DIY Arduino Oscilloscope with the Nokia 3310 GLCD screen

I’ve seen videos on YouTube using an Arduino and a Graphical LCD screen (GLCD) to create a simple Oscilloscope. The annoying thing is that I found no help whatsoever on how to build one. I spent a few days figuring out how to use the Nokia 3310 LCD screen and then figuring out how to sample an analog port to create a fun oscilloscope effect. Read More…

Arduino Arrays and Recursion Tutorial

Arduino 6 AI temperature scanner with LCD display

I had a need for a temperature scanner to troubleshoot overheating on my Duramax LB7 pickup while towing. A commercial solution to collect 6 temperatures may have run me over a thousand dollars so I ordered some thermistors and for about 40 bucks in parts made one myself. Read More…

Automatic chicken door version two.

As it is getting cold again and my chickens made it through the summer just fine, it is time to revisit and revitalize my automatic chicken door.

The older model was a large door that slid on a track that would get leaves, snow, and ice messing the whole thing up. Also the mecanisim that opened the door was a string that tension was held on with springs, the string would knot up and stop working, blowing the fuse sometimes. Read More…

Netduino Tutorial, Knob and Sweep

In this video I show how to connect a servo to a Netduino and also how to program the servo library into a new solution. The sweep program will drive the arm of the servo back and forth while the Knob program will move the arm of the servo when you turn a potentiometer. Read More…

Arduino Servo Tutorial, Knob and Sweep

In this video I show how to connect a servo to an Arduino and also how to load the sample servo programs included with the Arduino software. The sweep program will drive the arm of the servo back and forth while the Knob program will move the arm of the servo when you turn a potentiometer. Read More…
