In the third Arduino Tutorial I discuss one of the many ways that you can expand your outputs on the Arduino. In this case, by using a shift register, I am able to use three Arduino pins to control 8 LEDs.

I got a few requests for a circuit diagram, so this video should help you out.

In this 3rd part of our 7-segment to arduino connection walkthrough tutorial we use a 595 Shift register to display the numbers. Walking through all the steps of connecting, how to count binary when sending it serially to the 595 and how to write the code to display 0-9 numbers.

This is a demo of the example included with the ShiftPWM library for Arduino.

With ShiftPWM you can control up to 768 outputs with PWM.

A new improved version can be found at elcojacobs.com/shiftpwm

Want to control those standard, off-the-shelf DC motors in any way possible with an Arduino? Look no further, this video will tell you how to do just that! The L298 (or l298N) motor driver IC is a great little device that can control 2 motors, and supply up to 2 amps per motor - perfect for little robots running around!

In this project I will be using the 74HC595 to extend I/O's from a PLC for the purpose of driving several segment displays. Instructions, schematics, and a parts list is available at wilsonmj.net

A little project of mine. Disregard everything on the breadboard. It has nothing to do with this project, I just didn't want to take it all off.

Shift Bit Registers can be a little tricky to map out and setup. I designed this simple bit of code to help you do just that. A simple bit shift operation that sends a HIGH signal down each of the Shift Bit Registers pins in turn. i.e. shiftOutDisplay
I've also developed this very simple method that goes hand in hand with the code and should be a good starting point for anyone who is not too familiar with Binary.
Finally, I've added some useful code to display the map that you've created. i.e.

I hope you find it useful, I know I've had a lot of fun with this stuff :)

This video looks at serial to parallel conversion in digital electronic circuits. In particular it shows how we can drive a sequence of LEDs using a single pin of the Arduino. Also, it discusses the difference between latched and unlatched serial to parallel converters. The particular ICs that are examined are the 74HC164 and the 74HC595 (latched), where the video demonstrates how to drive 8 LEDs using a single pin and 16 LEDs using two pins of serial data. This video is part of an introductory module on digital electronics. The associated content can be found at http://www.eeng.dcu.ie/~molloyd/EE223/

Working on a project where you need to display something (like data/debugging info)? Why not use an LCD! In this video, I go through various aspects of controlling the device with an Arduino, including setting different types of cursors, toggling the display and even creating custom characters!

This week we take a look at using a shift register to control a single 7 Segment Display then we take a look at the Maxim 7219 chip that is designed specifically for controlling up to 8 7 Segment displays or an 8x8 LED matrix. Plus you can connect these chips serially like a shift register to add control of an additional 8 displays for each additional chip.

The following lesson is for beginers who dont even know how to start using Codevission AVR for coding a Chip,hope this helps.

Simple demonstration of working of 74HC595 Shift Registers and using them to control LEDs on an 8x8 LED Matrix Display.

The Column and Row Lines in this circuit are fixed to VCC/GND, and a single PUSH-BUTTON is used to send the CLOCK Signal for shifting.

This is just one of the steps in moving toward controlling such Displays via a micro-controller.
