Learn to interface SD card module with Raspberry Pi Pico using SPI. Complete wiring guide, Arduino code, FAT32 setup, file operations & troubleshooting included.

Raspberry Pi 4 Model B is a latest product from Raspberry Pi Foundation with an updated 64-bit quad core processor running at 1.4GHz with built-in metal heatsink, dual-band 2.4GHz and 5GHz wireless LAN, two USB 3 ports, faster (300 mbps) Ethernet, and PoE capability via a separate PoE HAT.

Learn how to set a static IP address on your Raspberry Pi using NetworkManager and nmcli.This tutorial covers step-by-step methods for both terminal and desktop GUI, ensuring reliable network access for SSH, web servers, and IoT projects.

First we'll setup the Raspberry Pi, to do this you'll need to have Raspbian installed. You can buy a Pi with Raspbian pre-installed or you can use a 2GB or larger SD card that you already have.

Raspberry Pi Pico is the first microcontroller from the manufacturers of Raspberry Pi, based on the Raspberry Pi’s RP2040 microcontroller chip and working on ARM’s Dual-core cortex M0+ architecture.

n this tutorial, we will Control a 16x2 LCD Display using Raspberry Pi. We will connect the LCD to GPIO (General Purpose Input Output) pins of PI to display characters on it. We will write a program in PYTHON to send the appropriate commands to the LCD through GPIO and display the needed characters on its screen.

In this DIY project we make a Digital clock by multiplexing four- 7 segment displays using Arduino UNO and displaying the time in HH:MM format. This tutorial covers all the DIY instructions, circuit diagram and required code.

Learn how to control the speed of DC motor using Rasberry pi 2 board. There are 40 GPIO output pins in Raspberry Pi 2. But out of 40, only 26 GPIO pins (GPIO2 to GPIO27) can be programmed. Some of these pins perform some special functions. With special GPIO put aside, we have 17 GPIO remaining.

Anyone who’s shivered in the dark at a scary movie or laughed at the unintentional cheese-ball of a bad sci-fi (paging Ed Wood) knows the eerie sounds of the theremin. In the classic theremin design, two antennas control pitch and volume, and you play the instrument by moving your hands near the antennas without touching them.
