Materials
- Arduino Uno (With Software on a Computer or a Laptop)
- Breadboard
- 3 – LEDs (One Red, One Yellow, One Green)
- 3 – 330 Ohm Resistor
- Jumper Wires
Procedure
- Place one wire at the negative rail and on the Ground Pin on the Arduino.
- Place one wire at A5 and on Digital Pin 13 on the Arduino.
- Connect an LED from E5 (anode) to E7 (cathode).
- Connect a 330 ohm resistor from A7 to the negative rail.
- Place one wire at A13 and on Digital Pin 12 on the Arduino.
- Connect an LED from E13 (anode) to E15 (cathode).
- Connect a 330 ohm resistor from A15 to the negative rail.
- Place one wire at A21 and on Digital Pin 13 on the Arduino.
- Connect an LED from E19 (anode) to E21 (cathode).
- Connect a 330 ohm resistor from A21 to the negative rail.
- Connect the power cord to the Arduino and upload the code.
** Be sure to remember POWER RAILS CONNECT VERTICALLY and THE MIDDLE SECTIONS (A-E or F-J) ARE CONNECTED HORIZONTALLY**
