Some Examples of External Sensors for Microcontrollers
Build a Smart Home System
Now, let's begin a new circuit design in Tinkercad.
Add a component to the design by clicking on a component
Find the components that you will need for this project,
Now, you will add two resistors to the breadboard.
Continue by adding two LEDs to the breadboard and two PIR Sensors.
Next, wire the Arduino UNO R3 to the breadboard by connecting the
Then, connect the LED resistors to the Arduino digital pins 6 and 7.
Finally, to complete the connections, you need to connect PIR "Room 1" and PIR "Room 2"
Code Blocks
Tinkercad's visual code blocks are useful for creating programs
Let's take a look at some important blocks that you will use for this project:
Let's Take a Look at the Code.
Start the simulation by pressing the Start Simula�on bu�on to test your program.
Fill the empty boxes with the missing component names.
a. Match the items in the first row with those in the second.
What is the difference between digital and analog pins?
Search the Internet forthe main differences between the Arduino Uno and the Arduino Nano series. For what types of applications is each series used? Present your findings below.

Extend the Smart Home System to monitor 3 rooms.
Change the Smart Home System so that it has 2 LEDs (1 red and 1 green) and 1 PIR Sensor. When the PIR sensor detects motion, only the green LED will be turned on, and when it does not detect
