Switch debouncer using SR Latch

We use switch in our day to day life to switch ON/OFF a bulb or a fan or any electrical devices. But when we use switches in digital circuits, we observe a phenomenon called bouncing. This occurs because, when we turn the switch, the mechanical parts vibrate. i.e It toggles between ON and OFF state for some time until the mechanical contact attain equilibrium. this vibrations are minute and are not at all noticeable in electrical circuit. where as in digital circuits, these vibrations create pulses. which are detected by circuits which results in an error. In the above circuit, there is a switch connected to VCC. You can toggle it between terminal 'a' and terminal 'b'. which as a voltage drop of 'Va' and 'Vb' respectively. In digital circuits if you can observe, it takes a finite amount of time to toggle between terminal 'a' and 'b'. which might approximately take 15ns. Now let us consider the terminal is at 'a'. we

PIC 18F452 Programming: LED blinking using assembly

Here is the basic program you need to start off with when you learn to use a microcontroller. We are using the microchip family PIC microcontroller. Which stands for Peripheral Interface Controller, PIC 18F452 is a 40 pin 8-bit microcontroller with 32 KBytes flash, 1536 Bytes of RAM and 256 Bytes EEPROM. It also boasts 4 timers, and three external interrupt pins. Coming to our first program, We will be using MPLAB for Building this project. Create a new project and select MPASM Suite for compiling. After writing the program, Dont forget to add the linker file and the source file in the source window. The linker file for the PIC 18F452 can be found in the C:\Program Files\Microchip\MPASM Suite\LKR. search for 18f452. In this program, the Bit RB0, toggles continuously with some delay. Connect an LED to The RB0 Pin, i.e Pin 33.connect a 330E resistor in series with the LED. PROGRAM #INCLUDE p18f452.INC; CONFIG WDT=OFF; disabling the watchdog timer ORG 0; Specifing the st
