If you have an RTL-SDR compatible radio there’s an excellent chance you’ve heard of the rtl_433 project, which lets you receive and decode signals from an ever-expanding list of supported devices in the ISM radio bands. It’s an incredibly useful piece of software, but the fact that it requires an external software defined radio and …
Particle Photon is a tiny micro controller, just about the size of an arduino nano. But the photon is designed for easy IoT prototyping, it supports OTA updates to its firmware. So all we have to do is get it connected to the internet and we could do all the programming wireless, the photon uses a …
OLED!! What is an OLED? OLED ( Organic Light Emitting Diodes ) is a flat light emitting technology, made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. OLEDs can be used to make displays and lighting. Because OLEDs emit light they do not require a backlight and …
There are lots of Instructables on how to use SSD1306-based 128×64 OLED displays. Many of these write-ups are very informative but just about all of them look like an unfinished science project. (In fairness, most are directed at getting up and running with the display, not creating a finished product). Here’s a quick and easy way to …
Hearing loss is a common problem for many – especially those who may have attended too many loud concerts in their youth. [mircemk] had recently been for a hearing test, and noticed that the procedure was actually quite straightforward. Armed with this knowledge, he decided to build his own test system and document it for others to …
In the world of hardware hacking, you sometimes spend a ridiculous amount of time debugging a problem, only to find a simple solution that was right in front of you the whole time. [Zack Freedman] got a good dose of this while building the Optigon V2, a modified Epson Moverio wearable display he uses as a …

In this tutorial I am going to show you guys how to make an Arduino or NodeMCU based Weather Station using DHT11 or DHT22 temperature and humidity sensor and display it using an OLED Display. Video In this tutorial I am going to show you guys how to make an Arduino or NodeMCU based Weather …
Older hackers will remember that a crystal set radio receiver was often one of the first projects attempted. Times have changed, but there’s still something magical about gathering invisible signals from the air and listening to the radio on a homemade receiver. [mircemk] has brought the idea right up to date by building an FM radio with …
In this tutorial I will show you how to create animation on small OLED display connected to Arduino Nano. Step 1: Supplies We need following two components for this project Arduino Nano SSD1306 SPI 128×32 display You can also use SSD1306SPI 128×32 display but it will need code adjustments when declaring the display. Step 2: …

There’s something about Reverse Polish Notation (RPN) and the calculators that use it. It calls to mind a time when a calculator was a serious tool, and not just a throwaway toy. Created in the legacy of such calculators by HP and Texas Instruments, [Simon Boak] shows off his SB116, sporting an Arduino Nano under the …

Every now and then you might be interested to input text to your arduino project. You can do it using Serial input but this would require Arduino to be always connected to a computer. In this tutorial I would show you how to implement text input using the small OLED display and 5 key keyboard …
A new project will soon be launching via the Crowd Supply website in the form of the fully programmable, open source, ESP32 macropad, aptly named DeepDeck. The wireless programmable macropad features 16 mechanical buttons in a 4×4 grid together with two RGB rotary encoders, hot swappable keys and more. Connecting to a wide variety of different platforms using Bluetooth, DeepDeck supports Windows, MacOS, …
