During the execution of an OUT instruction, the IO/M* signal will ________.   A) Go high. B) Go low. C) Not be used. D) Tristate

I have a wooden toy train that runs on wooden tracks. I would like to place two ESP-WROOM-32 Boards on top of the train. Broadcast communication (which involves radio frequency, not Wi-Fi) would help communicate about the train's lateness to five other wooden trains on the same track. Local communication would help communicate to the train station about the train's lateness. I would also need radio frequency Tx-Rx Modules for discharging and undergoing the signal, and repeaters just in case the signal loses power due to long-distance traveling. My wooden train should be automated. It should run at 4 inches per second, keep a minimum distance of 30 seconds away from the other wooden trains, and make a 17-second-long stop every 500 seconds. What's the procedure to connect the components? What's the Arduino code (C++) for this project?

The PLC-5, SLC 500, and MicroLogix use a(n) ____________________ instruction for moving data from one word to another.

Question : with Eight LEDs with 74HC595. This code uses a shift register to use a single data pin to light up 8 LEDs. The code uses the command "bitSet" to set the light pattern. What is the value of the variable leds when the value of currentLED is 5? Hint: You can use Serial.begin(9600) in the setup and Serial.println(leds) in the loop to examine this value. Answer must be a numerical value

Question 3: A very common application of electromechanical relay logic is motor control circuitry. Here is a ladder diagram for a simple DC motor control, where a momentary pushbutton switch starts the motor, and another pushbutton switch stops the motor: Start Stop CR1 CR1 CR1 Mtr Translate this ladder diagram into point-to-point connections between the following components (shown in the following illustration):

"Based on a source, book, or expertise in the specialized field, I need a solution to the question." Write an Arduino programming code that activates eight LEDs connected to pins 0 to 7 successively with an interval of 1 second when switch S₁ connected to pins 8 is turned ON, and all LEDs are activated when switch S₂ connected to pins 9 is turned off. (Hint: use array method).

Create a subroutine using registers AX and BX with POP instructions, that subtract two 16bit numbers. Make sure that you preserve the values of AX and BX for use by the calling routine. Assemble, test and show your code with the calling routine pushing the following values on the stack: Value one = 1234h, Value two =4321h Result (hex) = _________________ Result (binary) = _________________ Result (decimal) = _________________
