Interfacing PIC18F4550 with DS3231 RTC The DS3231 is a low cost , extremely accurate real time clock with a built-in crystal oscillator. The characteristics of the DS3231 make it one of the best choices for real time clock chips. This project shows how to build is simple real time clock and calendar (RTCC) using PIC18F4550 microcontroller and DS3231. The DS3231 uses I2C protocol to interface with the master ...

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 ...

A time controlled switch is an automatic timer switch that turns an appliance ‘on’ for the desired time duration. After the preset time duration, the timer automatically switches off, disconnecting the appliance from the power supply. The time duration for which the appliance should be ‘on’ can be set from 1 to 99 minutes. This switch obviates the need to continuously monitor the appliance—an advantage over ...

(Some knowledge about RC-5 protocol is required) This project shows how to build a remote controlled real time clock with TFT display using PIC18F4550 microcontroller.
