Customizing Pins and Their Functions
The flexibility of pin control allows users to reconfigure pins to better suit their needs. By accessing a pin setting menu, users can redefine pins or allocate them for specific purposes. This feature proves useful when you want to change a pin’s functionality. For example, if one pin is no longer required as an input, it can be shifted to an output role for tasks like generating square signals through pulse width modulation.
Setting Timers and Adjusting On/Off Times
In addition to the input/output roles, pins can serve as timers. By utilizing timers T1 and T2, users can set specific on/off times for each timer. This functionality enables precise control over the timing and synchronization of various device operations. Whether adjusting timers through analog reads or fixed values, pins allow users to finely tune the behavior of their devices.
