74HC595 8 bit Shift Register

Have you ever wondered how people made their projects controlling tons of LEDs with just a single Arduino? Controlling all the LEDs individually requires a lot of pins. So, now I am going to introduce you to shift register. In this tutorial the shift register that we are going to use is 74HC595, 8 bit shift register. By using shift register, you expanded a lot of output pins from your Arduino, that is the best part! Continue reading “74HC595 8 bit Shift Register”
