PLEASE HELP WITH PART A (FIRST SCREENSHOT) AND PART E (SECOND SCREENSHOT). Please explain the answer as well.

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.

Question 1 A microcontroller is used to control three LEDS in series (Blue, Red and White). Assume the current rating is 50mA. 1. Design an interfacing circuit for this purpose? 2. List the required components and illustrate their purpose? 3. What is the type of this interfacing?

. Does ‘a three digit color coding of resistor values’ limit producible resistor value ranges? Why? If you need to increase these range what would be your solution?   **please type it using keyboard NO handwriting**
