motion detectors, and robotics. The Arduino board allows users to program and control the IR sensor using a simple set of instructions. With the ability to sense infrared radiation, the Arduino IR sensor can be used to detect the presence of objects, measure temperature, and even control...
In this article, we will learn how to similar speed sensor using Arduino and IR sensor. By setting up the two IR sensors at a fixed distance from each other, we can track the time it takes for the object to travel between them. With the recorded time and the known distance between ...
Here are the different features of the Arduino IoT cloud Data Monitoring: This helps you learn ways to monitor the sensor values of the Arduino easily via a dashboard. Scheduler: This helps in scheduling jobs to go either on or off for some specific time period. This could be hours, minut...
Arduino code is written in C++. The second step is to connect your Arduino to a computer via a USB cable and launch the Arduino IDE. Head to theToolsmenu and hover over ‘Port‘ to see if your Arduino was detected. If not, follow the link in the paragraph above for more information....
If you have any questions about how to set up the DHT11 humidity and temperature sensor on your Arduino, just leave a comment below and I will try to answer it… And if you like our tutorials, please subscribe! Also, feel free to share this if you know anyone else that might find it...
Arduino Uno MQ-3 Alcohol Sensor – Connection Diagram Now that we knowhow the MQ-3 alcohol sensor works, we can connect all necessary wires to an Arduino Uno and see how it functions. We'll start with the analog component and then go on to the digital part, which is pretty simple. ...
In this Arduino Tutorial you will learn how to use the HC-SR04 Ultrasonic sensor. It can measure distance from 2 cm to 4 meters with a ranging accuracy of 3mm. Arduino and MPU6050 Accelerometer and Gyroscope Tutorial In this tutorial we will learn how to use the MPU6050 Accelerometer and Gy...
In this tutorial I will show you how I build an Arduino RC Airplane. Also, I will show you how to control it using a custom build Arduino RC transmitter...
How to Connect the Microphone Circuit to an Arduino The complete circuit is shown below: The output signal, again, comes from pin 5 of the LM386 IC. The positive terminal (+) goes into an analog terminal of the Arduino; we will connect it, in our case, to A0 of the analog terminal...
if(!tb.connect(THINGSBOARD_SERVER, TOKEN)) { Serial.println("Failed to connect"); return; } } MQ135.update();// Update data, the arduino will be read the voltage on the analog pin MQ135.setA(110.47); MQ135.setB(-2.862); CO2 = MQ135.readSensor(); ...
