Ethernet Relay board

LAN interface with 4 relays, 8 programmable  I/Os and 4 analog inputs, IoT-ready. How many times have you read or heard about the Internet of things (Iot)? The Internet of things is an expression that is becoming more and more popular lately; it represents the expansion of the Internet into the world of objects and physical locations. Thanks to this technology, many objects that used to be exclusively passi ...

NEC Remote control decoder with PIC16F84A

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 ...

RC5 IR Remote Control Decoder with PIC12F1822 Microcontroller

This topic shows an easy and effective way for decoding IR (Infra-Red) remote controls that use Philips RC-5 communication protocol, but first we've to understand how the RC5 protocol works. This Wikipedia links has good infos about the RC5 protocol. The RC-5 protocol was developed by Philips in the late 1980s as a semi-proprietary consumer IR (infrared) remote control communication protocol for consumer el ...

PIC12F1822 + DS3231 + Remote Control

PIC12F1822 is a small microcontroller has only 8 pins which is not enough for building a real time clock using DS3231 with set buttons because the DS3231 needs 2 pins and the LCD screen needs 3 pins, therefore I've only 1 free pin. I connected that pin to an IR receiver and I used a remote control with a lot of buttons where I used only 3 buttons and the problem solved. This post shows how did I build a sim ...

IR Remote Controlled Home Automation using PIC Microcontroller

R Remote Controlled Home Automation using PIC Microcontroller In this project, we are going to use a PIC microcontroller to remotely control few AC loads by just using an IR remote. A similar project IR remote controlled Home automation has already been done with Arduino also, but here we designed it on PCB using EasyEDA’s online PCB designer and simulator, and used their PCB designing services to order the ...
