ArduinoTimer | adds configurable and asynchronous timer support

ArduinoTimer is a C++ library typically used in Internet of Things (IoT), Arduino applications. ArduinoTimer has no bugs, it has no vulnerabilities and it has low support. However ArduinoTimer has a Non-SPDX License. You can download it from GitHub.

arduinotimer is a library, which aims at providing developers with means to schedule asynchronous timer execution, pretty much like timer services provided by real oses. in fact, it is a set of libraries, one for each timer available in atmega2560 (1, 3, 4 and 5). by dividing the full library into four smaller libraries, the developer can save both ram and flash memory. the file arduinotimer.zip is a convenience for downloading all files at once :). library timer1 can be used with atmega2560, atmega168 and with atmega328. nevertheless, libraries timer3, timer4 and timer5 are exclusive to atmega2560. each library has nine functions: - void starttimer#(unsigned long microsecondsinterval): starts the timer, and schedules the first notification. on 16 mhz arduino boards, this function has a resolution of 4us, for intervals 262000, a resolution of 16us for intervals 1048000, and a resolution of 64us for intervals 4194000. on 8 mhz arduino boards, this function has a resolution of 8us, for intervals 524000, a resolution of 32us for intervals 2097000, and a resolution os 128us for intervals 8388000. - void startcountingtimer#(): starts the timer, but does not schedule any notifications. on 16 mhz arduino boards, the timer has a resolution of
