Aralar December 19, at 9: 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. A low signal will triggers datashete input to be loaded into the shift register. However, it is recommended to operate the chip at 5V. In this tutorial, I am going to show another shift register which is capable of expanding input pins. Join 1, other followers.

Features, Applications This device an 8-bit serial shift register which shifts data in the direction of QA toward QH when clocked. These registers also feature gated clock inputs and complementary outputs from the eighth bit. Clocking is accomplished through a 2-input NOR gate, permitting one input to be used as a clock-inhibit function.
The clock-inhibit input should be changed to the high level only while the clock input is HIGH. Parallel loading is inhibited as long as the load input is HIGH. Specify by appending the suffix letter "X" to the ordering code. Inputs Load Inhibit A The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings.
The "Recommended Operating Conditions" table will define the conditions for actual device operation. Note 6: Not more than one output should be shorted at a time, and the duration should not exceed one second. These octal bus transceivers are designed for asynchronous two-way communication between data buses.
The devices transmit data from the A bus to the B bus or from the B bus to the A bus depending upon the level at the direction control DIR input. The enable input G can be used to disable the device so that the buses are effectively isolated.

Another thing that you can try is, first make sure you read what is exactly send from the shift register.
