    i donT have HT12A IC SO CAN I USE HT12E IC ITS WORKING ORE NOT

    • Electronics Lab

      I think it will not work as HT12E has slightly different characteristics.

    its range ?

    2 years ago
    • Electronics Lab

      As it is based on IR emitter and receiver, the range would be in the range of meters as a common TV remote control.
