Temperature Recording Arduino Robot

My son and myself made a little arduino robot that records temperature. He wanted me to draw a robot, I wanted to experiment with blinking LEDs relaying data so a plan was hatched. The way the LEDs work is as follows: Green = lowest temperature recorded, Yellow = highest and Red = current temperature with all readings being in °C. Step 2: Wiring Up I realise now how bad the photograph is but as everything i ...

TiltKey- Write by Tilting

The TiltKey is a keyboard input device based on tilting. Based on the angle that it is tilted at, and the direction it is tilted in, you can write every letter of the alphabet, every number, and every symbol found on a standard US keyboard. Operation is very simple; the LCD display shows the letter your going to write, and pressing the "press" button will write it to your computer. Holding the "shift" butto ...

Relay Finder will let you know, when one phase is missing …

Finder monitoring relays are able to effectively signalize a fault status in a mains line and to prevent damages or undue wear-out. Too high or too low voltage, phase loss or a wrong phase rotation are conditions commonly occurring in an industrial environment. Even though a phase rotation is usually stable, but only one improperly connected lengthening cable is sufficient .... These fault conditions harm t ...

Fading an LED off and on using Arduino

Demonstrates the use of the analogWrite() function in fading an LED off and on. AnalogWrite uses pulse width modulation (PWM), turning a digital pin on and off very quickly, to create a fading effect. Circuit Connect the anode (the longer, positive leg) of your LED to digital output pin 9 on your Arduino through a 220-ohm resistor. Connect the cathode (the shorter, negative leg) directly to ground. image de ...

Wing Tip Extensions for Arduino

Greetings, One late night of web surfing I came across some 45 Degree Extension boards. Thinking to myself “Wow!” that’s cool and then I looked at the price…$27.00 before S&H. “Yikes!” I’ve been looking for an excuse to learn Eagle PCB layout software and this was the project I decided to cut my teeth on…”Wing Tip Extension” was born! Step 1: Layout PCB Layout, I’m sure this took longer than it should h ...

Using an Arduino Uno R3 as a Game Controller

Naturally, the Uno does not natively support keyboard strokes, unlike it's Leonardo brother. Most of Google will tell you you need to do some firmware workarounds and ATMEGA reprogramming just to get it working and the entire ordeal is a mess. If you're like me, you've found that out just after buying one. Here is how to get around all that using a bit of Java coding. The ideal solution would be to purchase ...
