Please note that it is convenient to but a Arduino of which the pins are already soldered to the Arduino. Since non of the components we use is resistant to water, the ip30 version is fine.
The 'ip' stand for the degree of resistance to water. For example, this will do: RGB led strip. RGB-led strip, 5 volt, 60 leds per meter, individually adressable.

If I find the time I will post an update about this!
Led word clock uk Bluetooth#
Recently, I developed a Word Clock which uses Bluetooth to set the colors and the time. However, since I want to keep it simple for now, this is not included in this Instructable. If you want to be able to change the colors of the leds in real time, you can add a button that does this for you. Besides, since we are using a RGB led strip, you can light up any letter in (almost) any color you want! You can set the color of the individual RGB leds by programming the Arduino Nano. Of course, the Word Clock should tell you the time. So, for example, the 'o' will not be just a hole in the paper, but actually a 'o'. These kind of fonts have no close circles. However, you should use a 'stencil' font. If the paper is thick enough, no light will pass. If you are able to use a laser cutter, an option is to cut-out the letters from paper. A possible solution is to print the face twice and stack them on top of each other. A drawback of this option is that the ink should be dense enough to be non-transparent. You can print the negative of the letters on the foil. The face of the Word Clock is determined by the letters through which the light indicates the time. Of course, you can build your own frame if you like, but I would stick to the RIBBA frame. The advantage of this is that you start with a frame of which all angles are nicely 90 degrees and the finish of the outside is seamless. That is why I build almost all my Word Clocks using the RIBBA frame of IKEA. Now the inside of the Word Clock is clear, we move on to the outside.įrom experience I know it is important to start your project from a convenient base. I work with the DS3231 RTC, which is quite cheap and a lot of support is available on the internet. The idea of this module is that once you set the correct time, it keeps ticking (until its battery is dead). In my Word Clock, an Real Time Clock module (RTC) keeps track of the time. Of course, the purpose of any clock, besides being pretty, is to display the time. All a terminal adapter does is to enable us to connect our wires to the Arduino using screws. To avoid a lot of soldering (which takes time and is quite a craft), I use a terminal adapter for the Arduino Nano. You can find infinitely many programs on the internet to mess around with, quite fun! This tiny computer is able to control the RGB led strip. The brain of the Word Clock is the Arduino Nano. This works perfectly fine, but takes a lot of time to build! However, in my first version, I made the grid out of thin wooden strips which I glued together. I also tried this, but this did not work out for me. In other Instructables, this grid was made using foam strips that are put together in a grid.
To accomplish this, I used a laser cutter to cut out a grid of wooden board. So, when one led turns on, it should light up one letter.
So, by connecting one wire, you can control all the leds in the strip!īehind every letter on the face of the Word Clock (please see later this step) hides one led of the RGB led strip. The RGB led strip is controlled by one input (still a bit of magic to me). By combining the three colors, (almost) every color can be created. My current version uses a RGB led strip: this is a led strip in which each 'light bulb' consists of a Red, Green and Blue led. Now that I made eight Word Clocks, which I try to improve each time, I think it is time to share my experience!Īn advantage of my experience is that the latest version of my Word Clock is actually quite simple: if you have all the components, you should be able to build it in one day. A few years ago, I started making my first Word Clock, inspired by the nice Instructables available.
