Arduino controlled window for cat

I am submitting this instructable to the Arduino challenge. Please remember to vote! My neighbor had a little problem with his cat. It want's to go out and back inside too frequently. Usually he opens just his kitchen window and let's the cat in/out. Usually the cat stays only short periods outside and want's soon to come back inside. And then again out and back in. Okay, he could just let the window open, ...

Homemade Infrared Rangefinder (Similar to Sharp GP2D120) using Arduino

Here is my instructable on how to construct a pretty simple (for some!) short range infrared rangefinder/range sensor. Infrared rangefinders are very useful in a number of projects. The majority of these come from obstacle detection (in robots) or generally detecting distances! The one shown here is only a simple rangefinder and will only really be able to measure about 6 or 7cm infront of the range finder. ...

Arduino Zero

Arduino Zero Overview The Arduino Zero is a simple and powerful 32-bit extension of the platform established by Arduino UNO. The Zero board aims to provide creative individuals with the potential to realize truly innovative ideas for smart IoT devices, wearable technology, high-tech automation, crazy robotics, and projects not yet imagined. The board is powered by Atmel’s SAMD21 MCU, which features a 32-bit ...

Simplest and Cheapest Arduino

Use a ATTiny85 (can be ATTiny45, ATTiny44) to make an Arduino just for US3.00 and name it as Tiny Arduino. Tiny Arduino have only eight pins as shown in figure above, Pin4 is ground (Gnd), Pin8 is 5V (Vcc), Pin1 is Reset, Pin2 and Pin3 originally used to connecting the Crystal. In order to utilize all the IO, the internal oscillator (RC Oscillator) is used to replace the external clock which require a cryst ...

Robotic Eye using Arduino

Hello, This time I will show an application of the infrared sensor module with Arduino. This module (composed of a pair of LEDs, a infrared transmitter and a receiver and an IC that generates a frequency modulated) is generally used to detect obstacles in robots. This module has some advantages over a simple LED emitting LEDs with a photodetector. The principal, in this case is that the emission frequency i ...

MIDI Note Player using Arduino

This tutorial shows how to play MIDI notes from an Arduino. MIDI, the Musical Instrument Digital Interface, is a useful protocol for controlling synthesizers, sequencers, and other musical devices. MIDI devices are generally grouped in to two broad classes: controllers (i.e. devices that generate MIDI signals based on human actions) and synthesizers (including samplers, sequencers, and so forth). The latter ...

Serial Call and Response with ASCII-encoded output using Arduino

This example demonstrates string-based communication from the Arduino board to the computer using a call-and-response (handshaking) method. The sketch sends an ASCII string on startup and repeats that until it gets a serial response from the computer. Then it sends three sensor values as ASCII-encoded numbers, separated by commas and terminated by a linefeed and carriage return, and waits for another respon ...

Trinity Assembly

Hey dudes! Lets build the trinity synt! ! More information about the synth at: www.bastl-instruments.com Before you start: the board solders from both sides and the component goes always above its printed sign so it hides the sign! You should know that there are some differences between some of the versions. SQNCR has more buttons and 3 small leds insteas of the rgb led and therefore different resistors too ...

PWM generator and servo tester using ATtiny45

Hello, in this project I want to show you how to build a PWM generator with a Attiny processor. It is very easy to build and a nice project for starters as also for professionals. You will need some electronic knowledge and some knowledge about Arduino. It wont be to hard, because i already wrote a code for the Attiny, which you can use. This PWM generator also works as servotester, it supports all kinds of ...

6 button RGB controller using Arduino

In this instructable we will learn how to use 6 buttons to control the color of an RGB LED with the use of an Arduino Micro Controller. This is a fun and easy little project that should take you no more then 20 minutes to finish. Step 1: Connecting an RGB LED Before we connect the LED to the breadboard we first need to identify the Anode and Cathodes. If you pick up your LED at a retailer there should be a ...

Serial Call and Response using Arduino

This example demonstrates multi-byte communication from the Arduino board to the computer using a call-and-response (handshaking) method. This sketch sends an ASCII A (byte of value 65) on startup and repeats that until it gets a serial response from the computer. Then it sends three sensor values as single bytes, and waits for another response from the computer. You can use the Arduino serial monitor to vi ...
