This Python script interfaces with an Arduino board (I used the Due) equipped with 5 gas sensors, namely MQ8, MQ4, MQ9, MQ7, and MQ135. It reads sensor data from the Arduino via serial communication, ...

Functionality: IR Sensor Detection: The IR sensor is connected to digital pin 7 and is used to detect the presence or absence of an object (e.g., the door). LED Indicator: An LED connected to digital ...

To create a graph based on the received serial data from Arduino Serial Plotter, you need to program Arduino to read a sensor and direct the data to the Serial Port. Here, a standard light-dependent ...

What do you need to build an Arduino Speed Sensor. Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, and it is also very ...

Circuit Diagram Here you can find the circuit diagram for the Bidirectional Counter using Arduino. The circuit diagram below represents how an Arduino, a pair of IR sensors, and the LCD display are ...

Being only ten at the time I was unable to build the thing and, now that I’m 40, I still can’t fathom how to build this DIY CNC plotter out of a DVD player and some Arduino gear.
