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...

Arduino-project 002 – Pulsating LED

A blinking LED is perhaps not the most exciting thing in the world, but if you can get it to pulsate instead it would be a little more interesting. Build the circuit from project 001, but use the code below instead. Here we use a for-loop to gradually increase the...

Arduino-project 001 – Blinking LED

The circuit A very good project to start with if you’re new to Arduino is to get a LED to blink. The first you need to do is connect it physically to the Arduino board. Do this according to the schematics below. Please note that the LED only works in one...

Arduino-projekt 008 – Styr motorer med motor shield

En robot behöver kunna röra sig och för det behöver man motorer. Men motorer kräver mycket ström och det går inte att koppla in dem direkt till ett Arduino-kort. Därför behöver man en motor-drivare av något slag. Den enklaste att använda är Arduino Motor Shield R3....
