While a Raspberry Pi is a full-fledged computer that can do more complex things than an Arduino microcontroller, it's not the best choice for every project.

PWM pins are generally used in controlling output devices in Arduino projects. To send a PWM value to a PWM-capable pin like the Mega's D9, the easiest and most common way is by using the ...

Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor techniques. Perfect for compact projects, keyboards, or when using small ...

Literally, ATtiny85 is a scaled-down version of the Atmega microcontroller on Arduino boards with just a few I/Os (five usable pins) that can listen to or talk to most sensors and transducers.

To ensure that the head unit buttons still work in conjunction with the steering wheel buttons, the Arduino would have to keep the pins as inputs until a steering wheel button was pushed, the pin ...

[Ralph] wasn’t satisfied with the required 5 control pins to drive his nrf24l01+ transceiver module, so he used this circuit needing just 3 pin using an ATtiny85. One of the key components wa… ...

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.
