In this example we connect a photoresistor to an Arduino, the value read from the photoresistor corresponds to the amount of light present. The photoresistor is connected to analog pin 0 in this example. A photoresistor (or light-dependent resistor, LDR, or photo-conductive cell) is a …

An RGB led is a combination of a Red, Green and Blue LED’s in one package, they can be common cathode or common anode types In the example I used an RGB LED breakout. The LED was wired up as …

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 requires only a pull up resistor to VDD. This can …

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. A piezoelectric element may be driven by an oscillating electronic circuit or other audio signal …

The ability to flash an LED is the most basic ‘hello world’ type of program you can write and run on your arduino. Most Arduino’s have an LED attached to D13, rather than take the easy option we will attach …
