The RedBot Buzzer is an add-on for the RedBot Mainboard or RedBot Kit that that gives your robot the ability to make noises, e.g. audible alerts or music. The buzzer works by making use of a digital I/O pin on the host controller board to create tones based on the frequency of I/O toggling. If you are using this buzzer on a RedBot, simply plug it into one of the 3-pin I/O ports (not A6 and A7 as those are input-only pins). Note: The maximum voltage rating of this buzzer is 4.5V, but the RedBot's digital output pins are 5V (as a standard Arduino). This may limit the life of the buzzer when used directly on the RedBot Mainboard. The RedBot Buzzer board measures 1.00 × 0.52 inches (25.33 × 13.37 mm) and has a 3-pin female header which connects directly to the RedBot Mainboard or via male-to-female jumper wires (not included). Use Arduino's standard tone() family of commands. Also, the RedBot Arduino Library includes example code and header files for using this buzzer. RedBot Buzzer Resources
