![]() Optional: The 3rd is the schematic for the LED strip.The second one is the DS3231, button, potentiometer and the speakers.This also has the wiring instructions for the crystal on the arduino. The first one are the GLCD pins along with the ST7565. ![]() It saves a lot of damage from happening to the pins which only prolongs the project. I strongly recommend using headers on all the pins and IC sockets for all the pins. Arduino Leonardo (for other arduinos, uploading the code might be slightly different).Plywood (anything above 1/2" is fine, but the plans attached make use of 0.6" plywood) and assorted screws- maximum of 15$ (you can even use scrap wood) Potentiometers, knobs and buttons - $7.Female Headers and IC Sockets ( 1, 2) - A maximum of $5.Assorted Resistors - $10 (you can get them for much less as well).Multistranded Wire - At your local hardware store - Female AC Plug - At your local hardware store - Materials (Total Cost: $80 - you will probably have a lot of the smaller components already, this cost is an absolute maximum) I don't need the LED strip to wake me up as I can plug any nightlamp into the unit to do the same thing.įor more pictures and projects, please visit my blog at I was completely sold on the cardstock only after I turned on the LED strip, which, I think, looks nice through the cardstock. When I put a piece of cardstock printed black on the unit, covering all the sides with it, I thought that it looked better. However, I do realize that it should look better than that and so I experimented with some materials. The reason I wasn't able to sand the wood down properly is that it was all manual. Update: I got some feedback that the look of the front was quite bad initially because the paint brought out the defects in the wood. Therefore, I took a decision to turn them on completely twenty minutes before the actual alarm itself. While some people say that you need the light to slowly gradate in intensity, I found that low intensity LEDs were practically as good as turned off. The lights turn on twenty minutes before the actual alarm. But I think the end result is an alarm clock that actually lives up to the name. From the code to soldering to getting the right voltages for different components (3 different voltages specifically), this definitely was a difficult project. This project has been my single greatest learning experience since I started working with microcontrollers two years back. So I thought, why not build one? And then I got started. This project started with an article I read about how "dawn-simulating" clocks are far more effective at waking people up than just regular alarm clocks. As one of the dreamiest sleepers in the world, I have not found a single alarm clock (or a combination of them) that has ever been loud enough to wake me up permanently. Ever woken up in the morning, looked at your alarm clock, and wished you'd woken up about 5 hours earlier? I know I have.
