Introduction to Arduino and Physical Computing

Description

Make 3 LED lights blink at the same time with high/low less than 1 second. 

Components Used

1- Arduino Uno

1- Breadboard

1- 220 Ω Resistor

1- Green LED

1- Blue LED

1- Red LED

Description

I used Arduino with a green LED. I changed the code to lighting up for 2 seconds and then off for 4 seconds. Uploaded the code and made sure that it has changed.

Description

The purpose of this lab was to get the Arduino environment set up and to use an example program for the Arduino to blink an LED. The code was then modified to blink three LEDs simultaneously every 500ms.

Description

Initially, in class, I set up the circuit with 1 green LED, and edited the code to make the LED blink faster, with a 0.1 second flash-delay cycle.

I then re-created the circuit with two LEDs, green and blue, and changed the code to make the two LEDs blink with variable speed. (green with a 0.1 second flash-delay and blue with a 1.0 second flash-delay cycle).

Description

When trying out the blue LED, I was impressed by the intensity of light. I wanted to be able to turn it down and so rather than just make the light blink, as per the sample code, my code slowly pulses the light using the analogWrite command.

Description

This lab consisted of three steps: install the arduino environment on my computer, set up an LED on the breadboard, and change the blink example sketch to have the LED blink at my own rate. The LED is grounded with the green wire, and connected to a 220 ohm resistor, which leads to the arduino through the orange wire.

For this assignment, I made two LEDs blink, one at half the frequency of the other.

Assignment # 1: Blink LED

Description

As it was my first experience making an Arduino board, I followed the BLINK example under the File / Examples / Basics  folder by setting blinking time for 0.1 second, then turn off for 5 second, repeatedly.

Components

1. Arduino UNO

2. Breadboard

3. Red/Red/Brown/Gold Resistor

4. Green LED

Code

For this assignment, I created a blinking LED display by running a simple circuit through a single LED light from an Arduino UNO board.  I used a provided code sketch to cause the light to blink on and off in intervals of one second, then modified the code (see below) to create a sequence of two short blinks and one long blink.

Components used:

1 Arduino UNO Board

1 Breadboard

1 220-ohm resistor

1 LED light

1 USB Power Supply
