This variation on the For Loop example shows how to use an array. An array is a variable with multiple parts. If you think of a variable as a cup that holds values, you might think of an array as an ice cube tray. It’s like a series of linked cups, all of which can hold the same

In this project, you’ll learn to read an RFID tag using the Innovations ID-12 reader and an Arduino Duemilanove. Step 1: Let’s Get Started! We’ll be using the ID Innovations ID-12 to perform the task of reading an RFID tag. At a minimum, it requires +5V, ground, and a digital pin (on the Arduino) that

This example shows how to use the tone() command to generate notes. It plays a little melody you may have heard before. Circuit image developed using Fritzing. For more circuit examples, see the Fritzing project page Connect one terminal of your speaker to digital pin 8 through a 100 ohm resistor. Connect the other terminal to ground.

What is an ACEDUINO? It is the Philippine Arduino clone. See pic 2 and 3. Quote from Fall Electronics: If you have already tried you have found out you can’t use the ATTiny chips in Arduino. This is because it doesn’t have the cores for the chips. A core in this context is a bunch

This is one of the first projects I have made with Arduino. It’s a little siren with a LED that fades and blinks on and off. It demonstrates basic use of LEDs and speakers. Also check out this article: 8-Pin Programming Shield Constructive criticism is appreciated! Let’s get started! Step 2: Solder jumper wires

A couple of weeks ago, I published a great little controller module that provided 6 relays able to be controlled from a computer via a network. After I published it, I got to thinking that the same basic design, with a couple of changes could be pressed into service as a garden watering system controller.

am just finishing up a project at work, which requires two water tanks to be maintained at 180F. Each tank has twin 1500 watt, 240vac heating elements, each controlled by a SSR (Solid State Relay). My Arduino Mega 2560 reads two DS18B20 temp sensors (one in each tank), and maintains the temperature with a 5

In this instructable, I will show you how to make a simple Simon Says Game using an Arduino. it’s not just simple but we can get a psychological benefit. I have a bad memory to remember something fast or a new things. So this project really suitable for someone like me. hahaha We’re gonna using

Update: I’ll add some clarifications after reading comments on various forums. It doesn’t need a 70Mhz ARM CPU, all it does is shift bits into a shift register, that’d be a total waste. There aren’t 16 CPU’s. the slices are designed to be either slave or master, just one ATMega328P chip, they’re chained together, each

Theremin is one of the most exiting musical instruments ever made, mainly because of its “quite odd” playing method. Infact, its working principle is based on near-filed coupling between the hands of the theremin player and two metal antennas, used to determine the pitch of a variable-frequency oscillator and to adjust the volume of the output signal, respectively. Several theremin
