I have a 240v incandescent bulb lamp that I want to be able to use as a sunrise alarm. I want to be able to have it turn on, but slowly increase in brightness over a set time, so that it mimicks a sunrise.
I currently have a solution that was created by another freelancer in a project I posted 9 months ago.
It currently is setup via an arduino running an external RTC module and a dimmer module like this one [login to view URL] and works ok. I have two probelms with it I would like to improve.
[login to view URL] RTC module seems to slowly lose time and therefore the alarm is no longer accurate.
2. There is no easy way for me to change the alarm time. I have to change the arduino code and re-upload it.
I would like to find a better solution. Perhaps using a raspberry pi or similar with and internal clock and either use an LCD screen or a locally hosted web page to be able to change the alarm time. I would also like to be able to set the initial brightness and final brightness as a percentage. And also set a time to ramp up from initial to final brightness.
I am seeking assistance to create a system to achieve my goal. I am paying for your expertise and design skills. I can build your solution myself. Please quote for delivery of plans for a workable solution.
