I have been a school teacher for most of my adult life, and like most students, I look forward to the long summer break that awaits us each year. This year as one of my classes learned the basics of LED control with Arduino and then graduated on to displaying simple messages with 4-digit 7-segment

This is a version 2.0 of one of my first forays into Arduino and DIY MIDI programming. I’ve developed my skills in prototyping and design so I thought it would be a good demonstration of process and progression. With a more informed design process I recycled the buttons from my first attempt and set off

The adoption of Wearables has been on the rise especially with the advent of smartwatches and smart glasses, and a growing interest in augmented and the virtual reality space. Most watches are beginning to have some level of smartness and the everyday smartwatch is becoming cheaper. For example, in the last five months, I have

Well most of time i get troubled when i need Arduino in some projects where i need few I/O pinsWell thanks to Arduino-Tiny platformArduino program can be burned into the Avr-tiny Series like Attiny 85/45 Arduino-Tiny is an open source set of ATtiny “cores” for the Arduino platform. It provides a core that enables Arduino

I’m using the tiny and inexpensive Nordic Semiconductor nRF24L01+ transceiver (see “Tutorial: Nordic Semiconductor nRF24L01+ with the Freescale FRDM-K64F Board“) in many projects: it costs less than $3 and allows me to communicate with a proprietary 2.4GHz protocol in a low power way (see “IoT: FreeRTOS Down to the Micro Amps“). I have that transceiver
