This GitHub repository contains an Arduino project that serves as an interface between an Arduino board and a micrometer caliper through a serial connection. The code enables communication with the micrometer, allowing the Arduino to retrieve and interpret measurement data. This ReadMe provides a detailed explanation of the project's key components.
The micrometer's communication involves three lines connected to specific Arduino pins:
- REQ (Request): Connected to Arduino pin 5.
- DAT (Data): Connected to Arduino pin 2.
- CLK (Clock): Connected to Arduino pin 3.
The setup() function initializes these pins using pinMode and sets the initial state of the REQ line with digitalWrite(req, LOW).
Serial communication is established with the Serial library at a baud rate of 9600 (Serial.begin(9600)). This allows the Arduino to communicate with an external device, typically a computer, through the serial port.
The loop() function is responsible for retrieving data from the micrometer. It generates a request signal (digitalWrite(req, HIGH)) and reads the data bits from the DAT line based on the clock signal from the CLK line. The received data is stored in the mydata array.
The code interprets the data, extracting information such as sign, value, decimal position, and units. The measurement information is then converted into a human-readable format.
The interpreted measurement value is printed to the serial monitor, considering the sign, value, and decimal precision. The code supports both positive and negative measurements.
- Connect the micrometer's REQ, DAT, and CLK lines to the specified Arduino pins.
- Upload the provided code to the Arduino using the Arduino IDE.
- Open the serial monitor to observe the interpreted measurement values.
Users can customize the code to adapt it to specific micrometer models or communication protocols. Additionally, adjustments to the code can be made to match the baud rate of the micrometer.
Contributions and improvements are encouraged. If you encounter issues or have suggestions for enhancements, feel free to open an issue or submit a pull request.
