To help you with writing the code for your Smart Hospital Bed project, I'll clarify a few things:
Objective: Are you looking to write embedded code for the Arduino Mega2560 to control the various components mentioned in your schematic?
Functionality: What specific functionalities do you want to implement? For example, controlling the automated repositioning of the bed, reading data from sensors like the ADXL345 and infrared temperature sensors, or data communication between components.
Existing Libraries: Are you open to using existing libraries to simplify coding, such as libraries for the ADXL345 accelerometer or the MLX90614 infrared temperature sensor?
Communication Protocols: Are there any specific communication protocols you want to implement, such as UART for the Nextion display or I2C for sensors?
These clarifications will help me tailor the code to match your requirements effectively. Let me know, and then we can draft some code!
