Introduction
The counting module is a kind of function module that can be used to do calculation. Combine this module with others to realize more complicated functions, like timer, etc.
The counting module has four modes that can be selected via the on-board swtich.
Up mode: the count is increased by 1 each time a high pulse signal is input; range 0-999
Down mode: the count is decreased by 1 each time a high pulse signal is input; range 0-999
Value mode (Analog value): read and output the corresponding analog value; range 0-999
Volts (Voltage value): read and output the corresponding voltage value; unit: VApplication: counter, accumulator, etc.

Usage Description
The counting module can be used to realize calculcation function by receiving the high pulse signal from the input port. In calcaulation mode, if the reset pin received the low level signal, the calculation will be reset.
Principle
The counting module can realize some simple calculcation function. In Up mode, the count is increased by 1 each time a high pulse signal is input. And if the reset pin received the low level signal, the count will be reset.
Application
- Counter
Description: the counting module detects the status of the push button, the count is increased by 1 each time the button is pressed.
