Probably many of us have a small gadget in the house like hourglass. Unfortunately, it usually serves at most as an ornament because nobody wants to rotate it. I received this type of toy a long time ago and it layed on the shelf for a long time until I automated its rotation with just a few electronic components.
Arduino is a very interesting device through which we can build a lot of unusual electronic designs. The cost of original device such as Arduino Uno is about 25$ and even if we decide to buy Chinese substitute rarely wewi;; be able to find anything with price lower than 5$. For many projects this may be already suitable price, but with all the options offered by Arduino Uno we usually only need what gives us a main component which is microcontroller and it’s price and size is not large.
Led Cube is a relatively interesting gadget that can surprise many guests. This is a toy consisting of RGB LEDs that can be individually programmed to give a very spectacular visual effects. In this article will be shown how to create such toy yourself using mostly 64 RGB LEDs and a microcontroller.
Who does not like flashing toys. Some time ago I created Led Staff a stick with led lights where each LED can be individually programmed using bluetooth creating unlimited number of beutiful patterns. The instruction on how to build it is as follows.
When creating electronic designs often we use the bread board. Nevertheless, we would like that our project would took a more permanent form. In such case we may transfer our project to PCB. Best of all is that everyone can prepare such board at home.
Binary clock is a relatively popular gadget among programmers in many stores you can buy a version of alarm clocks or to wear wrist. However, nothing gives more satisfaction than create such a watch yourself. This post will show you how to build your own binary clock using Ardunio and several electronic components.
