Taking advantage of the OS

Since the BeagleBone is running a full GNU/Linux operating system, there are plenty of great tools available for us to take advantage of. Let's look at a couple of the advantages an OS gives you.

Every time you click on Run in Cloud9, it launches the program as a new process, so you can easily run many different programs simultaneously. Let's add a second transistor/LED circuit, this time using GPIO3_19 on P9.27.

For this, you will need:

  • Breadboard
  • 2x 5 mm LED
  • 2x 4.7 kΩ resistor
  • 2x 68 Ω resistor
  • 2x 2N3904 NPN transistor
  • Jumper wires

Wire it up on your breadboard as shown here:
