Simple IR Remote Receiver with Decoder
Posted on Saturday, April 30, 2011   •   Category: Remote Control


The function of the device is very simple. Any IR remote than can be programmed to use the Sony protocol will work. The module outputs the device code (TV/VCR/DVD/AUX) and the button pressed, so the device can be used on as many different projects as your remote has devices (usually four). The numeric keys output the number of the key (0 outputs a 0, etc.). The function keys all output unique numbers. Note that not all buttons are available depending on which device you have selected. The VCR setting seems to use most of the keys on the remote. Also note that the first key pressed after the device is powered up does not output what it should. All subsequent numbers are correct. Luckily, all of the numbers so generated make a number different than any of the key codes, so it doesn't cause any problem. This could even be used to let the device know if it has just been powered up or rebooted. I have no idea why it does this.

Build Accurate LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and reset function to make sure the readings are as accurate as possible ... [more]
