FM430 – A MSP430 and TEA5767 Project that lets you listen to clear digital FM

One fine day while i was rummaging through the part bin, I found an old project that probably was never completed ! FM Radio ! I tried to make one when i was in 7th grade, waiting at the counter of a dingy electronics repair shop for anyone to pay attention to the parts list gathered over the internet ( Dial up days ! ). At that time, i just jotted down all i could from the internet and went straight to the ...

TiDiGino Contest using arduino

The project TiDiGino We developed a new GSM remote control called TiDiGino. The name recalls the initials (TDGxx) of our previous GSM remote control and is also based on the Arduino project. All the details of this circuit can be found below, but no the sketch, because this is your assignment. The contestYou have to write the firmware for this project.  The device must perform all the functions of the past ...

Control Ikea Dioder LED Strip with Arduino + 16X PWM LED Fader Board using arduino

We're going to show how to wire up and control an Ikea DIODER LED strip with an arduino, using a 16X PWM LED Fader board as an intermediary. The 16X PWM board is basically a bunch of mosfets under PWM control (switches that turn on and off really fast) that can be used to mix different levels of the main three DIODER colors: red, green and blue. The PWM board also has a bunch of fading and sequencing comman ...

Secret Knock Final using arduino

Secret Knock Description - My final project is a door lock that listens for your personalized knock. The lock uses an arduino board and a piezo speaker and will not unlock the door unless the specific pattern is used as a knock. Arduino Program - /* Detects patterns of knocks and triggers a motor to unlock it if the pattern is correct. By Steve Hoefer http://grathio.com Version 0.1.09.20.09 Licensed under C ...

Nokia 5110 graphics tutorial

Step 1: Connections First let's connect the Nokia 5110 display. Remember that the LCD runs on 3.3V and although some people have connected it to 5V, it has worked but gave some weird effects, so I suggest connecting to the 3.3V output of the arduino. Next, the LIGHT pin on the LCD. It is the one pin which is controlling whether backlight is on or off. It will be on if the pin is connected through ground and ...

Thermocouple Sensor 1.0 using arduino

Overview Jump to the Table of Contents This is a simple board for measuring temperature. It uses an AD595 chip to make thermocouple measurements easy. The AD595 amplifies the thermocouple signal and conditions it for easy use. Thermocouples are great due to their linearity over a large range, and their high temperature capability (up to 1300C!) You'll need a soldering toolkit to do most of this. Read our El ...

Arduino Vacuum Gauge Display

Initial testing. Ignore the humidity sensor, that was for something else. The vacuum gauge outputs 0-10VDC. This had to be changed to a 0-5VDC range using a potential divider so it was compatible with the Arduino. Initial build used a 10k pot in place of a vacuum gauge to make it simpler. The OLED screen simply plugs in over the arduino which made for a nice compact board. A custom pcb would've looked nicer ...

Display Live Txts on Costume at Party w/ Scrolling LED Belt Buckle using arduino

This project shows how to send SMS text messages to a cheap scrolling LED display via an Android app and arduino with USB host shield. The project was originally inspired by a friend wanting to make a "sexting themed" costume, with a scrolling LED display of live texts sent from people at the party. We found a $13 LED belt buckle online, which looked cool, but only had a few buttons to manually enter in mes ...

Arduino: measuring the Earth’s magnetic field with the magnetometer HMC5883L using arduino

The HMC5883L magnetometer This component (a small chip) HMC5883L, produced by Honeywell, bases its operation on  AMR (Anisotropic Magnetoresistive) technology and allows you to be able to measure both the direction and the magnitude of the earth’s magnetic field. This magnetometer HMC5883L has within 3 magneto-resistive sensors arranged on three perpendicular axes (the Cartesian axes x, y and z). Here you c ...

Universal soldering controller

The intention was to build the most universal soldering controller I can think of. It can drive any low voltage (upto 24V) iron with thermocouple or resistive sensor, in series with the heater, or separate. Here is a short list of features: - power: 9-28V, AC or DC - 2 separate heater control channels - 2 independent sensor inputs - current source on any sensor input 3uA - 12mA, wuth 2 bands (x1, x16) and 2 ...

Nunchuk-controlled Helicopter using arduino

Welcome to my 3rd Instructable everyone ! Today we're going to build a 'device' to control a mini-sized helicopter with a Wii Nunchuk. The helicopter that we're using is a cheap (26$) 3-channel (yaw, throttle, pitch) helicopter that I bought a 1 month back from Dealextreme.com . I can say that it is a VERY durable heli : I have crashed more thant 100 times and it's still working ! It is not radio-controlled ...
