In this tutorial we interface XBee module with Raspberry Pi which will act as a receiver and make it communicate wirelessly with another XBee module (XBee explorer board) which is serially connected ...

In this tutorial we are going to do Raspberry Pi 7 segment display interfacing. Seven Segment displays are the cheapest for a display unit. A couple of these segments stacked together could be used to ...

In this project, we would be interfacing dot-matrix LED with Raspberry Pi. We would be interfacing an 8×8 and a 5×7 LED.

Raspberry Pi LED and switch circuit board This is a small board that can be fitted on top of the Raspberry Pi GPIO pins. It has the following features; 3 individual LEDs 1 RGB LED 2 slide switches 4 ...

The black wire is connected to any Ground pin on the Raspberry Pi and to the Ground pin (Cathode) of our LED and to the other side of our momentary switch. Here is a quick diagram that shows the ...

The ‘time circuits’ shown on-screen in Back to the Future actually weren’t very complex; the times were just cutouts with lights and gels; no real electronics wizardry necessary.

With Opto-pi, there is not an electrical connection between the Raspberry Pi and connected loads (motors, relay coils, etc.) or input signals. Opto-pi uses light to isolate the 8 digital GPIO pins.

The ' Raspberry Pi Pico 2 ', which was released on August 9, 2024, is equipped with the ' RP2350 ', a proprietary microcontroller equipped with an Arm core and a RISC-V core. The RISC-V core was ...
