Answer 2

Analog port

Question 3

How many LEDs does the IP sensor have on it

Answer 3

2

Question 4

The purpose of the Arduino Uno

Answer 4

The arduino uno is a microcontroller board designed for controlling electronics. It can be programmed to read voltages or give voltages to turn devices on or off

Question 5

how many digital I/O ports does the Arduino have , what is their primary function?

Answer 5

It has 14 digital poets which can be configured as either input or output to read data from sensors or control external devices

Question 6

The purpose of the delay() function in Arduino programming

Answer 6

The delay() function pauses the execution of the program for a specified ount of time, allowing for controlled timing un tasks such as blinking LEDs or controlling the frequency of sensor readings

Question 7

identify the error

Answer 7

the error is that the setup function is missing the declaration 9f pin Mode for pin 13 as an output. It should be pinMode (13, OUTPUT) in the setup function
