The rotary encoder is a great user input device with a satisfying tactile feedback. A lot of user interfaces are slowly transitioning towards button-less devices, but when in need of a physical system, I always love to use encoders. However if you have ever worked with one, you know they […]

After publishing a review of the STM32 “Blue Pill”; there was only one thing left to do: how to program it with Arduino of course! You will find the complete tutorial by accessing the menu, under Arduino; or simply by clicking on the link below. Enjoy! Access the tutorial
Arduino has been traditionally dominated by Microchip-Atmel chips. The Uno uses a 8 bit AVR, and the newer boards have a 32 bit SAMD21 ARM core. Enters a new alternative, code name “blue pill”; and it’s fantastic! What is the STM32 Blue Pill? The STM32 “Blue Pill” is a development […]
As part of the process of building a VFD (vacuum fluorescent display) filament driver, I use an ATTINY to generate a square wave signal. I program these chips using an Arduino Uno used as a programmer through the “Arduino as ISP” sketch. This process is painfully slow. Every time you […]
We continue to enrich the website with new content and today I am pleased to share with you a new tutorial on the Microchip 47C16 2kb I2C ram (and its 47L16 low power counterpart). It’s in my opinion one of the best chip to start with an external serial […]
The most observant of you guys might have noticed that there’s a new tutorial available from the menu: how to interface a Si7021 humidity and temperature sensor with Arduino. I went all in with this one, going deep enough to create my own library which supports all features of this […]
What’s new in China? New maker products roundup June 2017 Here are new maker products recently released which are worth looking at: Air quality sensors Reland Tech has some new air sensors: a PM2.5 pollution sensor for US$7.00 a CO2 sensor for US$22.90 a CO (Carbon Monoxide) sensor for US$18.00 […]
The Arduino Mega is a great board. You can often get a project that typically requires multiplexing or shift registers running with a single Mega board because it contains so many GPIOs. The only problem I have with it is its massive size. Enters Robotdyn shrunk versions, and for about […]
A new how to guide has appeared on the main menu: how to manipulate whole ports. If you are mildly experienced with Arduino, this will further your knowledge and bring you closer to the underlying micro-controller hardware. It’s a short read that could be useful in your next project so take […]
