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, ...

This project involves creating a simple door status monitor using an Arduino Uno, an IR sensor, and an LED. The purpose of this project is to detect whether a door is open or closed and display the ...

Arduino Serial Plotter. Serial Plotter is an amazing tool available in Arduino IDE (from v1.6.6) to visualize the “returned” data beyond just seeing numbers spit out onto the traditional serial ...

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 ...

We are going to use this technique to build a our bidirectional visitor counter using arduino and ir sensor. By placing two IR sensors one after another in series as shown in the above image at a ...

This paper presents an implementation of smart, and inexpensive human body temperature detector by using portable electric system based on Arduino UNO, and MLX 90614 IR temperature sensor. The ...

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.
