Use Arduino to handle sensor input and relay control. Pi runs a Python Flask server with a simple UI to toggle GPIO pins via serial commands sent to the Arduino. Use cron jobs on Linux to schedule ...

This set of microcontroller boards start around $25 and come in the smallest footprint made by Arduino, allowing you to build compact and portable devices that are more difficult to make with an Uno.

Aside from the Arduino UNO microcontroller, LDR, and the bulb itself, the hardware for this setup is pretty minimal: a relay for the bulb, a resistor for the LDR, and some wires to connect ...

So far in this series, from prototype to production, we have examined a few fundamental requirements for an industrial IoT controller utilizing Arduino hardware and even how a developer can use Python ...

Using the Arduino microcontroller, we will explore some of the essential and useful electronic sensors (light, sound, motion, sonar, infrared, angle bending), powerful actuators (relays, motors, ...

Originally developed in Italy in 2005 as a tool for students building interactive design projects, the Arduino is a microcontroller-based prototyping board - but one that pretty much removes the ...

The Arduino Due has a 32-bit ARM core (the Uno is 8-bit), an 84 Mhz CPU clock, 96 KB of SRAM, and more USB ports than the Uno. In short, it's a much more powerful microcontroller that can handle a ...

Controllino is a professional PLC for private and industrial use, build around Atmel’s ATmega328 and the ATmega2560 microcontrollers, ready to run with your ARDUINO projects. learn more from the ...

He builds a simple dead bug Arduino (which he calls an Audioino) using a handful of resistors, a pair of caps, an LED, a reset switch, and most importantly – an audio jack.

Adding USB functionality to your Arduino projects used to be a pain, but thankfully, the V-USB project came along and gave your ATMEGA328 the ability to control the USB lines directly and mimic sim… ...
