What is a digital/frequency input?

Digital Inputs allow a microcontroller to detect logic states if voltage is above or below a specific threshold level.

What is a analog input?

Analog input converts a analog signal into a digital value, thus can be later processed or / and stored.

What is a digital/pwm output?

Digital Outputs allow a microcontroller to output logic states. Output set to high will provide a voltage according the supply voltage of the mcu, like in our case about 5 volt. Output set to low will internal ground the pin and provide no voltage.
