There is a small power supply on the board for generating 3. 3V @ 250mA. We don`t use the `built in` 3. 3v regulator on the Arduino because its only guaranteed up to 50mA and some SD card need a lot of power when writing. This supply is nice and steady, we....

To do this, first, we must make the appropriate physical connections from the arduino board to the LCD. Then after, we must write the code so that whatever text we want displayed comes up on the LCD. LCDs are pretty much the standard now in order to display....

For example, once the motion sensor picks up motion, we can program the arduino to turn on an LED, turn on a motor so that it spins, sound a buzzer off, etc. In this circuit we are doing here, for simplicity, we will simply turn on an LED once the motion....

BC547 transistor. Max operating current is 100 mA while max voltage is 65 volts. With the transistorlabelfacing the reader, the three legs from left to right are collector, base and emitter. Note: I destroyed one BC547 transistor while setting this up. I....

Implementation of CAN for use in aircraft. The protocol is called CAN-FIX and is a part of the MakerPlane Open Source Airplane project. You can get more information on CAN-FIX here. The idea for this project is to build an Arduino shield that will let it....

This is the next part in our learning Arduino series, and this time we ll be learning about and using Arrays to make a little Christmas tree ornament with various flashing sequences. This would be an ideal project to keep the kids occupied if you`d like to....

If you want to improve your Arduino programming, creating a traffic light controller is great practice....

The L298N driver module contains the ST` L298N chip, ususlly used to drive two 3-30V DC motor, there is a 5V output interface, power for 5V single-chip circuitry, support 3. 3VMCU control. With it, you can control the DC motor easily. You can get the diagram....

One of the simplest ways to get a motor to turn in both directions is by using a double-pole, double-throw (DPDT) relay. Along with the relay, this hookup requires two transistors and two Stamp pins, one for on/off control and the other for direction....

The strategy is to get the circuit going in stages, testing each part as you go. Once everything is wired correctly and can be either controlled or read by the computer correctly, then you can write the main program with confidence that all the pieces are....

This is a complete Arduino Uno-compatible standalone system, and will be fully assembled, tested, and programmed before shipping. You may choose one of several TC4 applications to be pre-programmed into the board. If you would like to use the TC4 system, but....

I experienced faulty DS18B20 reads on my tank thermometers, probably due to my heatshrink/silicone waterproofing method. It gave me a chance to improve my code to make the controller more tolerant of bad reads, but my tank thermometers have now been replaced....

The term Arduino actually refers to a system of components that include the board, the microcontroller, the boot-loader, and the programming environment. It is a system designed to `protect` the user from a lot of the complication that is part of....

The objective of this project is to build an Arduino voice shield to empower thousands of voice related applications! All this mostly thanks to an integrated ISD1790PY chip. This particular voice/ TTS feature can be useful to integrate voice messages in....

A wood table with many holes with different diameters that house the optical fibers. The size of the ceiling lamp (90 cmx 60 cm) did not allow me to use a single bundle of fibers and this is the reason of the two beams I used, each of which comes with a LEDs....

The system consists of two parts: the Arduino board that detects the led pulses and sends the data via the XBee module, and a PC that recive the data through a USB/Xbee module and processes the data with LabVIEW so you can prepare and study the consumption....

The idea behind this post is to bring together some robot designs and trasform them in a new device with new hardware and standard software (arduino of course) and so easier to use. These robots have three things in common: a mechanical structure, the....

Using an ATmega 2560 and therefore the heart of Arduino, we have developed a universal remote control with GSM. This allows to control 2IN/2OUT, DTMF key, gate control and GSM thermostat activated remotely. The remote control is easier, thanks to the....

A simple project to use an Arduino to rotate a GH-2 on a fluid head by set degrees to take 360 panos. The control of the motor is simple. Lots of motor DIY out there. What I need help with is how to wire the Arduino to the GH-2 shutter release. I`m aware the....

The schematic for this project really only consists of adding a single 5mm LED to one digital output port on the Arduino. The picture below should be fairly self explanatory for how to do it. The main parts in the schematic are the Arduino Uno, 5mm LED and....

The Flash-based program memory is where the program sketch is stored after an upload. The SRAM act as the main memory where program variables are temporarily stored as the sketch executes. The system clock synchronizes the internal operation of the CPU and....

The idea is that the infra-red light is reflected by the disc, except by the dark red line. The reflected light is received by the sensor and this way the Arduino can keep track of the number of revolutions. Note that the infra-red sensor is sensitive to a....

This Arduino sketch is useful for rescuing ATtiny microcontrollers rendered useless by incorrect fuse settings. It does this by putting the bricked tiny into high-voltage serial programming mode and writingthe fuses to safe values. The Arduino is connected....

The TV-B-Gone is a tiny infrared remote that can turn off almost any TV. A while ago, I ported the TV-B-Gone software to the Arduino; for details on the port and how it works see my previous post on the Arduino TV-B-Gone. Mitch Altman, the inventor of the....

Starting from today I will try to post interesting Arduino projects from around the web. I am novice in this domain but I am giving my best to fully understant it. I must say from the begining that the projects are not developed by me and I will link the....
