Notice that I am using a pull up resistor of 10k ohm on all the inputs. December 30, at 4: Thanks for your kind reply… See I have followed you and understood your line 39 to 51 is printable characters. Maria November 19, at 2: If you need to read the inputs to shift register and display it on 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.

May 11, at 7: Why have you left out the decoupling capacitors? Now I know that it is better if we can include a 0. You can cascade a lot of shift register datashret get tons of inputs.

In this tutorial, I am going to show another shift register which is capable of expanding input pins. Hi Maria, sorry for the late reply. Build your own Arduino Uno. December 1, at 8: Create a free website or blog at WordPress.

Notify me of new comments via email. Hi Sammy, please refer to the code datassheet the article, line 39 to 51 is how the bits are converted into printable characters on the LCD. If you need to code for a bigger project, I suggest try simpler example and slowly add in the other parts.

This gives you a flexibility when to read the input to the shift registers.

You are commenting using your Facebook account. 47ls165 pin that is useful especially when you want to cascade a few shift registers together, which is Serial Data Input DS.

Email required Address never made public. December 19, at A low signal will triggers the input to be loaded into the shift register. 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.

Hi J Dacampo, Thanks. January 8, at 7: After discussing about the input and output pins, let us move on with the control pins.

If you would like to cascade 74HC, the only modification you need to make is add the number of shiftIn depending on how many you are using. Thanks for the kind words. Besides, you want to stop reading the inputs while serially sending the output.
