hello,
can anyone help me...
i've recently finished my project titled "RF remote controlled robot".
actually the project is dc motor control using RF module and i've fitted wheels to the motors so it works as robot.
i'm attaching the abstract,circuit diagram
remote control transmitter part consists of 4 switches,based on which the controls are sent to the motor to rotate it in desired directions..
in my project i've pulled the TE(14 pin) of HT12E to gnd directly.....
now,my pblm is when i give the following commands at the switches the following is the result expected
0101-forward
1010-bckward
0001-left turn
0100-right turn
1001-left spin
0110-right spin
0010-left back
1000-right back
all these movements are working perfectly well....but only after some delay,
that is when i switch on the supply and press any switch the robot starts rotating in one particular direction and does not stop untill i manually stop it by switching off the power supply (even though i remove my finger by just touching the switch).....same is the case with any switch for abt 3-4 min...
after i manually stop the robot several times...(in abt 3-4 min) everything will be fine
soon after i touch a switch and leave the robot stops and the output is perfect for the above mentioned commands
i dont understand why there is this start up pblm?
can anyone pls help me?
