USING TIMERS IN PIC18F452 MICROCONTROLLER:Timers and counters are important as timers can tell the time and count. Counting and timing allows for controlling the brightness of LEDs, controlling the angle of servo shafts and PWM signal generation etc.  All microcontrollers have clocks in them or they use the one that resides outside of a microcontroller. Microcontroller needs clock so our programs can be exe ...

555 TIMER Timers, as the name specified, are the electronics circuits used for measuring time intervals. In this article we will cover about 555 timer. This integrated circuit can be used in variety of ways from which the basic one is to produce accurate and stable delays in electronic circuits. It is available in 8 pin DIP and 14 pin DIP. 555 timers are very popular in electronics projects.  Some they serv ...

The last interfacing of the PIC16F887 microcontroller and DS3231 RTC is the building of a simple real time clock and calendar with two buttons for setting time and date. Project link is the one below: Interfacing DS3231 with PIC16F887 microcontroller In this topic I'm going to add 2 alarms and temperature monitor to the previous project since the DS3231 has 2 alarm functions and temperature sensor with an a ...

The NEC protocol uses pulse distance encoding of the bits. Each pulse is a 562.5µs long with carrier frequency of 38KHz. Logic bits are transmitted as follows: Logic 0: 562.5µs pulse burst followed by a 562.5µs space, with a total transmit time of 1125µs (562.5 x 2). Logic 1: a 562.5µs pulse burst followed by a 1687.5µs (562.5 x 3) space, with a total transmit time of 2250µs (562.5 x 4). The complete extend ...
