![]() ![]() The board is powered by supplying 12V from our wall plug to V in of the Arduino board you are using. ![]() The safest solution is to use a 5V regulator before connecting to the RAW input pin. WARNING: An Arduino Pro mini clone might not be able to take in 12V. That is designed only to power the board and is not capable of withstanding the large current draw the window needs. WARNING: The DC plug pictured below is not the one on an Arduino UNO board. I used a DS1307 module pictured here, and you can buy one off AliExpress for about $0.50. I needed a IRLB8721 MOSFET ($1) to control the brightness and the current, and finally some breadboard wires, a DC female plug and a 12V DC charger ($5) to complete the package. I also happen to have a 5m strip of warm LEDs that I bought off AliExpress for $4.41. So instead, I used an Arduino Pro Mini (5V) that was being sold for $4 in Microcenter. However, using a Raspberry Pi in my case is kind of an overkill because I want to wake up at the same time every day. This project uses a Raspberry Pi to control the lights, and turn them on and off as required. So this proves that using LED behind blinds can actually create a nice simulation of daylight. The Smart LED window creates a sunlit basement. There are also other projects that aim to create some sort of artificial light. ![]() I can have morning at whatever time I want. I don't have the capability to manufacture something like that, but I am able to mess around with LEDs, and I figured a better way to do this than having a morning light is actually simulating sunrise: make it so that my window lights up as if it was daylight outside. That is a little more expensive than what I want to spend on a light that gradually lights up in the morning. A more expensive version with a colored sunrise simulation costs $139.99. One of these things at the moment costs $49.99 (with a $20 coupon applied). I noticed that I often would shut off the alarm and go back to sleep, and waking up was kind of rough. There are many (claimed) benefits to having a Sunrise or Wake-up light, one of which includes a gentler wake-up as compared to the loud buzzing of an alarm in the darkness (true). I've always wanted to build one of these: Figure 1. Turns out, it wasn't very hard or expensive. Hearing so much about the Philips Wake-Up alarm made me wonder how hard it was to build one given its rather high price. I have trouble waking up on gloomy winter days. ![]()
