What setting should a dual-voltage selector switch on a power supply be set to while operating a computer in the United States?
Step by step
Solved in 2 steps
- What setting should a dual-voltage selector switch on a power supply be set to while operating a computer in the United States?The lights in a classroom are controlled by two switches: one at the back and one at the front of the room. Moving either switch to the opposite position turns the lights off if they are on and on if they are off. Assume the lights have been installed so that when both switches are in the down position, the lights are off. Design a circuit to control the switchesArduino programming exercises using Uno Microcontroller Write a program that starts out by flashing an LED connected to pin7 at 2Hz. On a button press (button is attached to pin4 – wire active low), the LED turns on for 2 seconds. After this the whole cycle repeats.
- Arduino programming exercises using Uno Microcontroller Write a program that turns on an LED attached to pin 3 for 5 seconds then turns it off. The light should stay off for 3 seconds and then the LED should blink 10 times at a rate of 1 Hz (on and off each second).A switch may be set to monitor the traffic passing via its ports.Arduino programming exercises using Uno Microcontroller Write a program that starts by having a red LED attached to pin 8 go on. The LED will stay on until a button is pressed. A half second after the button is pressed, the red LED will go off and a green LED will go on for 5 seconds. After this the whole cycle repeats.
- Describe a tiny "switch" that can be activated or deactivated with only one finger.Discrete Structures) A light is to be controlled by three switches, s1, s2, and s3. Switch s1 is an enabling switch. When it is in the on position, then the other two switches control the light. If the light is on, then flipping either s2 or s3 will turn it off, and if it is off, then flipping either s2 or s3 will turn it on. However, if s1 is off, then switch s3 is deactivated, and only switch s2 will control the light. Design a logic circuit that will make the switches behave in this manner.......Arduino programming exercises using Uno Microcontroller Write a program that lights a green LED attached to pin 3. The green LED should turn off after a button attached to pin 4 has been pushed and released 3 times. Each time the button is pushed it will turn on a red LED attached to pin 7 and turn off a yellow LED attached to pin 9. When the button is not pushed the red LED will be off and the yellow LED will turn on. Assume the button is wired active low. Turn on green LED Leave it on Turn on yellow LED Leave it on Check the state of the button If the button is pressed Add 1 to a counter variable Turn off yellow LED Turn on red LED After the button is pressed, turn on yellow LED, turn off red LED If the counter is 3 or more (>2) Turn off green LED
- design MCU system to control 4 leds (turning them on/off), keypad is used to enter the control command. When a new command is entered, it should be displayed on LCD. the keypad is a 4*4 please use arduino uno for this. also please include the code in text and the schematic diagram.A circuit has two pushbutton switches connected to pin PA2 and PA3 and two LEDs connected to pin PC0 and PC1 of the AVR ATmega16 microcontroller. Write a program to control the LEDs as follows; blink PC0 LED if the PA2 pushbutton is pressed with 2 seconds total delay time for every blink and blink PC1 LED if the PA3 pushbutton is pressed with 300ms total delay time for every blink.What parts are needed to assemble a control unit that uses vertical coding, and how is it built?
