One of the limitations of the small 8 bit microcontrollers like the Atmel ATMega family adopted by the Arduino board, is the reduced number of I/O ports. Among the main advantages of these ...

Community collaboration is a great thing. Take the Arduino PWM library for shift registers. Some folks at the Arduino forum pitched in and helped [Elco] trim off a bunch of clock cycles by using the ...

Shift-out: again? Yes, shift-out registers again, now daisy-chained! But let me write down a short foreword. As probably occurs for most of the subjects, especially those related to the Arduino board, ...

Recent DIY trends show makers increasingly turning to ESP32 microcontrollers and Arduino platforms for smart home projects, replacing costlier or overpowered setups like Raspberry Pi in many cases.
