CS250 Lab 4

Introduction to Microcontrollers / Implementing a Temperature and Light Alarm

Grading Form

Goal

In this lab you will get familiar with the Arduino Board and Microcontrolers. The Arduino board is an easy to use microcontroller platform that you can use to interact with the physical world. In this lab you will do a few small projects to get familiar with the Arduino and then you will implement a temperature alarm.

Step 1. Introduction to the Arduino

Read the "Arduino Inventor's Kit" documentation pages 1 to 7. Also, install the Arduino IDE if necessary (the machines in the lab already have it installed) and then implement and test the following circuits:

Circuit	Implemented and Tested (Write a checkmark)
Circuit 1: Blinking LED
Circuit 7: Push Buttons
Circuit 8: Potentiometers
Circuit 9: Photoresistors
Circuit 10: Temperature
Circuit 12: RGB LEDs

Do as many of these circuits as you can during the lab and then complete them at home. You can copy and paste the code but make sure that you understand what it does. You will need this knowledge to implement the next step and future projects.

Step 2. Building a Temperature and Proximity Alarm.

For next lab bring a circuit that will turn on the RGB LED

Turn on RED -

When the temperature is above a preset temperature (choose the preset temperature so it can be easyly changed by touching the temperature sensor)

Turn on BLUE

When the photoresistor and the light source is interrupted.

Turn on GREEN

Otherwise

For Your Next Lab

For your next lab make sure you implemented and tested all the circuits from step 1 and the table is completely check marked. Also, bring the implementation from Step 2.
