74HC595is a type of Shift Register, and it is the most famous among all. As there are limited I/O pins in most microcontrollers, there will come a time that you’ll run out of pins and this is where the Shift Register comes in handy as it helps expand the number of I/O pins in your Arduino Uno.
Using 3 input pins, The 74HC595 can substantially control eight separate output pins.
In this lesson, you will learn how to use a 74HC595 with Arduino and control 8 RGB leds.
Let’s Start!
STEP 1: Get the following components:
STEP 2: Placing the components to the breadboard.
STEP 3: Uploading the 74hc595 Arduino Code.
- Press the Upload button to send the codes to your Arduino board.
- After you upload the codes, you will see the LEDs light up one by one.
