Hi,
I am trying to write a code that will open a box lid using a servo motor while setting off a buzzer at the same time each morning. I am working off of an alarm example by Paul Stoffragen: (TimeAlarms/TimeAlarmExample.ino at master · PaulStoffregen/TimeAlarms · GitHub)
I'm using an Arduino Uno, a DC buzzer, DS1307 RTC, SG90 MicroServo, powering the board from USB. I have the IDE 1.8.13 and am on Mac OS 10.14.06. I also tried the same code on a windows machine, and it made no difference.
I have successfully opened the lid and set off the buzzer using an ultrasonic sensor, but I am now having trouble figuring out the RTC so that it can happen at the same time each morning. I have used the "ReadTest" example sketch to confirm that the RTC has the correct time, but the MorningAlarm function does not seem to get triggered in the code below (I cannot get the servo and buzzer to activate). I have been testing this by setting the time in this line directly below to be a minute after I upload:
Alarm.alarmRepeat(2, 27, 0, MorningAlarm); // want to trigger MorningAlarm function 7:00am every day
The goal: At 7am everyday, the buzzer goes off followed by the servo arm moving from vertical (0) to 120 degrees to open the lid, wait a few minutes, then reset back to vertical (0).
I has used Arduino a little bit in school, but I've always had fairly detailed instructions to work off of, so I am definitely new.
Any and all suggestions are appreciated, thank you!
Alex
