• Complete the functionality initiated in the videoUpdating Pulse Width Modulation (PWM) Duty Cycle Based on the Analog-to-Digital Converter (ADC) Sensor Reading.
• Average samples and send this over the Universal Synchronous Asynchronous Receiver Transmitter (USART) to a terminal.
• AddUSART_irq.c andUSART_irq.h files to our project (created in the earlier USART videos of this series).
• Open the main file developed earlier (AVR_USART.c) as an example reference to add the required variables and function calls to our project.
• Test that USART stdio is working in this project by sending "Hello World!"
• Send the average in a USART string from the ADC Interrupt Service Routine (ISR), completing the functionality that was introduced in the earlier videos.
