Back when I was going to electronics school in the 80’s I built and installed a Night Rider lighting system in a friends camero using a bi-directional shift register to control the lighting effects. When I started experimenting with the Arduino and learned about how to control shift registers with the Arduino I wanted to simulate the Night Rider.
In this project I use three shift registers to control 24 leds. The registers are connected together by taking serial out pin (pin 9) of the first shift register to the serial data input (pin 14) of the second register. Next you take the serial out pin (pin 9) of the second shift register to the serial data input (pin 14) of the third shift register.
Each Monday is ArduinoMonday here at Adafruit! Be sure to check out our posts, tutorials and new Arduino related products. Adafruit manufactures the Arduino right here in the United States in cooperation with arduino.cc. We have a huge selection of Arduino accessories and all the code and tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
