If you do not know about LED and ultrasonic sensor (pinout, how it works, how to program ..), learn about them in the following tutorials: -Arduino-LED tutorial ...

Now lets see if the hardware is connected right by uploading the code: #include <Adafruit_NeoPixel.h> #define PIN 2 // Here is where the LED is connected to the Arduino UNO #define NUMPIXELS 10 // ...

The one cool thing about this module is that it has two onboard LEDs built-in ... value where the IR sensor is connected and the second one holds the value where the LED is connected int IRSensor = 9; ...

To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a servo. As the servo rotates, the returns from the ultrasonic sensor are plotted on a screen ...

The UNO is one of the most popular boards in Arduino family and a great choice for beginners. Ultrasonic Sensor: These are the sensor that use ultrasonic waves to detect objects or to measure the ...

To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a servo. As the servo rotates, the returns from the ultrasonic sensor are plotted on a screen ...

The system incorporates an Arduino microcontroller and ultrasonic ... The sensor relays the collected data to the microcontroller, which then determines the appropriate movement and direction for the ...
