November 19, at 2: Last but not least, a video demo showing the operation of 74HC Shift Register. June 11, at You are commenting using your Facebook account.

8-Bit Parallel In/Serial Output Shift Registers

You need a 0. Dear Object datashert 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 Maria, sorry for the late reply. James July 31, at 5: If you would like datasbeet cascade 74HC, the only modification you need to make is add the number of 74ls1165 depending on how many you are using.

From there, if you able to read the correct input from your buttons, then its just the display code you need to work on. Another thing that you can try is, first make sure you read what is exactly send from the shift register.

By continuing to use 74lls165 website, you agree to their use. This gives you a flexibility when to read the input to the shift registers.

You can can also change it into pull down resistor network connection. Datashet, you need to send the clock pulse to the shift register in order to obtain the serial output.

Maria November 19, at 2: November 27, at 9: 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. If you are using other display, you may need to change to code for the display. Notify me of new posts via email. Notice that I am using a datasheet up resistor of 10k ohm on all the inputs. However, you would need eatasheet set the clock enable before clocking out the data.

Why have you left out the decoupling capacitors? This will stop the circuit being unreliable especially as you chain more chips. December 16, at 9: You can refer there on how to use two 74HC to increase the number of input pins.

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. This site uses cookies. Blog Statshits. Very nice But, with two 74hc cascade case, how would be the code for this case?? The input pins of the shift registers are pin 11 to 14 D0 to D3 and pin 3 to pin 6 D4 to D7. After the clock is enabled, the parallel input data will be sent out in eight clock pulses.

After discussing about the input and output pins, let us move on with the control pins.

The input voltage acceptable range is between GND to Vcc, where maximum allowable voltage for Vcc is 7V according to the datasheet. Initially, you need to make the parallel load input high. Besides, you want to stop reading the inputs while serially sending the output.

J Dacampo November 27, at 9: January 8, at 8: 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.
