This example shows how to use the tone() command to play different notes on multiple outputs. The tone() command works by taking over one of the Atmega’s internal timers, setting it to the frequency you want, and using the timer to pulse an output pin. Since it’s only using one timer, you can only play

This example shows how to use the tone() command to generate different pitches depending on which sensor is pressed. Circuit Connect one terminal of your speaker to digital pin 8 through a 100 ohm resistor, and its other terminal to ground. Power your three FSRs (or any other analog sensor) with 5V in parallel. Connect each

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.

On this instructable I will try to show how to interface a RFID sensor with the Arduino. I am using the RFID sensor from seeedstudio the serial version of it. There are a few parts you will gonna need. I also bought some RFID keys. UPDATE: Now it works with IDE 021 Step 2: Plugging

The Twittering office chair “tweets” (posts a Twitter update) upon the detection of natural gas such as that produced by human flatulence. This is part of my commitment to accurately document and share my life as it happens. For more in depth theory, please see the next step entitled Theory. See the results of the

Hello! This is the cheapest and easiest way to make a two-dimensional laser show projector. It uses just one pivoting mirror, powered by the focusing mechanism from a CD or other optical drive. They said it couldn’t be done, but Ljudmila‘s skunkworks GRL research facility delivers anyway! 😉 This design was first discovered in 2006

This is a self sufficient Arduino board, which is powered by harnessing solar power and using a 9V rechargeable battery. It is perfect for anyone who is interested in doing Arduino projects that do not require a computer or any power supply. You can take this to the most remote places for any project. Step

I’ve always been interested in monitoring my local weather, and noticed the difference between what weather.com and accuweather.com think my local weather is, and what I see out the window. I also wanted better control over my heating and A/C system. As a computer and electronics nut, I’ve been playing with the Arduino Microcontroller, and

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
