Transmit & Receive Infrared Signals With Your PC Serial Port using PIC12F508

We no longer manufacture or sell the original Air-Byte IR transceiver, so we're releasing the code & circuit design here for hobbyists and students looking to build a simple IR transceiver. Note that the parts used here are not critical. I.E. the NPN darlington transistor driving the infrared LEDs, PNP transistor used for inverting the IR detector output, voltage regulator, LED's, and most every other c ...

Infra-Red Transmitter using PIC12F675 microcontroller

Description This project uses a MicrochipPIC microcontroller and an Infra-Red LED to act as a PC controlled cable TV changer. Operation The purpose of this is so that my MythTVPersonal Video Recorder (PVR) can change channels on the cable TV set-top box when making a recording. A very simple program on the computer sends the channel number over RS232 to this PIC based IR transmitter which creates the correc ...

An AVR microcontroller based Ethernet device

Ethernet has traditionally been a quite complex interface. All Ethernet chips until today had 100 pins or more, where difficult to find in small quantities and difficult to use from a small microcontroller with little memory. Microchip has changed the world with their new ENC28J60 Ethernet chip! The ENC28J60 is a small chip with 28 pins only and has a SPI interface which is easy to use from any microcontrol ...

Wireless 10 channel receiver using PIC16F630

This project can steer 10 different things wireless with the use of a normal TV-remote-control with the RC5 protocol, from manufacters like Philips, Grundig and Marantz. If the Proton PIC Basic compiler is available, then you can ofcourse change the number of channels. Use it as follows: When 'TV' mode is selected on your remote-control, you can with the buttons 0 through 9 on it, steer 10 outputs on and of ...

WEBSD using PIC24F microcontroller

WEBSD This is a development board for the PIC24F series of microchip, with: USB ( plug it to any computer) Ethernet ( plug it to the internet) SD card ( save and read all data you will need) I developed this thing as a learning platform, it worked ( still is). So if you always want to go a step further in microcontrollers as i want, it's a nice way of doing it . The problem i had is that microchip examples ...

3-Channel IR Relay Controller with user programmable IR commands for PIC12F629

Description This project is a 3 channel infrared (IR) remote controlled relay driver.  It works with 12-bit SIRC IR signals as used by Sony remote controls. The controller also features the ability for the user to 'program' the commands it will respond to using  the IR remote control.   Each of the three relay channels can also be individually configured for either toggle or momentary switch action. Althoug ...
