Arduino Model Planetary Lander

The video tutorial explains how to create an Arduino-based Lander using an ultrasonic sensor and servo motors to deploy landing gear. Inspired by real planetary Landers, the project involves measuring distance to the ground to trigger landing gear deployment. The tutorial covers the design, circuit diagram, and code, using Tinkercad for simulation. It also discusses mechanical design considerations, such as impact absorption, and power supply decisions, emphasizing the importance of minimizing weight and protecting the Arduino.
