Example Arduino Uno R3 Projects with MaxBotix Sensors
Using MaxBotix sensors in Arduino Uno R3 projects can lead to exciting and practical applications. Below are two detailed examples that you can replicate:
Project 1: Distance Measurement System
This project will help you measure distances accurately using MaxBotix sensors and Arduino Uno R3.
Components Needed:
- Arduino Uno R3
- MaxBotix Ultrasonic Sensor (e.g., MB1010)
- Breadboard and jumper wires
- USB cable for Arduino
- Computer with Arduino IDE installed
Assembly Instructions:
- Connect the V+ pin of the MaxBotix sensor to the 5V pin on the Arduino Uno.
- Connect the GND pin of the sensor to the GND pin on the Arduino Uno.
- Connect the AN (analog) pin of the sensor to an analog input pin on the Arduino Uno (e.g., A0).
Code Example:
int sensorPin = A0; // Analog input pin for the sensor
int sensorValue = 0; // Variable to store the sensor value
void setup() {
Serial.begin(9600); // Initialize serial communication
}
void loop() {
sensorValue = analogRead(sensorPin); // Read the sensor value
float distance = sensorValue * 0.125; // Convert the value to distance
Serial.print("Distance: ");
Serial.print(distance);
Serial.println(" cm");
delay(500); // Wait for 500 milliseconds
}
This code reads the sensor value and converts it to distance in centimeters. The results are displayed on the serial monitor.
Project 2: Obstacle Detection for Robotics
This project helps in creating an obstacle detection system for a robotic application using MaxBotix sensors and Arduino Uno R3.
