i want projects on matlab which are already executed so that i can have program can u help me up plzzzzzz

that means that means i have to connect a 1kohm resistor and led between 5th pin of opto and 9v .....is this what you are saying can u reply me

as i m going to connect this i am getting some malfunctions in circuit ?can u help me by pressing only 7 also i am geetting output at 1st pin...

the circuit is working by just pressing 7 but can u suggest any modifications if any to get ouput by only perssing 1,4,7

R1-7-9=1Kohm R2-3-4-5=100Kohm R6 =10Kohm R9 =47Kohm IC1 = 4066 IC2 =4N25 Q1-2=BC550 S1...11=Push button sw or keyboard S12=Push button normal closed All resistors is 1/4W 5% can i get an...

ya it is 4066 optocoupler ic is 4n25

can u explain the detailed operation can u tell me wat is the value of R8,R9 RESISTORS

hi, sir i want to know more about this circuit(as i m doing it as my mini project) can u tell me whether this circuit works or not also please...

vcan u tell me some more about it

ground isolation? i cant get u clearly? can u xplain clearly plzzzzzzzzz
