RTC-4Relay timers v.01. Alfonso Abelenda Escudero 2018
Pinouts:
ZS-042: SDA-A4(PC5),SCL-A5(PC4),SQW-pin 2 (PD2)
Purpose:
This sketch demonstrates how to use the ZS-042 RTC and a 4 way relay module to swtih the relays in a timely programmed way using the serial port to set the alarm and timer parameters.
Features:
Eight configurable daily alarms, eight cycling timers to swith relays on and off. Scheduled weekly day off for each alarm, scheduled yearly holydays that can be launched only one day if wanted. Configurable via TTY console on arduino serial port, reset to alarms defaults, display of several status, and setting RTC time commands available.
TODO:
TODO: routine to change EEPROM cell when they reach their writes lifespan, that can be around seven years.
TODO use AT24C32 EEPROM to get advantage of its 1M cicles of rewriting. 32Kb 1M rewrites. Seven decades of use per register writing one every minute.
TODO more actions doable with timers.
TODO: LCD display routines.
TODO: Make something useful with the RTC alarms.
TODO: portable control GUI in Win, Mac and Linux.
