I've converted the 4 data out remote control car into single data out circuit

This s just for transmitting a single pulse while the switch is pressed.


Anyone pls find whether ths circuit is correct or wrong??????

    #-Link-Snipped-# :
    HT-12E is basically transmitting the status of D0 to D3 to Receiver. So I don't think there is anything wrong if you want to keep D1,D2 and D3 open and use only D0 to transmit the pulse. But yes you may like to either Ground or VCC connected with D1,D2 and D3.

    1. Why you want to reduce the range?
    2. What type of antenna you are using right now?
    3. So your circuit is working properly?
