AddOhms #7 - Comparing Arduino and Raspberry Pi
The seventh AddOhms TutorialCast has gone “live”. (Gone “uploaded” sounds wrong.) Being able to understand difference between an Arduino and a Pi is a critical point for many new …
Read MoreArduino: De-Bounce a Button with micros() or millis()
The Arduino is fast, humans are slow. When you push down a button, what seems like a single change to slow humans is really multiple presses to an Arduino. This is known as …
Read MoreArduino: Chasing LEDs with millis()
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 …
Read MoreArduino: Timing Code with Millis() as a Stopwatch
Since most Arduino boards do not have debug capability, this limits the programmer to using Serial.prints. A useful piece of information might be knowing how long certain parts of …
Read MoreArduino: Independent On-Off Times with Millis()
When using delay() to flash a LED there is a time for the LED to be on and then off. This makes it easy to have independent control of the “on” and “off” times. The standard blink …
Read MoreArduino Millis() Examples
You’ve recently learned about millis() and can’t way to delete all of your references to delay(). The problem is that you don’t know quite how to convert your code into …
Read MoreA week of Arduino Millis()
By far one of the most powerful functions of the Arduino library is the millis() counter. It is also one of the most misunderstood functions. Mastering millis() can unlock …
Read MoreEAGLE: Clean up the parts list by disabling libraries
Does it take a few seconds every time you click the “ADD PART” button on EAGLE? Tired of scrolling through an enormous list of parts just to find a capacitor? Here’s how you can …
