Pinout Description
The Third Hand Tool with Magnifying Glass is an IoT component designed to assist with PCB assembly and repair tasks. It features a built-in magnifying glass and a set of adjustable arms to hold components in place. This documentation provides a detailed description of the pins and their connections.
Pinout Structure:
The Third Hand Tool with Magnifying Glass has a total of 6 pins, arranged in a single row. The pins are numbered from 1 to 6, starting from the top-left corner.
Pin Description:
1. VCC (Pin 1):
Function: Power supply voltage input
Description: Connect the positive terminal of your power source (typically 3.3V or 5V) to this pin.
Recommended wire gauge: 20 AWG
2. GND (Pin 2):
Function: Ground voltage input
Description: Connect the negative terminal of your power source to this pin.
Recommended wire gauge: 20 AWG
3. LED+ (Pin 3):
Function: LED anode (positive leg)
Description: Connect the positive leg of the built-in LED to this pin. The LED is used to indicate the device's status.
Recommended wire gauge: 22 AWG
4. LED- (Pin 4):
Function: LED cathode (negative leg)
Description: Connect the negative leg of the built-in LED to this pin.
Recommended wire gauge: 22 AWG
5. Sig (Pin 5):
Function: Signal input/output
Description: This pin is used for communication between the Third Hand Tool and other devices. Can be used for I2C, UART, or other serial communication protocols.
Recommended wire gauge: 24 AWG
6. EN (Pin 6):
Function: Enable input
Description: Connect a digital signal to this pin to enable or disable the Third Hand Tool's arms. A high logic level (e.g., 3.3V or 5V) enables the arms, while a low logic level (e.g., GND) disables them.
Recommended wire gauge: 24 AWG

 Breadboard and jumper wires
 LED indicator (optional)

Code Example (Arduino)
```c
#include <ThirdHandTool.h>

ThirdHandTool thirdHand;

void setup() {
  thirdHand.begin();
  pinMode(LED_BUILTIN, OUTPUT); // optional LED indicator
}

void loop() {
  // Adjust the magnifying glass to focus on a small object
  thirdHand.setMagnification(2.5);
  thirdHand.setArmAngle(45);

// Inspect the object and take a measurement
  int measurement = takeMeasurement();
  Serial.print("Measurement: ");
  Serial.println(measurement);

// Release the object and move to the next inspection point
  thirdHand.releaseObject();
  delay(500);
}
```
Example 2: Quality Control Inspection with Python

In this example, we will create a Python script to control the Third Hand Tool with Magnifying Glass and perform a quality control inspection on a production line.

Code Example (Python)
```python
import third_hand_tool
import time
import cv2  # optional

# Initialize the Third Hand Tool
third_hand = third_hand_tool.ThirdHandTool()

# Set the magnification and arm angle for inspection
third_hand.set_magnification(3.0)
third_hand.set_arm_angle(60)

while True:
    # Capture an image of the object (optional)
    img = cv2.imread('image.jpg')
    # Perform image processing to detect defects (optional)
    defects = detect_defects(img)
    if defects:
        print("Defect detected!")
        # Take a measurement or perform another action
        measurement = take_measurement()
        print("Measurement:", measurement)
    else:
        print("No defects found.")

# Move to the next inspection point
    third_hand.move_to_next_point()
    time.sleep(1)
```
