Relay control in real time using arduino and RTC. Used in Fishtank lighting, Plant irrigation.
Time values specified in structure ON - OFF sequence. Also manually can override ON/OFF sequence using Bluetooth. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Hardware: 1. 5V - 2 Channel Relay module on Normally Open configuration. 2. DS3231 RTC Module 3. HC05 Bluetooth 4. Arduino Micro 5. Jumper cables, prototype board, 230v Sockets and USB cable for powering arduino. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Time Schedule Eg:
// Total number of schedules #define NUMBER_OF_SCHEDULES 9
// Schedule timings: {ON hour, ON Minute, OFF Hour, OFF Minute} struct schedules stime[NUMBER_OF_SCHEDULES] = { {{7, 0}, {7, 45}}, //From morning 7AM to 7:45AM. 0.45 Total minutes {{8, 0}, {9, 15}}, //1.15 {{11, 0}, {12, 0}}, //1.00 {{13, 0}, {14, 0}}, //1.00 (1PM - 2PM) {{15, 45}, {16, 5}}, //0.20 (3:45PM - 4:05PM) {{16, 45}, {17, 0}}, //0.15 (4:45PM - 5PM) {{18, 0}, {18, 45}}, //0.45 (6PM - 6:45PM) {{19, 45}, {20, 0}}, //0.15 (7:45PM - 8PM) {{21, 0}, {22, 5}} //1.30 (9PM - 10:05PM) }; +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ files: *.ino - Arduino sketch. *.stl - 3d printable Board for accomadating Arduino, 2Channel Relay, RTC Module, Bluetooth & 2 Nos Socket.
