technoblogy.com published another in detail project. This time is an eight-character alphanumeric LED display with an I2C interface. This is an eight-character alphanumeric LED display with an I2C interface. It's based on a low-cost HT16K33 display-driver chip, and supports four...

The latest offering from Teensy, Teensy 4.0 is the fastest microcontroller available today which is powered by ARM Cortex-M7 processor at 600MHz, with an NXP iMXRT1062 chip. Teensy 4.0 has the same dimensions (35 x 18 mm) of Teensy 3.2 and maintains compatibility with most of the pin...

Thanks to their tiny size and improved capabilities, the ATtiny-0-Series of microcontrollers have been a delight for designers and DIYers looking for a microcontroller with the ease of use associated with the Arduino boards, but with a way smaller form factor associated with ATtiny...

If you have ever considered the option of using encryption in your design, then you should be able to perform a side-channel attack as well as understand the consequences of such an attack on your product. While oscilloscopes and differential probes can be helpful in traditional power...

tinyPulsePPG, an ATTiny85 Pulse Oximeter with Photoplethysmogram (PPG) display by Jeff Magee: This project implemented on an ATTiny85 displays a moving Photoplethysmogram together with pulse rate and estimates of SpO2 – blood oxygen percentage. It uses an SSD1306 128×32 OLED display...

644 Narrow and 1284 Narrow are the simplest and perfect upgrade option for all your small footprint Arduino projects. The Narrow board gives you 2 to 8 times more flash and RAM resources as compared to a Uno/Nano, plus total compatibility. A large amount of effective Flash and...

This is a USB-stick sized UPDI programmer, for programming Microchip's new 0-series and 1-series ATtiny chips from the Arduino IDE. It's based on an ATmega328P, and is essentially an Arduino Uno on a USB stick, so you also could use it as a mini-sized Arduino Uno. by David...

David Johnson-Davies published another great mini project. It's a Timer based on ATtiny402 and was build to demonstrate the low power sleep mode of the microcontroller. This article describes how to use the new 0-series and 1-series ATtiny microcontrollers in low-power projects, taking...
