SparkFun ROB-12567 RedBot Buzzer
This buzzer is an add-on for your RedBot that gives your robot the ability to make awesome beep-boop noises or alerts when something interesting (or terrible) happens. The buzzer works by making use of two I/O pins on a controller board to create different noises based on the different frequency of I/O toggling. If you are using this buzzer on a RedBot, simply plug it in to one of the many 3-pin I/O ports and get your robot to make some noise.
The buzzer has a 3-pin header which connects directly to the RedBot Mainboard or via male to female jumper wires. Use the included RedBot library to detect sound alarms and make some noise.
