#Digital alarm clock mini project code

So, let's get started with DS1307 Arduino based Digital Clock in Proteus ISIS: DS1307 Arduino based Digital Clock in Proteus In this way, you will learn more out of it. Instead design your own simulation and try to write your own code.

I have given the Simulation and Code for download below but as I always advise, don't just download the files. So, now I hope that you have installed both these libraries successfully and are ready to design this DS1307 Arduino based Digital Clock.

Along with Arduino Library you will also need to install DS1307 Library for Proteus, which I have shared in my previous post as we are gonna use this RTC Module DS1307 for designing our digital clock. So, first of all, if you haven't yet installed then, you should install Arduino Library for Proteus using which you will be able to easily simulate Arduino baords in Proteus. In this project, I have designed a digital clock using Arduino UNO and DS1307 RTC Module. I have to admit – it isn’t that bright in reality but it’s still very readable although it is so large.Hello everyone, today I am going to share a complete project which is DS1307 Arduino based digital Clock in Proteus ISIS.

Here the projector with Walimex Pro 10mm 2.8 lens. Just for fun – and because I have a 3d printer which works reliably without much attention – I did a variant for Sony E-Mount.

The pillow-effect (optical distortion where the edges are not straight but bent outwards) is almost neglectable – resulting a much better image than I expected (after reading reviews to this lense) They are sooo cheap that image quality is really really bad when using for fotography.īut surprisingly it works (almost) perfect for the Mini DIY Projector 😀 There are incredibly cheap chinase C-Mount lenses with a focal length of 25mm. To be sure – actually I wasn’t really – I decided to use a high power LED with 1W and use a cheap chinese condensor lense to parallelize the light before it passes the LCD (this has do be done anyway but a condensor lens makes it possible to use more light because condensors are shaped in a way that allowes to get the lens as near to the LED as possible – so catching more light). It was not really clear how strong a LED has to be in order to get a reasonable well readable picture in the night on the ceiling. I decided to go for 25mm because there are cheap lenses which can be obtained for about $12 in china.įor our values that would magnify the image by about x80 – 11.1mm LCD width would become 88.1cm image width on the ceiling in a distance of 2m. The formulas show that the smaller the focal length the larger the projected image will be. The formula for image width depending from the focal length is defined as: A good distance would be 2m from LCD to ceiling. Moreover a smaller LCD needs smaller focal length for a decent sized imaged on the ceiling. The goal was to build a complete projector with not more than 50mm x 50mm x 50mm (which I didn’t managed … But close to^^).Ī small LCD has the advantage that everything becomes smaller and cheaper – this influences heavily costs for optics because a smaller LCD needs smaller optics to project an low distorted image. I choosed a small negative (background black) 64×32 LCD which has the dimensions of just 15mm x 12mm (active area 11.18mm x 5.58mm). The principle is easy – basically it works like a video beamer (or any other projecting clock^^). Moreover it was a good project for becoming accustomed to the process of 3d-designing cases which can be 3d printed and to learn about designing tolerances. There are lots of commercial alarm clocks with integrated clock projector on the market but I thought, it would be fun to build one myself. A Clock Projector can project the time to a ceiling in the night.
