Arduino Week 03

This week we start with Project 07 in the Arduino Starter Kit and built a Keyboard Instrument. This project utilizes a process called a resistor ladder. A resistor ladder is a circuit that is made using repeating units of resistors. This way we can read multiple switches using only one analog input. Again we are using the tone() function, but this time we are storing specific frequencies and playing them based upon that analog input from the resistors. Here is Corey playing his instrument…

Project 08 has us building a Digital Hour Glass. Using the mills() function we can count time and turn LED lights on sequentially. Then with the tilt switch we can reset the clock and the LEDs when the breadboard is physically moved. Here is Kristen’s Digital Hour Glass at work…

The assignment for the week is Project 09: Motorized Pinwheel
