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. J Dacampo November 27, at 9: May 11, at 7: January 8, at 8: Hi J Dacampo, Thanks.
ShiftIn data,clock,order — The data is the input pin on Arduino to read the output from shift register whereas the clock is the pin connected to shift register clock. Besides, you want to stop reading the inputs while serially sending the output. By continuing to use this website, you agree to their use. Notice that I am using a pull up resistor of 10k ohm on all the inputs. 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 need a 0. To find out more, including how to control cookies, see here: If you are using other display, you may need to change to code for the display.
Thanks for your kind reply… See I have followed you and understood your line 39 to 51 is printable characters.

June 27, at 9: 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. You can cascade a lot of shift register to get tons of inputs.
December 19, at 9: January 11, at 9: Now Datasheett know that it is better if we can include a 0. If you need to code for a bigger project, I suggest try simpler example and slowly add in the other parts.
Recently I just updated the Arduino Piano project, https: Schematic on how to cascade the shift register will be shown later on. December 30, at 4: Initially, you need to make the parallel load input high. December 16, at 9: After the clock is enabled, the parallel input data will be sent out in eight clock pulses. Now, let us look into detail how to use the shift register.

Why have you left out the decoupling capacitors? Create a free website or blog at WordPress. Hi Sammy, please refer to the code in the article, line 39 to 51 is how the dataxheet are converted into printable characters on the LCD. 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.
