Guten Tag,
Ich habe noch wenig Erfahrung und baue aktuell einen kleinen Robotterarm der aus 6 Servos besteht nach Anleitung eines YouTube Tutorials. Das Problem ist, dass die Servos nur zucken und sich nicht bewegen. Ich kann sie nicht mit dem Handy über das HC-05 bluetoothmodul ansteuern, da sie nicht reagieren. Das handy lässt dich jedoch problemlos mit dem Bluetoothmodul verbinden. Ich weiß nicht ob es villeicht an der Stromversorgung oder an dem Bluetoothmodul liegt.

Schaltplan:
Auf der Zeichnung fehlt ein schwarzes Kabel das von der externen Stromquelle zum Bluetoothmodul bzw. zum Arduino geht.
Für die Stromversorgung verwende ich ein 5v 2A 10W Wandnetzteil von Amazon.
