Arduino-project 003 – Toggling LED

This project shows the basics of how to get your Arduino to react to external events. In this case we use a push button to toggle a LED on and off. The circuit is similar to that for projekct 001, but we’ve added a push button. The circuit Just as in...

Arduino-project 004 – Dimmer

In project 003 we saw how you read external digital events and values, i.e. whether something is active or not. In this project we will learn how to read analog values, meaning values that can be almost anything, not just one or zero. This can for example be the water...

Arduino-project 007 – Multitasking

For simple projects it’s no problem to do only one thing at a time and waiting until it is done before doing the next thing, but for more advanced projects you sometimes need to do several things at the same time, so called multitasking. You may for example want...

Arduino-project 006 – Display text on a LCD

Sometimes you want to give more information to the user of your devices than what can be conveyed with a couple of LEDs. For that an alphanumeric LCD is a very convenient solution. These displayes can show text and very simple graphics. There are many different...

Arduino-projekt 005 – Controlling a servo motor

Controlling the position of a servo is very similar to controlling the intensity of a LED.The circuit is therefore very similar to the one used in project 004. Just like in that project the total resistance of the potentiometer is not important as long as it is...
