After buying a Nanode (an Arduino-compatible board with ethernet built-in) last weekend, we’ve been trying to work it out by making a couple of simple examples, the ‘Binary Dice’ is the first one with input and outputs. A note, this code example is based on the one from the book Arduino: A Quick-Start Guide by […]
Now with more LED. Arduino mega powered breathalyzer using the MQ-3 sensor. A relative gauge for judging how intoxicated you are. NOT TO BE USED AS MEANS OF BREATHALYZING NEVER DRINK AND DRIVE. This is more of a device to encourage one to drink more. The MQ-3 can’t achieve the accuracy to register exact […]
Analog sensors produce an analog (continuous) voltage that typically varies from 0 to 5 volts. They have three wires – ground, power, and signal (typically red, black, and white, respectively). Examples shown below include: Potentiometers Proximity Accelerometers Ribbon Bend Pressure Light Temperature Sound Multi-touch Touch Other Potentiometers Potentiometers typically measure rotation or linear travel, and […]
his project is mainly based in this one from Glaciar Wanderer. I just liked his idea and worked it on my own. (I think this guy and me would be friends, as the projects he has in his photography category are things I’ve been wanting to do since I got my Arduino. I will not […]
Here is a quick write up on how to use the tymkrs “Turn Me” rotary encoder. This supports the “push down” feature of the tymkrs kit.

Let’s say that you’re trying to drive a few Nixie clock tubes, or you want to make a strobe light. A variable high voltage DC power supply from 50-200+ volts may be required. Transformers are terrific, but difficult to find the right one and a pain to wind. Why not use a boost converter? They’re […]
This is a quick arduino project that is great for beginners. Enjoy! There is a video on the last step! Step 1: What you Need To build this project you will need: 10 LEDs, any color will do. Some wire, I used a ribbon cable I had Most importantly, an Arduino Perhaps some electrical tape […]
Hi! Kaeru no Ojisan is back with Car No.06. Car No.06 is a Programmed Automatic Driving Car with following procedure; – Simulate the Car Trajectory based on the Target Passing Points. – Drive automatically as simulated using Reflective Photosensor and Gyro Sensor . – Adjust Car Position to the starting point using Web Camera, after […]
Have you wanted to make a sweet Cylon/Knight Rider (Larson) Scanner effect? But you don’t want to use up all of your Arduino IO pins? Well, you can make a nice 8 LED Scanner with a shift register IC. In this tutorial we’ll be using the 74HC595 8 Bit Shift Register, and this is what […]
The 3D LED Cube is a really cool device that enables you to see in three dimensions, get some depth perception and has 512 LED’s or 512 pixels. It is based on an Arduino Uno which is an Atmel AVR microcontroller on a development board with some standard interfacing pinouts that allow you to quickly […]
