We kept working with random numbers to draw pictures.

Intro to the binary number system.
What kind of data can be represented in binary.
How the computer uses binary bits and bytes to represent different types of data.

Understanding the switch bounce problem-
Stratagies for fixing the problem-
Writing the code to fix bounce-

Create and debug program to toggle LED based on switch transition-

Schematic diagram of switch input-
Building the switch input-
Programming the LED state based on switch input-
How to modify the program to toggle the light-

The Arduino GUI-
The functions of the Arduino PC client-
How to write a simple program.
How to download and execute the program in the Arduino Uno.

Movies on hardware and software-
Movie on input/output devices-
Movie on binary data-
We covered what is the binary number system and what binary data is used for.

Electric circuits and Ohms law.
Exercises in measuring voltage, current, resistance-
What is a circuit? How to calculate voltage and current requirements.

Introduction to the Arduino platform, the Uno, design of the Uno, I/O pins functions, how it is connected to computer, etc.
Understanding I/O signal requirements. Basic electricity concepts: voltage, current, resistance and the relationship between them. How to use the multimeter to measure V, I, R with some exercises.

This was our first session together. We covered an overview of what a computer is and the purpose and design of the basic parts. Covered Input, Processing, Storage (memory), and Output. Watched movies about computer design and about circuits.
