Introduction: Arduino Grab
If you have a 3D printer then... you must try to build one of this robotic arm-grab toy!
Step 1: What You Will Need - Hardware
For this project you will need:
Tip: You can use any Arduino board!
Step 2: The Circuit
The connections are pretty easy, see the above image with the breadboard circuit schematic.
Servo Motors:
- Servo for Grab movement to Arduino pin 6
- Servo for Rotate movement to Arduino pin 5
- Servo for Up/Down movement to Arduino pin 4
- Servo for Forward/Backward movement to Arduino pin 3
- All black cables to GNDAll red cables to Vcc - 5V
Potentiometers:
- for Grab movement to Arduino pin A0
- for Rotate movement to Arduino pin A1
- for Up/Down movement to Arduino pin A2
- for Forward/Backward movement to Arduino pin A3
- All left pins to GND
- All right pins to Vcc - 5V
Buttons:
- Teach button to Arduino pin 7
- Start button to Arduino pin 8
Buzzer:
- buzzer to arduino pin 9
Step 3: 3D Files and Assembly of the Robotic Arm
Step 4: The Code
If you want to disable the home position of your arm, just comment out the lines with "goHome();" command.
Note: You will need to change the min/max values for every servos to meet your setup.
