Hi J Dacampo, Thanks. From my understanding, you have the buttons well connected to the shift register and the output of shift register is also connected to the Arduino.

Thanks for your kind reply… See I have followed you and understood your line 39 to 51 is printable characters. Notice that I am using a pull up resistor of 10k ohm on all the inputs. December 17, at If you are using other display, you may need to change to code for the display.

However, you would need to set the clock enable before clocking 74la165 the data. After the dataxheet is enabled, the parallel input data will be sent out in eight clock pulses. You can cascade a lot of shift register to get tons of inputs. If you need to read the inputs to shift register and display it datasyeet your HD using Arduino, the code provided above would work for you.

June 27, at 9: You can refer there on how to use two 74HC to increase the number of input pins. Email required Address never made public.

Hi Maria, sorry for the late reply. If you would like to cascade 74HC, the only modification you need to make is add the number of shiftIn depending on how 74ls1665 you are using. Change the code to display it using your serial monitor.

December 19, at 9: The input pins of the shift registers are pin 11 to 14 D0 to D3 and pin 3 to pin 6 D4 to D7. You can can also change it into pull down resistor network connection.

After discussing about the input and output pins, let us move on datsaheet the control pins. Schematic on how to cascade the shift register will be shown later on. You are commenting using your WordPress.

December 1, at 8: Moreover, it can be cascaded, thus you can have any amount of input pins with only four pins with the help of this shift register. J Dacampo November 27, at 9: This site uses cookies. Very nice But, with two 74hc cascade case, how would be the code for this case?? December 16, at 9: ShiftIn data,clock,order — The data is the input pin on Arduino to datasjeet the output from shift register whereas the clock is the pin connected to shift register clock.

Build your own Arduino Uno. Dear Object means the instrument which is a digital keyboard for music 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.

Notify me of new comments via email. One of the advantages that need to be stressed on is that by using only four pins, I can get eight input pins. A summary of the shift register operation is shown is the timing diagram below.

Thanks for the kind words. May 11, at 7: November 27, at 9:
