We love the simplicity of Arduino for focused tasks, we love how Raspberry Pi GPIO pins open a doorway to a wide world of peripherals, and we love the software ecosystem of Intel’s x86 instru… ...

The live GPIO pin monitoring library sets up the ESP32 to stream information about what all of the pins are doing in real time to a webserver, which displays the information as a helpful graphic.

Arduino boards can most definitely help with that. These microcontroller boards are designed to send and receive data to and from the components connected to their pins.

Arduino Uno. 4-channel relay module. PIR motion sensor. Steps: 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 ...

It offers 76 GPIO pins, accessible from underneath for easy project expansion. Notably, it operates at 3.3V. Additional pins include a VRTC for RTC battery connection and an OFF pin for powering ...

I always like projects that bring the Raspberry Pi and Arduino together, however gently. It's what the world needs, a bit more harmony. Check out this little one on GPIO programming on a Raspberry Pi ...
