Project description

Step 1: Shift Register 595 and Outputs The shift register will give to your Arduino an additional 8 digital outputs, by using only 3 pins on your board! Here you can find a simple tutorial with the shift register 595 IC and Arduino uno board. SR 595 and Arduino uno: Pin 8 (GND) to GND Pin 10 (SRCLR') to 5V Pin 11 (SRCLK) to Arduino pin 6 Pin 12 (RCLK) to Arduino pin 5 Pin 13 (OE') to GND Pin 14 (SER) to Arduino pin 4 Pin 16 (Vcc) to 5V QA is the first output - QH is the 8th output. We will connect each output with one screw driver - terminal and with an LED through a 220 Ohm resistor. When…
