    Arduino Launch Control System (LCS)

    Arduino Launch Control System (LCS)

    A single rod model rocket launch control system using the Arduino Nano

    This is a single rod model rocket launch control system. The system utilizes the Arduino Uno/Nano to report on local weather conditions (temperature, humidity, barometric pressure). The system also provides a 10-second countdown when the fire button is pressed. The system meets and exceeds the NAR Safety Code standard for model rocket launch systems as it incorporates a removable key to block the flow of power to the launch pad. It incorporates an additional two-button safety system to ensure that a launch is conducted exactly at the desired time. This release marks Version 1 of the system. It is designed to be modular so that it can be easily modified in the future. This project makes a great entry into electronics, Arduino and model rocketry. As such it is ideal for use in schools and youth organizations.
