Arduino Analog input and output

Please if the solution will be handwriting be clear

Introduction (2 marks) Describe the analog input pins. How many of these analog pins are there? What is the range of the input signal in volts that can be measured with these pins. What is the range of the digital form of the signal? How many bits are used to represent the equivalent digital number? Explain the PWM technique which is used to output an analog signal from the Arduino. What is the range of the PWM signal used by the Arduino? Task 1: Fading a LED using the Arduino Uno In this task, you are required to use the PWM technique in the Arduino Uno to make the brightness of a LED fades on and off at given rate. In the schematic shown, an LED circuit is interfaced with an Arduino Uno board as shown. PWM pin 9 is connected to the LED through a 30092 resistor. Arduino UNO 9 300 IH 1) Use the Tinkercad Circuits tool to construct the circuit. Copy the image in your report (imark) 2) Use the Tinkercad code editor to write a C-language code that would make the LED fades on at sampling time of 10 milliseconds. Copy and explain how the code is working. 11 mark) 3) Modify the code to fade the LED on and fade it off repeatedly pert sampling time of 10 milliseconds. Copy and explain the update code is working. (1 marks) 4) Modify the code to fade the LED on and fade off in at a rate of 5 digits per sampling time of 10 milliseconds. Copy and explain the update code is working.
