Introduction When our team was initially assigned the task of transforming this project from a cinematography quadcopter to a more practical sensor quadcopter, we made the decision to redesign the frame. This decision was not taken lightly, but it was concluded that one of the reasons the drone had been unable to fly thus far

SjoelSim! Is a mixed-reality version of the popular and historic Dutch shuffleboard game “Sjoelen”. The circuit makes use of two HC-SR04 ultrasonic distance sensors to measure the X and Z velocity of a playing disc. In combination with a program built in the Unity Engine, it makes for a pretty good alternative to the real
This is a EASY arduino project that you could create to impress your teacher and friends. This project is an IR sensor-controlled garage door. It uses 2 Servo motor’s to move the garage door into an opened and closed orentation. The inferred sensor (IR) is effective and long range with a range of 1-5 meters. This project
