6) Build an Arduino code that has keypad, LCD display. In this code you are required to: (Void Setup and Loop only) 1- Show "Hello Ardunio" blinking on LCD display with delay 1sec when pushing key I from the keypad and the LED is OFF. 2- Make a LED blinking with delay 1sec when pushing key 2 from the keypad and the LCD display is empty 7)An image of 250x250 elements (pixels) what is the memory size of the image if: a)Unit 8 b) Unit 16 c) Black & Whi 8) The game port register is used for two different purposes that are: 1- 2- 9) What is the FPGA device? 10) chose the correct answer for the following: 1- What is a result of connecting two or more switches together? a) The size of the broadcast domain is increased. b) The number of collision domains is reduced. b) The size of the collision domain is increased. c)The number of broadcast domains is increased.

1. Decide whether of the following statements is true or false. a. When only input 1 contact is activated, there is an output. b. When only input 2 contacts is activated, there is an output. Inputs 2 Output

QUESTION 32 The following code is used to create delay in a program: 0104 MOV BX, 0004 0107 MOV CX, FFFF 010A LOOP 010A 010C DEC BX 010D JNZ 0107 If you modify the code to set CX= 1FFF: O The delay will be increased and program will appear to run slower. O The delay will be decreased and program will appear to run slower. The delay will be decreased and program will appear to run faster. O The delay will be increased and program will appear to run faster.

Explain and draw a 7490 chip in a circuit of your own design. I want the actual chips drawn with the symbols inside, then a wiring diagram showing the interconnections. Power source and A, B, C, and/or D inputs may be added in the form of either buttons or switches.

Design a circuit that controls the passage of a signal "A" with the specifications: 1. Output X will equal A when control B and C are the same 2. X will remain HIGH when B and C are different. Hint: Set "A" input as a CLK pin.
