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.
Comand Board MCU ATMEGA2560 (Mega 2560) Encoder For seting the flow rate, starting and stopping the motor, and opening screen with sensor values. LCD Display Show sensor values. TB6600 Stepper motor driver. Motor Stepper motor for controlling the flow of the syringe. BME280 Sensor for monitoring temperature, pressure, and humidity. Power Supply MCU power supply.

Questions

How big is the Electrical design PCB?

It measures 55.5 × 60 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Electrical design use?

27 parts, built around the 1N4148WS, FDB13AN06A0, IRLZ34N and PEC11R-4215F-S0024. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Electrical design KiCad files?

From the NCMST/Electrospinning-device repository on GitHub, at the commit this page was made from: the board is Hardware/Electrical design/Electrical design.kicad_pcb and its schematic Hardware/Electrical design/Electrical design.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Electrical design design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
