Watch this video, follow all the steps!! This is code: pinMode(8, OUTPUT); digitalWrite(8, LOW); mlx.begin(); //you start the serial connection with the senor delay(500); //wait for 0.5 second digitalWrite(8, HIGH); //When 8 is high it will connect the sensor to the Arduino SCL pin delay (500); //wait for another 0.5 […]
Please don't try this at home and always remember that Arduino UNO Supply voltage varies between 5V and 12V
DHT temperature and humidity sensors, are very basic and slow, but are great for hobbyists who want to do some basic data logging. Each DHT is made of two parts: Capacitive Humidity Sensor and Thermistor. There is also a very basic chip inside that does some analog to digital conversion […]
In this tutorial, we will show you how to build a low cost thermometer, using Arduino & DS18B20 waterproof version (Digital Temperature Sensor) Step 1: Items you need to have Arduino UNO (or other Arduino Models) DS18B20 Waterproof Resistor 4.7KOhm (Preferably 1/2Watt). You can check the Watt availability for 4.7KOhm […]

WiFi connections are sometimes a must in your project. It really gives it the IoT identity and power to send/receive messages/commands from anywhere using only an internet connection. Although you might think it’s hard to add this option to your project, a simple google search can prove the opposite. Before […]
