What enable1&enable2 in pin l293d
40
IC pins are numbered anti-clockwise around the IC starting near the notch or dot.
8-pin 555 timer IC
a socket that is soldered to a printed circuit board, into which a 8 pin integrated circuit package may be plugged to connect it to the circuitry.
D stands for Driver
it can be done using L293d ic , the ic can control two motors. refer the data sheet for the connections and circuit. L293d also has inbuilt H-bridge.
Is it APR 9600 or ARP 9600? If it is APR 9600 sound record/replay IC, check out the link given below. It contains the pin configuration of the IC.
L293D is having 20 pin IC and also 16 pin IC. description of 20 pin is: 1-enable 1 2- input 1 3- output 1 4,5,6,7,14,15,16,17- ground 8- output 2 9- input 2 10,20-vs 11-enable 2 12- input 3 13-output 3 18-output 4 19-input 4 description for 18 pin: 1-enable 1 2- input 1 3- output 1 4,5,12,13- ground 6-output 2 7- input 2 8,18-vs 9-enable 2 10-input 3 11-output 3 14-output 4 15-input 4
basic operation of mobile controlled lies with the functioning of DTMF and L293D driver ic. one mobile phone is used to send DTMF tones to Rx mobile phone and DTMF decoder ic is used to decode the dtmf tones and it sends information to to micro controller which produces response according to program and gives control to l293d driver ic.
internal diagram of ic 7812
The 8085 is a 40 pin ic because Intel designed it that way.
The pin diagram of AND gate means the pin diagram of IC 7400. New software came handy to draw such complicated diagrams. You can go to the link in the "Sources and related links" down below and download the smartdraw tool where you can drag and drop such ready made shapes. Corel draw graphic suite is another such tool.
IC 7806 have 3 pins. pin1 - in, pin2 - GND, pin3 - out... It provides regulated 6V DC supply...
To identify pin connections on an AND gate IC chip, refer to the datasheet provided by the manufacturer. The datasheet will have a pinout diagram showing the location and function of each pin on the chip. Additionally, you can use a multimeter to test for continuity between pins to confirm their connections.
