Proximity sensing LEDs

Monday, August 25th, 2014

Here’s a proximity-sensing LEDs project by Will_W_76.  He writes a complete step-by-step instructions here: So how does this all work? What makes it proximity-sensing? Remember in the explanation above that the photo-transistor acts like a switch. So when the photo-transistor is off, no current is flowing across it to our...

USB IR Toy transmit frequency

Thursday, April 1st, 2010

Most infrared remote controls emit modulated light pulses to activate an infrared receiver. Using modulated IR light helps prevent stray light from messing with reception. Pulses at around 38kHz and 56kHz are common, but many values are used. The USB IR Toy's transmitting LED is driven by a pulse-width modulator...

Easy infrared UART data link

Wednesday, August 26th, 2009

http://www.youtube.com/watch?v=IPs-OYCW3eo Here's an easy way to transfer data with an infrared LED and an infrared remote control demodulator. The example uses an Arduino, but the technique will work with any microcontroller. The transmitting microcontroller powers an IR LED from a pin configured as a 38KHz pulse-width modulator. Another pin configured...
