dagakshayParticipant
first let me clear you are going for “3*3 2-dimensional square array” or “3*3*3 3-dimensional cube array”
if you are talking about 3-d array yes it is possible with at89c51
formula for 3-d array i/o lines = (n*n)+n*(m-1) // if u not using encoder and decoders
where n is size of cude like if y are going for 3*3*3 cube then (n*n*m)
and m is no. of floors.
and also plz specify what excetly you want in that.
dagakshayParticipantcircuitry is quite simple u need to attach RF Tx module(or the modeule which u using) to microcontroller and that micro controller to be interfaced with PC using RS232 in b/w u need a level converter max232/233
at the receiver end just connect your RX module to microcontroller and decode the data what you have send
for example i am send 0001 for forward from Tx
the at Rx end i need to make my microcontroller programme in such a logic that if i recieve 0001 then my machine should go to forward direction.
dagakshayParticipanti can tell you one logic for this,
just make use of hardware interrupt,
declare temp as global variable and keep on incrementing that in your main loop and make it one as it counts beyond six
while(1)
{
temp= temp++;
if(temp>6) //since a dice has only six faces
temp=1;
}
//and in ISR
ISR(INT0_vect)
{
//use case and make your leds(or 7 segment if using) accodingly
}
apply that logic and code yourself for 8051

dagakshayParticipantyou can use any motordriver Ckt (eg: H-bridge using TIP transistors, relays, l293d or l298….)
there are no of reasons that the o/p of microcontroller cant be feed directly to motors, for simply understanding that you can say microcontroller can’t provide that much of current to drive a motor.
dagakshayParticipantwysiwyg_imageupload::wysiwyg_imageupload:141:connect the alalog o/p to buffer or a comparator ckt, and the o/p of that can be feed to microcontroller(8051). AVR contains in built ADC so you can use that if you using AVR microcontroller
dagakshayParticipantuse ht640 and ht648
