Arduino-based cardboard robotic arm using four SG90 servo motors. Components
I used:
1 Arduino UNO 4 SG90 servo motors Cardboard for making the robotic arm Breadboard Jumper wires MALE TO MALE,FEMALE TO MALE,FEMALE TO FEMALE-20 EACH 4×AA battery holder and 4 AA batteries USB cable for Arduino connection to the computer Glue for attaching the cardboard parts ice-cream sticks
Arduino Connections: Base servo → D2 Elbow servo → D3 Shoulder servo → D4 Gripper servo → D5 adruino gnd to breadboard gnd adruino 5v to breadboard vcc+
