I have an Arduino Mega with a DS3231 Clock, a DHT22 Temperature/Humidity Sensor and a relay board. I also have a Nextion 3.5" programable touchscreen display.
I would like the code for the programable screen and Arduino to control a vivarium temperature, humidity and lighting by turning on and off a halogen daytime heating lamp, UV tube, night time heating lamp and humidifier.
The home screen on the Nextion display should display the current time/date, temperature and humidity and have 4 buttons. Day / Night / UV / Humidity. Each of the buttons should lead to a new page. Each of the pages should have a return to the home screen.
The 'Day' page should allow the time that the halogen heating lamp (via relay 1) is turned on/off and also the temperatures that it should be turned on and off to be set.
The 'Night' page times should also be the day times in reverse (on day = off night and off day = on night). This should allow the temperatures that the night heat lamp (via relay 2) is turned on/off.
The 'UV' page should allow the on/off times to be set for the UV lamp via relay 3.
The 'Humidity' page should allow the on/off times for the humidifier to be set as well as the upper and lower humiditys. Via Relay 4.
The libraries and details for the components can be supplied.
The pin numbers and connection details for the Arduino should be specified
