When our robot find out that the baby’s diaper is wet, she will blink her eyes, shout out loud (it helps as well for the visually challenged). At the same time, if you are watching movies downstairs or in your neighbor’s house, it will send you an email or text message.

In our project, when our phone receives a text message or email from the robot, it will alert you to change baby’s diaper and play a cute baby crying sound, downloaded from the Internet. Click here to hear or download it

We ended up returning the kit from radio shack as we saw a better one at Amazon.com at  http://www.amazon.com/Elenco-AmeriKit-Learn-Solder-Kit/dp/B0009Z3JJA ($14.62) (Now it is $15.44):

Product Features:
Includes solder, a soldering iron and wire cutters
Use for all your electronics soldering needs
Soldering required
From Elenco, offering the best selling Snap Circuits line of electronic educational kits

So far our parts cost for the project is $68.61. ($53.98 for Budget Pack for Arduino (Arduino Uno R3) Item# Uno w/328, plus $14.63 for Elenco AmeriKit Learn to Solder Kit – Elenco Electronics Inc.)

Since we’ll put LEDs as eyes for the robot, we’ll have to do soldering work. It is the process to put the wires and parts together in a permanent way.

A soldering kit from radio shack like the following will be used in our project:

It comes with soldering iron, some solder, and a mini stand to hold the iron.

Budget Pack for Arduino (Arduino Uno R3)

It includes:

  • Arduino Uno w/Atmega328 – The latest and greatest Arduino revision R3, assembled and ready to go, including 4 rubber feet to protect the board from the worktable
  • 3′ USB cable – Perfect for connecting your Arduino to a computer
  • Half-sized Breadboard – 400 connection points, plenty of room for beginner projects, with 2 power rails on the side. Can be rubber-banded to an Arduino to make a 1-penny devboard
  • 75 flexible breadboard wires in 8 colors, perfect for use with the solderless breadboard.
  • 1K & 10K potentiometer – these pots have 0.1″ spacing and fit very nicely into a breadboard without modification
  • 2 small pushbuttons – Snap into the breadboard for button inputs
  • 5 bright red diffused LEDs (250mcd) – indicators, blinkies, bright enough to see in the day, but diffused so that they are visible from all angles.
  • Red, green and blue ultra-bright LED – Can be used on their own, or color-mixed to make nearly any color in the rainbow!
  • 5 100 ohm resistors – They can be used to protect pin outputs when starting out
  • 5 1K resistors – Good for use as LED limiting resistors
  • 5 10K resistors – Great for pullups & pulldowns
  • CdS photocell – A light sensor!

Here is an excellent tutorial (a little outdated, though) to get you started:

http://www.ladyada.net/learn/arduino/

Lesson Plan:
Follow these lessons to get started

•Lesson 0
Pre-flight check…Is your Arduino and computer ready?
•Lesson 1
The “Hello World!” of electronics, a simple blinking light
•Lesson 2
Sketches, variables, procedures and hacking code
•Lesson 3
Breadboards, resistors and LEDs, schematics, and basic RGB color-mixing
•Lesson 4
The serial library and binary data – getting chatty with Arduino and crunching numbers
•Lesson 5
Buttons & switches, digital inputs, pull-up and pull-down resistors, if/if-else statements, debouncing and your first contract product design.
•Lesson 6
LEDs in more detail, Kirchoff’s Voltage Law, Ohm’s Law and a peek at the potentiometer
