[Eduardo Luis] figured out how to implement some of this type office magic using very inexpensive components. Specifically, he can press one button to scan a document and send it to an email address.

How to build your own digital assistant with a Raspberry Pi and Google Assistant. All you need is a speaker and a microphone and Google will do the rest!

For added strength use a hot-glue gun to keep the wires on the contacts. Attach the positive battery terminal to the 3V3 GPIO pin and the GND of the battery terminal to the GND of your Raspberry Pi.

I finally succumbed to their call when I realized the lidar serial interface was a perfect match to a Raspberry Pi’s since both work at 3V3 levels. This would eliminate the USB interface.

Raspberry Pi GPIO Control The first step is to physically set up the Raspberry Pi by connecting it to an LED and a push button.

Raspberry Pi Imager makes installing an OS onto a Raspberry Pi a lot simpler by automating the download and installation. Here's how to use it.

There are multiple ways to do this with the Raspberry Pi’s GPIO Python library, but we settled on the “add_event_detect” method, which can take a callback as an argument.
