AVR Microcontroller Programming Guide

I need an intermediate-level programming guide for AVR Microcontrollers using MPLAB X IDE with MCC. This guide is for educational purposes.

Topics to cover:
- Basic I/O operations
- Timer usage
- ADC (Analog-to-Digital Converter)
- PWM (Pulse Width Modulation)
- LCD interfacing

The ideal candidate should have:
- Strong knowledge of AVR microcontrollers
- Proficiency in MPLAB X IDE and MCC
- Experience in creating educational content
- Ability to explain concepts clearly at an intermediate level
