July 31, at 5: From there, if you able to read the correct input from your buttons, then its just the display code you need to work on. The input voltage acceptable range is between GND to Vcc, where maximum allowable voltage for Vcc is 7V according to the datasheet.

The input pins of the shift registers are pin 11 to 14 D0 to D3 and pin 3 to pin 6 D4 to D7. December 16, at 9: Now, let us look into detail how to use the shift register.

If you need to code for a bigger project, I suggest try simpler example and slowly add in the other parts. 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.

This ratasheet stop the circuit being unreliable especially as you chain more chips. In this tutorial, I am going to show another shift register which is capable of expanding input pins. Change the code to display it using your serial monitor.

November 27, at 9: Hey zxlee, great article, It datashet me a lot. November 19, at 2: J Dacampo 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. However, you would need to set the clock enable before clocking out the data. 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. Join 1, other followers.

Hi Sammy, please refer to the code in the article, line 39 to 51 is how the bits are converted into printable characters on the LCD.

Schematic on how to cascade the shift register will be shown later on. James July 31, at 5: Email required Address never made public.

Now I know that it is better if we can include a 0. By continuing to use this website, you agree to their use. January 8, at 8: In order to ease the process of reading data from shift register, I am using an Arduino built in function which is ShiftIn. Another thing that you can try is, first make sure you read what is exactly send from the shift register.

Another pin that is useful especially when you want to cascade a few shift registers together, which is Serial Data Input DS. Hi Maria, sorry for the late reply. January 11, at 9: You can cascade a lot satasheet shift register to get tons of inputs.
