Project 1.1.2: CAR TRAVIGATOR BLINKING
| Description | This project shows how to make an LED turn on and off repeatedly using an Arduino Uno. It introduces the basic idea of blinking lights with time control. |
|---|---|
| Use case | Blinking LEDs can be used in simple signal systems, such as car indicators, warning lights, and smart lighting systems. |

Building the circuit
Things Needed:
- Arduino Uno = 1
- Arduino USB cable = 1
- Red LED = 1
- Red jumper wires = 1
- Blue jumper wires = 1
- 220Ω Resistor
Mounting the component on the breadboard
Step 1: Place the LED on the breadboard. The longer leg is the positive pin, while the shorter leg is the negative pin.
.
NB: Make sure you identify where the positive pin (+) and the negative pin (-) is connected to on the breadboard. The longer pin of the LED is the positive pin and the shorter one, the negative PIN.
WIRING THE CIRCUIT
Things Needed:
- Red male-male-to-male jumper wires = 1
- Blue male-to-male jumper wires = 1
Step 2: Connect the positive leg of the LED to pin 6 on the Arduino through a 220Ω resistor.
Step 3: Connect the LED's negative leg to GND on the Arduino using a jumper wire.
.
make sure you connect the arduino usb blue cable to the Arduino board.
PROGRAMMING
Step 1: Open your Arduino IDE. See how to set up here: Getting Started.
Step 2: Type pinMode (6, OUTPUT); in the void Setup() function.
.
Step 3: Type the following codes in the void loop function as shown below;
digitalWrite (6, HIGH);
delay (1000);
digitalWrite (6, LOW);
delay (1000);
.
Step 4: Save your code. See the Getting Started section
Step 5: Select the arduino board and port See the Getting Started section:Selecting Arduino Board Type and Uploading your code.
Step 6: Upload your code. See the Getting Started section:Selecting Arduino Board Type and Uploading your code
