Arduino "Selbstschussanlage" - Der Bastelbunker

Da ich auch mal was mit einem Servo bauen wollte,

habe ich eine kleine „Selbstschussanlage“ in 2 Versionen gebaut .

Es wurden hierfür verwendet:

Arduinio Uno
Laser aus einem alten Laserstift
Modellbau Servo
HC-SR04 Ultraschallsensors

Viel Spaß damit ;o)
