In the previous tutorial I showed you how to build a weather station using only the DHT11 sensor and I said the readings from this sensor is fairly accurate. In this tutorial, I will be using the DHT11 to measure only the humidity and BMP180 to measure pressure and temperature. That’s...

Tiny 32-bit Dev Board. 14.9mm², Breadboard, 0.95g, 3-20V input, I²C, 8 PWM, Serial, 6 ADC, Prog LED. There is a new board in the ecosystem which claims to be the world’s smallest 32-bit Arduino board. The name of it Atom X1 and measures 14.9×14.9 mm. Atom X1 specifications:...

Even if you have years working with electronics, you will still find some simple hacks that you never thought about before. Personally and to save money, when I was a student with a very limited budget I knew that my Arduino UNO can work as a USB/TTL(serial) converter. I used to remove...

Welcome to another Arduino Tutorial! Today we are going to learn how to use Bluetooth to exchange data between two Arduino boards! As a demonstration project, we are going to build a simple weather station. There is a lot to cover so let’s get started! Arduino Two-Way Bluetooth...

Using a display to view the temperature and humidity of your environment can be possible using the DHT11 or DHT22 sensor with the easy to use Arduino microcontroller platform and that’s the goal of this project. For this project, we will be using the 16×2 LCD display module to...

In this blog post you're going to learn how to decode (parse a JSON string) and encode (generate a JSON string) with the ArduinoJson library using the Arduino with the Ethernet shield. This guide also works with the ESP8266 and ESP32 Wi-Fi modules with small changes. Decoding and...

WINXI - arduino ZERO Pro M0 compatible stick, RGB led, Micro SD, AtSamD21E18. Arduino zero pro compatible board with USB programming suitable for experienced users. WINXI - Arduino ZERO M0 Stick -...

In this tutorial we’re going to show you how you can turn a 12V lamp on and off by sending SMS to your Arduino with the text “ON” and "OFF", respectively. You can also request the current lamp state by sending an SMS with the text “STATE”, the Arduino should reply back with...
