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. To work with the Sensor, we must first power it. We...
In this article, well look at a basic use case involving data collection from a temperature sensor connected to an Arduino Uno, then sent to InfluxDB via the native UDP plugin. Learn the InfluxDB line protocol, how to monitor Arduino Uno, its hardwar

Arduino based Line Follower Robot A Line Follower Robot (LFR) is one of the most popular Arduino robotics projects that teaches core concepts of automation and sensor integration. This step-by-step guide will show you how to build a professional-grade line follower robot using Arduino UNO, with...
How to Connect a Serial LCD to an Arduino UNO: In this instructable I will show you how I connected a serial LCD 16X2 to an Arduino UNO. There are lots of instructables and tutorials showing you how to connect a regular LCD to an Arduino but not many sho
The circuit diagram to connect the Arduino with the BMP280 sensor and the LCD is shown below. If you are completely new to Arduino and LCD, then you can check this Arduino LCD tutorial to understand how to use Arduino with LCD displays. The VCC and GND pins of the sensor are connected...
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(); ...
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...
this tutorial I made two basic examples explaining the how to connect the HC-12 module and make a basic communication between two Arduinos and an additional example where using an accelerometer sensor at the first Arduino I wirelessly control the position of the stepper at the second Arduino....
ArduinoUNO US1881 Hall Effect sensor 10kΩResistor 4.7nFCapacitor Breadboardand Jumper Wires Schematic Diagram Connect the VDD pin of the US1881 Hall effect sensor to 5V on the Arduino and the GND pin to GND. This sensor uses anopen-drain output, which means that you need apull-up resistor...
