Once upon a time, 2 girls greatly enjoyed walking in the rain with umbrellas. They decided the enjoyment of this experience could be maximized by building their own pressure-activated web of LEDs to install under their umbrella. Thus, with the help of an Arduino, some 4051 multiplexers, a lot of wire and a lot of […]
This instructable will show the game TankWars, a web based game played on an iPad that drives a real robot tank to fire lasers at a robot. When you hit the robot target, the game is updated. The tank and the target are Arduino’s equipped with RN-XV WiFly modules, the iPad is using a PHP […]
After this Instructable you should be able to program an A Ttiny85/45 with an arduino. It may sound complex but it really isn’t. After doing some research I could not find to much info on how this could be done. I however did find http://www.instructables.com/id/Program-an-ATtiny-with-Arduino/. This Instructable is my interpretation of what I learned from Randy. Step […]
Using a dual 7-segment display, a DS18B20 temperature sensor and a couple of shift registers I figured that I could build a digital thermometer. Step 1: Temperature Sensor The sensor I’m using is the DS18B20, it’s a 3pin sensor that just requires a single input pin from the arduino. Multiple sensors can be hooked together, […]
The String comparison operators, ==, !=,>, < ,>=, <= , and the functionsequals() and equalsIgoreCase() allow you to make alphabetic comparisons between Strings. They’re useful for sorting and alphabetizing, among other things. The operator == and the function equals() perform identically. It’s just a matter of which you prefer. So if (stringOne.equals(stringTwo)) { [Get Code] […]
This is a project in attempting to improve it predecessor “Freeform Arduino” by putting it in an enclosure and having it serve the similar purposes as “Palm Arduino Kit” and “Palm Arduino II” which I can carry it in my pocket and be available to use, and to connect to easy available power source specifically […]
Hi there. Christmas is coming closer, and I was wondering if I could put some candles in my room to get in the “christmas mood”. But after a friends house burned down of christmas tree candles, I don’t want to burn real candles into my room. So why don’t let the Arduino light for you?! […]
4D Systems makes some really nice serial OLEDS. They aren’t hard to use, but the documentation for them is very scattered. This tutorial pulls together the various pieces i’ve found so that you can get up and running very quickly. Start by skimming through the user manual for your particular 4D OLED. µOLED-128-GMD µOLED-96-G1 µOLED-160-GMD1 […]
At the place I work, we use xymon to monitor of our servers. All of the services monitored are important, but we wanted a separate indicator to simply show the overall health of the most critical systems. Furthermore, we came up with the following criteria: We wanted this visible to everyone whether or not they […]
This example shows you how to monitor the state of a switch by establishing serial communication between your Arduino and your computer over USB. Hardware Required Arduino Board A momentary switch, button, or toggle switch 10k ohm resistor breadboard hook-up wire Circuit image developed using Fritzing. For more circuit examples, see the Fritzing project page Connect three wires to […]
