This is a simple project of Android Bluetooth Car with Bluetooth control. This project is open source and multiplatform: Arduino (Processing), STM32, MSP430, PIC, AVR, FEZ Panda II (.NET Micro Framework) and may be even В Raspberry Pi.
The project itself is not complex less than familiar with some concepts such as I2C and SPI, In fact, I decided to use a shield SD Card to write my data to an SD card 64GB, more than sufficient for some line of log in a text file, and an RTC to maintain the time of acquisition of the log.
A few months ago I was looking into how to use Fbus with a Nokia phone but didn’t have much luck and instead just wired up the keypad. I decided to revisit Fbus and this time happened to find some AVR code which could send/receive SMS’s so now I’m able to send an SMS using the Arduino and I’ll explain how we do this.

One of the modules that are used to work with high voltages, is the Relay. On the front it has three ports: NO, COM and NC. It works like a regular switch: when triggered, it closes the connection with the NO (Normally Opened) and opens the one with the NC (Normally Closed). For example, if we connect two wires, one on the NO and one on the COM, they’re not connected until we give the .on() command to the relay. If we put them on COM and NC, they are always connected until the .on() command is given.
Statistics on the Arduino (also Pic or any microcontroller) - When collecting any data on the Arduino, it won’t be very long before you need to calculate some statistics on that data. While statistics can be a ...
Sure, the physical build itself looks great, but it's what [Michael] did with the firmware that impresses us the most. He's using an Arduino Mega to drive the 7x7x7 cube and manages to squeeze out what he calls 142 frames per second with the setup.
In this video, Alessandro Contini and Alberto Massa not just walk you through the process of making a Synth, but actually take you to other videos that explain the first steps to even set the kit to work. What i like about this work is that is truly expressing the capacity to build on other people works.
Having two or more Arduinos be able to communicate with each other wirelessly over a distance opens lots of possibilities:
Remote sensors for temperature, pressure, alarms, much moreRobot control and monitoring from 50 feet to 2000 feet distancesRemote control and monitoring of nearby or neighborhood buildingsAutonomous vehicles of all kinds
A visual output always adds value to any project. In this third day tutorial, we are going to display some numeric, alphabetic as well as two symbolic characters on a 4-digit seven segment LED module. The way we are interfacing the seven segments LEDs is known as multiplexing, which allows to save some I/O pins of Netduino as compared to driving them individually. The seven segment LEDs are resource and power hungry, but we are going to do this experiment just to get our feet wet in the microcontroller or embedded world and to understand the basics of a seven segments LED displays.
Ok, the Arduino Esplora has been out about 3 weeks. It's time we had some cool software for it and what better than a fun game. Today I publish a game for running on the Esplora with an Adafruit 1.8" display.
