Arduino Lab 2

Try out some Arduino programs from the Arduino Examples page.

• Blink an LED. The LED is already on the board. Vary the rate of the blinking. Cycle between slow blinks and fast blinks.
• Printing on the serial port.
• Read a switch. You'll need to use wires and resistors for this.
• Blink an LED. This time add an external LED. Be sure to use a current limiting resister. Go with 330 Ω. That's safe and we have a bunch of them. Also, learn about the resistor code.
