  Exploring USB Device Detection with Arduino and USB Host Shield USB (Universal Serial Bus) is a ubiquitous interface for connecting peripherals to computers and other devices. Arduino, with its versatility and expandability, can be used to interface with USB devices using a USB Host Shield. In this article, we'll explore how to detect and identify USB devices connected to an Arduino using a USB Host Shield. Hardware Used: Hardware Description Arduino Board Any compatible Arduino board with sufficient GPIO pins and USB Host Shield library support. USB Host Shield A shield specifically designed for USB host functionality, compatible with the selected Arduino board. USB Devices Various USB peripherals like mass storage devices, input devices (keyboard, mouse), communication devices, etc. Serial Monitor A computer running Arduino IDE or any other serial terminal software for monitoring the Arduino's serial output. Power Supply Depending on the connected USB devices and Arduino bo...

555 Timer Astable mode, Lt spice simulation, and real-time testing  We know 555 timer has three operating modes called Astable mode, Monostable mode, and Bistable mode. Astable Mode : In Astable mode, 555 IC will act as an oscillator that generates a square wave  continuously .  The frequency of the wave can be adjusted by changing the values of two resistors and a capacitor connected to the chip.   LTspice circuit: Formulas: Calculations: Ton = 0.693(1k+100k)22uF =1.539ms Toff =0.693*100k*22uF =1.524ms T = Ton + Toff  = 0.693(1K+2*100k)22ufF=3.064ms  Frequency  = 1/T = 1.44/(1k+2*100k)22uF = 1/3.06ms =0.3263Hz Duty = 50.2% Simulation Results: Click here to download the Astable mode LTspice circuit Testing:
