This guide will walk you through the process of setting up MQTT communication between an ESP32 microcontroller and a Raspberry Pi. The ESP32 will send button signals to the Raspberry Pi, which will ...

Tip: to find the right pin number, hold your Raspberry Pi in a way that the GPIO pins sit in the upper-right corner. The top-left pin is pin 1, and to the right of it is pin 2. Below pin 1 is pin 3, ...

Raspberry Pi pin layout (diagram) Here’s what the Raspberry Pi pin layout looks like: As you can see from the above diagram, the pin numbering starts from 1 and goes up to 40.

Screw terminals provide a more secure way of connecting wires to products that may be exposed to vibrations and shocks, and in the past, we’ve seen Pi-oT MKR module enclosure that routes Raspberry Pi ...

You can program the Raspberry Pi’s GPIO pins with Thonny, which is the default Python editor that comes with the Raspberry Pi OS. The following code sets pin 7 (GPIO 4) as an output pin and pin 8 ...

[Zaion] grabbed an ATX power supply to source the 5V the Raspberry Pi needs to run. The common problem when it comes to RPi supplies is a shortfall in how much current a USB wall adapter can source… ...
