TV Tuner IR remote with a PIC16F684

Friday, July 22nd, 2016

Tahmid built a TV tuner IR remote with a PIC16F684: I then proceeded to write an IR transmitter using the PIC16F684 (using the MPLAB X IDE and XC8 compiler), following the timing information from the extended NEC protocol. In order to connect all the keys, I connected them in matrix keypad form....

Infrared Receivers – signal lag and distortion

Friday, March 28th, 2014

The crew from AnalysIR writes: Many electronics enthusiasts will be familiar with how Infrared receivers demodulate IR signals. In this post we show a visualisation of the time lag and distortion of the signals as they pass through the IR receiver for demodulation and noise filtering. Most DIY projects use...

Parallax Propeller discriminates Walsh-modulated IREDs

Sunday, April 7th, 2013

Parallax Propeller guru Phil Pilgrim has posted this IR sensor/discriminator project on the Parallax Propeller forums. "Almost everyone here is aware of the advantages of modulated IREDs for rejection of background IR fluctuations and line-frequency noise from artificial lighting. Typically, the IRED modulation occurs at 38 kHz, to which the...

STB Zombifier adds IR remote control to TV box and monitor

Saturday, March 16th, 2013

When Ivan changed his TV provider they required the use of a SetTopBox(STB) as a receiver. Since it had HDMI output, he decided to use an old Philips 230C1 monitor as a TV screen. The monitor, however, was not controlled by the STB and had to be switched on and...
