When it comes to transistors, there are only so many things a multimeter can measure. The DCA Pro from PEAK Electronics makes short work of testing parts like a transistor. This …

Last week I had a detailed Arduino tutorial on software pulse width modulation using millis() and micros(). Why? Because I wanted to create a Proper Larson Scanner, with …

The Arduino Uno has six pins dedicated to Pulse Width Modulation (PWM). PWM is great for analog-like control for the speed of motors or LED fading. But what if you want to control …

How to blink (or flash) a LED without delay() and detect button pushes One of the limitations of the delay() function is that nothing else can really be done. This presents a …

A popular LED project is the “Larson Scanner.” This scanner emulates the effect seen on KIT from Knight Rider and the Cylons in Battlestar Galactica. The code is usually written …

Status: Completed GitHub: https://github.com/baldengineer/8x6-LED-Matrix-Shield Abstract After getting a couple of flashing lights working on a microprocessor, the next fun project …

Short build-lapse video of building up the front panel “matrix” used in BinBoo. This isn’t a true LED matrix. Instead it combining all of the LEDs into a common Anode, since the …

Several months ago I started a project to build a Binary Clock, using a Laser Cut enclosure. The plan was to use Ponoko’s laser cutting service. Looking through the materials …

After working through these exercises, check out this article on how to avoid rollover or reset mills(). After learning how to flash a single LED on your Arduino, you are probably …

TLC5940NT Painter Board This screen shot is an all-layer view of my TLC5940 painter board. The 1st draft featured two TLC5940s, but I decided it made the board too large. Instead, …
