". Car entering is allowed but leaving is prohibited in this case. When a leaving car draws near the vehicle control barrier, X1 will be ON and so will Y1. The leaving car indicator will show "GO" and the entering car indicator will show "STOP"| draws near the vehicle control barrier, XO will be ON and so will YO. The entering car indicator will show "GO". At TOP GOWhat is a transparent latch? Why is it necessary to latch with output devices such as LED's?Control 2 red and blue LEDs flashing alternatelyWhen one light is always on, the other light is off

Use an LED of your choice for the lighting. Create the circuit such that the LED is turned ON when your hand is above the photoresistor and turns OFF when your hand moves away from the photoresistor.Draw a ladder diagram that will have the following results: a. Lamp L2 and Lamp L3 deactivated while Lamp L1 activated the moment power is turned ON. b. Lamp L1 and Lamp L3 deactivated while Lamp L2 activated when switch S2 is pressed and released. c. Lamp L1 and Lamp L2 deactivated while Lamp L3 activated when switch S3 is pressed and released. d. Lamp L2 and Lamp L3 deactivated while Lamp L1 activated when switch S1 is pressed and released.
