Planning circuit layouts with DIY-LC

Matt 0 Comments

At some point there will be an Arduino project that is just too good to take apart. You can’t leave it on the breadboard forever, but building a circuit on prototyping board can be confusing for beginners.

The best way to make this process easier is to plan the layout of your circuit before you start building. I used to use graph paper to do this, but then I found a great free tool called DIY-LC.

Arduino Tip: 7 segment LED display with 4094 shift register

Matt 0 Comments

This is my first Arduino example sketch – hopefully the first of many.

This sketch allows you to control a 7 segment LED display using an Arduino and a 4094 shift register. Only 4 data pins are used on the Arduino, rather than 8 if you were to control the 7 segment display directly. For this example I used a common cathode LED display.

Simply copy the code below into the Arduino IDE, build the circuit explained in the notes and watch the numbers count up.
