![]() ![]() 74hc595 features it is a shift register with 8 bit serial input and 8 bit serial or 3 state parallel outputs. the shift register holds what can be thought of as eight memory locations, each of which can be a 1 or a 0. the chip is of a type called a shift register. The 74hc595 shift register save subscribe before i go through the code, let's have a quick look at what the chip is doing, so that we can understand what the code has to do. every time the 74hc595 receives a clock pulse, two things happen: the bits contained in the shift register are shifted to the left by one position. the first is referred to as the shift register, and the second as the storage latch register. The 74hc595 has two 8 bit registers (which can be thought of as “memory containers”). it should have the same leads to power and ground. starting from the previous example, you should put a second shift register on the board. In this example you'll add a second shift register, doubling the number of output pins you have while still using the same number of pins from the arduino. turning it on make the following connections: gnd (pin 8) to ground, vcc (pin 16) to 5v oe (pin 13) to ground mr (pin 10) to 5v this set up makes all of the output pins active and addressable all the time. The first step is to extend your arduino with one shift register. Arduino Ile 74hc595 Shift Register Kullanımı Mcufreak Arduino
