How SPI, QSPI Serial to Peripheral Interface Woks ?
The SPI(Serial to Peripheral Interface) develop by Motorola and later adopted by Microwire of National Semiconductor and other companies. SPI is a hardware / firmware communication protocol or sometimes Engineers called it a “four wire serial bus” communication. The SPI
Burning Bootloader to ATMEGA328-AU with Arduino ISP
This guide I’m going to demonstrate to you how we going burn a Bootload to Arduino 328P-AU Mini Pro using Arduino UNO 328P as a host, base on previous article we manage to bootload the without Arduino ISP a fresh
Burning Bootloader to ATMEGA168P/328P with Arduino ISP
Sometimes you need to burn Bootloader into your ATMEGA Integrated Chip. You can also purchse a chip that comes with preloaded Bootloader or ISP programmer like USBASP, actually any working Arduino can be used also. This tutorial I’m going to
Introduction of RFID System & Wiring the VHF Reader/Writer 13.5Mhz on Arduino

Automatic identification procedures provide information on people, animals, goods, products, transportation’s, the most common form of
Wiring MOSFET to Arduino and Driving Bigger Loads
Each one of Arduino Pins can be used to power devices that use up to 20 mA, this is a very small amount of current to drive, just enough to run an LED. If you try working to drive something
What is OpenELEC? Media Centre
What is OpenELEC? Media center were one of the first projects to think for the Raspberry Pi and they have gone to become so popular. The Raspberry Pi Foundation has invested in their development to mass production, and they been
SSH (Secure Shell) vs VNC (Virtual Network Computing) how it works?
SSH(Secure Shell) is mostly used many system administrators to control or remotely work with the servers across the world. for example a VPS (Virtual Private Server running a website or web application), they need a remote connection because they don’t
Code Libraries
Raspberry Pi Libraries WiringPI is PIN based GPIO access library written in C for the BCM2835 an Arduino like code. WiringPi includes a commandline gpio which can be used to provide instruction to setup the GPIO pins. You can also
How Servo Motor Work? and how to control theme using Arduino
Servo motors mostly use in toy cars, airplanes, robots, industrial machinery, manufacturing, pharmaceutics. The servo circuitry is built-in inside the motor itself and has a positional shaft which usually fitted with a gear. The motor is controlled with an electrical
