Now I know that it is better if we can include a 0. May 11, at 7: After the clock is enabled, the parallel input data will be sent out in eight clock pulses. December 19, at Join 1, other followers.

Fill in your details below or click an icon to log in: One of the advantages that need to be stressed on is that by using only four pins, I can get eight input pins. Schematic on how to cascade the shift register will be shown later on.

June 11, at Thanks for the kind words. If you need to code for a bigger project, I suggest try simpler example and slowly add in the other parts.

You can can also change it into pull down resistor network connection. January 11, at 9: Hi Maria, sorry for the late reply. As I have given lcd. You are commenting using your Twitter account. In order to ease the process datashet reading data from shift register, I am using an Arduino built in function which is ShiftIn.

December 19, at 9: If you are using other display, you may datxsheet to change to code for the display. December 30, at 4: Besides, you want to stop reading the inputs while serially sending the output. You can refer there on how to use two 74HC to increase the number of input pins. A summary of the shift register operation is shown is the timing diagram below. Of course, you need to do some manipulation on the results that you obtained from each shiftIn.

Notice that I am using a pull up resistor of 10k datasheer on all the inputs. Maria November 19, at 2: To cascade between two 74HC shift register, all you need to do is to connect the Serial Output Pin 9 of first stage into Serial Input Pin 10 of the second stage. ShiftIn data,clock,order — The data is the input pin on Arduino to datzsheet the output from shift register whereas the clock is the pin connected to shift register clock.

Dear Object means the instrument which is a digital keyboard for 47ls165 playing and its display lcd is not available and its very much important to me, its my first keyboard therefore I want to get the display data or display screen of the instrument on arduino lcd. July 31, at 5: Blog Statshits. Hi J Dacampo, Thanks.

Initially, you need to make the parallel load input high. This will stop the circuit being unreliable especially as you chain more chips. J Dacampo November 27, at 9: December 17, at Very nice But, with two 74hc cascade case, how would be the code for this case??
