This transmitter has range of 10-30 meters, 10 Jumper selectable addressing provide security and allows creation of multiple transmitter and receiver Encoder and Decoder has 10 Address lines and they must match in order to transmitter and receiver to communicates to
Read more4 Channel Infrared (IR) Remote controller is using HT12A and HT12D encoder / decoder chips from Holtek. Supply – Transmitter : 3 to 5 VDC, 5 V @ 20 mA & Receiver : 5 VDC @ 200 mA Output : 4 channel Latch or Momentary on board Jumper for selection Crystal based oscillator for reliability of operation Jumper selectable 8
Read moreRF Based DC Motor Direction Controller project provides an easy way to control the direction of your DC Motor connected to the receiver. This project has been design around HT12E and HT12D encoder / decoder chips from Holtek. With jumper selectable address on the receiver and transmitter we can control multiple motors in one area without interference with one remote.
Read moreLUX Meter project has been design to measure the illumination. Illumination is luminous flux falling on surface area of photo diode. This illumination converted to corresponding voltage using Op-Amp circuit. Specifications Supply 9 VDC PP3 Battery @ 20 mA Onboard Photo Diode Onboard preset for calibration Range selection via jumper 10mV/LUX, 1mV/LUX, 0.1mV/LUX Interfacing
