Robotics is a sub-domain of engineering and science that includes mechanical engineering, electrical engineering, computer science, and others. Robotics deals with the design, construction, operation, and use of robots and computer systems for their control, sensory feedback, and information processing.

RC Switch

RC switch converts hobby radio control pulses to digital on/off signals and has an integrated small, low-side MOSFET that allows it to drive small loads (up to around 3 A), such as lighting or small actuators. The Pololu RC switch with medium low-side MOSFET can be used with standard hobby radio control systems for radio control switch applications or simple interface applications. Example uses include converting extra RC receiver or servo controller outputs to simple high/low signals that can control LEDs or relays and connecting RC systems to microcontroller projects that do not have the necessary resources for decoding the RC interface. The switch also features a flyback (or freewheeling) diode across the load outputs so that you can connect a coil to them, such as a motor or relay, without any additional external components.

RedBot Buzzer

RedBot 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.
