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:

 I2C Communication: This post rewind the I2C Hardware overview, I2C Pullup resistor value calculation, and LT Spice simulation. Hardware Overview: The I2C bus is a very popular and simple bus used for communication between a master or multiple masters and single or multiple slave devices.  This communication only uses two-wire SDA and SCL. Which is a serial data line and serial clock line.  Both SCL and SDA lines are open-drain or open-collector configurations. This means it needs an external pullup resistor is completely taking control of generating the logic high signal. I2C uses an 8-bit data structure which is a common data format for most Microcontroller and Microprocessor In the 8 bit communication, 7 bits are address bits and the last bit represents the Read/Write operation (1=Read Write =0) I2C Protocol is address-based, meaning that all the slave IC must have a unique address, this address is configured through hardware pins to logic "1" or "0". Some slaves...

PIC12F675 LED Blinking Code This post provides the code to make an LED blink using PIC12F675 microcontroller. This code is written in C language using MPLAB X IDE with XC8 compiler. This code is intended to be the first step in learning how to use PIC12F675 microcontroller in your projects. Code: // PIC12F675 Configuration Bit Settings // 'C' source line config statements #include <xc.h> /*define clock freq*/ #ifndef _XTAL_FREQ   #define _XTAL_FREQ 4000000  // 4MHZ crystal #endif // #pragma config statements should precede project file includes. // Use project enums instead of #define for ON and OFF. // CONFIG #pragma config FOSC = INTRCIO   // Oscillator Selection bits (INTOSC oscillator: I/O function on GP4/OSC2/CLKOUT pin, I/O function on GP5/OSC1/CLKIN) #pragma config WDTE = OFF       // Watchdog Timer Enable bit (WDT disabled) #pragma config PWRTE = OFF      // Power-Up Timer Enable bit (PWRT disabl...
