Electrospinning Device based on ATMEGA2560

This repository contains the source code, hardware schematics, and documentation for a device designed to facilitate the electrospinning process using the ATMEGA2560 microcontroller (Arduino Mega).

Features

The device provides the following features:

• Control and monitoring with BME280 sensor of temperature, pressure, humidity. And adjustable flow rate.
• FreeRTOS based task scheduler for easier and more efficient task management.
• High voltage source for electrospinning process.
• LCD display for monitoring.
• Motor for controlling the flow of the syringe. using driver TB6600.
• Encoder for user interaction.

Hardware Setup

The hardware setup consists of the following components:
The high voltage power supply generates the high voltage needed for the electrospinning process. It provides a stable and adjustable voltage source to create the electrostatic field required to draw the polymer solution into nanofibers. Varistor and Transformer convert the high voltage to the voltage required for electrospinning. Multiplier/Rectifier converts the voltage to the voltage required for the motor.
