Question 5 (20 Marks) You are asked to use the Arduino UNO development board to control different brightness of the LED. a) Sketch a simplified schematic diagram and draw wires to show how Arduino (UNO), LED, potentiometer, and (2200) resistor connect to perform LED brightness control. The circuit should be able to: Read the voltage passed through the potentiometer (in analog means); Monitor the input voltage level and convert to the output voltage level accordingly; Print the analog input level to the serial monitor; All components listed in the table must be used. →W Components W (3 Marks) Anode ☑ Cathode 1 x LED 1 x 2200 Resistor 1 x Potentiometer VIN FOX SV TX 1.31 8 AREF DE KOREF 06 RES 06 Arduino 222222 06 UNO 09 DI 011 012 1013 SOA SC b) 1x Arduino UNO Table 2: Component List for Question 5 (a) What is the usage of the 2200 resistor? What happens if you don't use a resistor with an LED? If the voltage source is equal to the voltage drop of the LED, is it necessary to use the resistor? (1+1+ 1 Marks)
