Dancing external LEDs circuit setup
Let's write a program to dance LEDs in both directions like we did in the previous chapter. For this exercise, you will need:
- Seven LEDs: We are using seven LEDs to create a dancing pattern
- Male-to-male jumper wires: We need jumper wires to connect BeagleBone and components through a breadboard
- Seven resistor 400Ω–1kΩ: A resistor is needed to limit current flowing through an LED to protect it.
- Half size breadboard: A breadboard is needed to create a solderless circuit.
Power off the board and disconnect the power and USB cable. Then attach components to BeagleBone as shown in the previous diagram.
