Here is another guide from David Johnson-Davies @ technoblogy.com explaining how to program an ATmega328 on a breadboard using the Arduino IDE. The guide is focused on how to use the internal clock of the microcontroller and how to achieve this using the Arduino environment. By default...

David Johnson-Davies @ technoblogy.com build a breadboard friendly power supply to power your Arduino or other low power electronics. The power supply is able to deliver 0V to 5.5V at up to 0.5A and it's powered from two Li-Ion rechargeable batteries. The output can be adjusted using...

DevDuino is a Fully Redesigned and Enhanced Arduino-Compatible Board with Plenty of Must-Have Features. It features a 128x64 OLED display, along with a variety of LED indicators, RTC module, a slot for a micro SD card, and many other convenient features. The project is live on...

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...

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...
