i tried that one the range | Microcontroller › 8051 › using 8 LEDs to display 30 letters with 8051 › i tried that one the range April 15, 2012 at 5:36 am #7452 D.V.G. KrishnaParticipant i tried that one the range of IR led is not sharp so the starting point of the display is oscillating in between a 2 inch range.and not stable at higher speed when i used on a table fan. so i need a sensor that is sharp and stable at higher speed
