Often you want to iterate over a series of pins and do something to each one. For instance, this example blinks 6 LEDs attached to the Arduino by using a for() loop to cycle back and forth through ...

The core of the project is an optical communications system where an LED transmits data, and a photoresistor receives it. This forms the basis for several additional mini-projects where sensor data is ...

To link a standard 16×2 LCD directly with the microcontroller, for instance Arduino, you would need atleast 6 I/O pins to talk to the LCD. However, if you use an LCD module with I2C interface, you ...
