Arduino fishtank light control

Here is how the final product looks like:   The required parts are: – an Arduino Uno board; – a LCD shield; – a relay; – two brick buttons; – cables. The case is optional, but here is the 3D model if you want to 3D print it: http://www.thingiverse.com/thing:2008460 We will connect our fishtank’s lamp to a relay, that we will turn on and off at certain times a day.

Javascript Artificial Intelligence Tutorial – For beginners

Here is a simple JavaScript Artificial Intelligence Tutorial for beginners using the reinforced learning method. You need to have basic knowledge on HTML, CSS and JavaScript, as well as programming basics. This tutorial is a starting point for people who want to implement A.I. in their projects. You are free to “steal” ideas and techniques from this 🙂 In this tutorial we will create a car with an A.I. driver, which will drive along a road avoiding obstacles. The avoiding will be made by the A.I. and not by direct programming (like using IF-statements). There are multiple ways to achieve Continue reading
