how you can take a computer u hv old (power supply unit) and turn it into a power supply that will power your Arduino and give you all the amperage you need as well as your standard 3.3 volts, 5 volts, and 12 volts for any accessories/electronics used on your breadboard And arduino power ,led […]

In the previous post, I outlined some Arduino code to generate tide height predictions for a NOAA tidal reference station. Now let’s do something useful with this newfound functionality. In the experiments I run, it’s useful to keep intertidal animals like snails and limpets on a natural tidal cycle. In addition, some animals like high-shore

Sometimes I just do not have time to connect to the internet and check current weather conditions. This is the reason why I made this indoor LCD weather display based on Atmega328 Arduino MCU. The circuit board consists of two LP2950 voltage regulators, MCU, four buttons, ENC28J60 Ethernet module and LCD12864 graphic display module. The

This project is a subset of my idea of an interactive wall.. so this is an interactive wall-piece.. What does it do ? Mine is a touch activated light display. How does it work? It is controlled by an Arduino UNO which senses the inputs and turns on the respective outputs. Step 1: Building the
I came across these Force Sensitive Resistors. I like them a lot and I wanted to do something with them, may be making them more usesable than standing on the breadboard. Few months ago, I created the pocket-sized RevIO – Arduino Compatible and having fun with it since then. While playing with these two, I decided
I have a “through the Looking Glasses” idea of making another version of Palm Arduino. Since this design derived from Palm Arduino, I will called it Palm Arduino II. This Palm Arduino, the Second, will be the combination of Palm Arduino and Portable 5V Voltage Regulator. So that everything is staying together closely in the same package!
ButtonHero is a game made on an Arduino that involves the use of buttons, LEDs, wires, and resistors. In this game, you have to hit the corresponding button to the light that is randomly selected before the light changes. You start with 5 lives and missing or being too slow subtracts one life. The high
How to: Speaking Clock Hello 🙂 Setup and Procedure The wave shield is interfaced with the Arduino Mega 2560 as normal. A couple of pins were remapped because the wave shield was initially made for a different device. The DAC pins were remapped to pins 22,23,24 and 25 on the Arduino board. The WaveHC library also
My wife and I have wanted to raise chickens(for the eggs) and we finally decided to do it this spring. I have read a lot about pastured chicken and wanted to create a mobile coop so that the chickens would not destroy the yard. I have a fairly decent sized yard for the burbs so
Mobile Chicken Coop with some automation using Arduino Continue Reading
Step 1: What You’ll need A linux web-server with PHP, an arduino, a relay and some other components. Step 2: Upload your code to the arduino Upload the following code to your arduino: void setup(){ Serial.begin(9600); } void loop() { if (Serial.available() > 0) { char inByte = Serial.read(); if(inByte == ‘1’){ digitalWrite(13,HIGH); } else if(inByte == ‘0’){
