Switch LEDS off and on by column #include <Charliplexing.h> void setup() { LedSign::Init(); // initializes the screen } void loop() { for (int x=0; x<14; x++) { for (int y=0; …

This is the first of a new category, just code snippets for you to try. First example is random LEDs on using the LOLShield and an Arduino   Code #include …

I recently bought a nice looking shield for experimenting with, it was based on a Nokia LCD, I believe is used in the Nokia 6100 mobile phones. Its a colour …

This example shows how to connect a joystick to your Arduino. Here is a picture of the joystick I am using, again this was part of the 37 in 1 …

In this example we show how you connect a photoresistor to an Arduino, the value read from the photoresistor corresponds to the amount of light present. The photoresistor is connected …

This is part of a 37-1 sensor kit, this was a multi-colour LED that was in the kit. NOt much documentation but I wired it up as follows I – …

Another simple example is to hook up a speaker to your Arduino and get a bit musical with it. These are fairly low cost and can quite often be salvaged …

In this example we will show a basic example of connecting a DHT11 Temperature and Humidity Sensor to your Arduino. This is a very nice little, low cost sensor which …

Here are some more LED examples for use with the QL200 development board Example 1: #include //We use an xtal crystal, no watchdog, //no low-voltage protection and no code protection. …

In this example we will connect a Piezo buzzer to our arduino and play some basic sounds, this uses the PWM functionality of the Arduino. The Arduino PWM runs at …
