Utilizing a **PIC24F16KA101** microcontroller, the device is programmed to display measurements on a serial monitor. The project is built on a breadboard and programmed with **MPLAB X IDE** using **PICkit 4** as the in-circuit debugger. Readings are outputted via **UART2** to the **Tera Term** terminal application.\n\n\u003cp float=\"left\"\u003e\n    \u003cimg src=\"https://github.com/user-attachments/assets/4334f520-179e-4b27-acb5-562d87c9e302\" width=\"40%\" /\u003e\n    \u003cimg src=\"https://github.com/user-attachments/assets/d1b3fbbb-4d11-403d-99c4-af486004daa9\" width=\"40%\" /\u003e\n    \u003cimg src=\"https://github.com/user-attachments/assets/0c25de30-1d48-4138-bb6e-d3c715fd31cf\" width=\"48%\" /\u003e\n    \u003cimg src=\"https://github.com/user-attachments/assets/85548441-6c01-4575-aacb-3280c960834a\" width=\"20%\" /\u003e\n\u003c/p\u003e\n\n## Features\n- Voltage Measurement: Reads and displays voltage on a connected component.\n- Resistance Measurement: Calculates and outputs the resistance of a component.\n- Capacitance Measurement: Measures capacitance values using a CTMU (Charge Time Measurement Unit) approach.\n\n## Code Overview\nThe project’s code includes several critical files:\n\n- **main.c:** Initializes the microcontroller, including clock and peripheral settings, and handles the measurement loops.\n- **UART2.c:** Manages UART2 communication functions, including data transmission and interrupt handling.\n- **IOs.c:** Handles input/output configurations, such as pushbuttons for triggering different measurement modes.\n- **ADC.c:** Reads and processes the analog-to-digital conversions necessary for voltage and resistance measurements.\n- **CTMU.c:** Configures and utilizes the CTMU module for capacitance measurement by timing charge and discharge cycles on the capacitor under test.\n\n## Demonstration Video\nClick below to watch a demonstration of the project\n\n\n[![Demonstration Video](https://github.com/user-attachments/assets/90aa8bca-837c-4dd6-8958-179c4961deab)](https://www.youtube.com/watch?v=2IUto0paSR4)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmushtabaa%2Fmicrocontroller-based-digital-multimeter","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmushtabaa%2Fmicrocontroller-based-digital-multimeter","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmushtabaa%2Fmicrocontroller-based-digital-multimeter/lists"}
