Nano breadboard or weld all cables
Futaba servo S3003 x4
HC-SR04 Ultrasound sensor
Nuts M3 x20
Screws M3x12 x20
Powerbank (optional) or just use the usb for power the Arduino board.
Check the schematic picture for connection
The HC-SR04 Ultrasound sensor is not connected in the schematic; trig for pin 8 and echo for pin 9)
Using same original code for Arduino:
