The Arduino Shield Webinar teaches you to create your own self-made Arduino Shields in no time! Free of charge!

This webinar is for those of you who..

  • have great ideas that you want to get out of your head and into the physical world
  • have learned the basics of Arduino and want to take your skills to the next level
  • knows little or lots of theory, but lacks the practical experience of building real circuits
  • dreams about impressing your friends with that awesome circuit you have been thinking about for soooo long

…you can simply copy the methods I teach in this free webinar and create whatever Arduino Shield you want.

ENC28J60_module

voltsandbytes writes:

Probably, some of you have tried buying cool but cheap products from Ebay. Like some of you, I also have bought items from Ebay several times already. One of the items that I got from Ebay is a small ENC28J60 based ethernet module.

As you can see from the image above, the ENC28J60 module is very small. The PCB is more or less one-inch square which is almost as small as the included ethernet jack.

Audio-Shield5

This Voice shield can be useful to integrate voice messages in alarm systems, to implement generic I/O controls in home automation or even in home security applications: something like playing an alert when a person or a vehicle approaches any given protected area. The use cases are many and limited only by your imagination!

While this shield can operate stand-alone, it can be better managed through and SPI interface: by connecting this with Arduino it can take control of the speech synthesis.

Here’s a tutorial on interfacing MAX7219 LED driver chip to Netduino platform for driving 8 digits of seven segment LED displays. The .NET Micro FramWork provides a SPI class that is used to send display data to the MAX7219 chip through a SPI serial interface.

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.

To control the car used Android-device with a built-in accelerometer. Tilt forward – car goes forward, tilt to the left – car turns to the left, tilt back – car goes back. Speed of movement or rotation depends on how much you tilt the device. Sensitivity and value of the tilt set in the configuration Android-apps. Also are provided a normal way to control: the buttons on the screen. In addition to all I implemented the touch control. Total 3 ways to control the RC Car.

When collecting data from a sensor, it wonʼt be very long before you need to calculate some statistics on that data such as the mean and standard deviation. A touch sensor is a good example. Its data may not be very stable and an average needs to be calculated in order to determine a valid touch. Standard deviation is another useful measurement in helping determine the quality of the data gathered.

Because of the very limited memory in microcontrollers, the luxury of storing large data sets is not possible. This article describes a means to collect such a dataset with a very small storage footprint.

The TinyCircuits TinyDuino is an Arduino compatible board in an ultra compact package. Imagine the possibilities of having the full power of an Arduino Uno in a size less than a quarter!

Each module in the TinyDuino family has been optimized to include only the core circuits for it’s specific function to keep the size as low as possible at the best possible price. The main TinyDuino processor board includes the core processor circuitry, however the USB and DC power regulators have been offloaded to TinyShields. So for example, if you have a project that doesn’t need support for DC power above 5 volts, you don’t need to include the Power TinyShield, saving you money and keep the overall size down. Or if you don’t need USB on your project, you’d only need one USB TinyShield that you’d use to program your boards.

by Publitek European Editors:

Building an Arduino system that harvests energy from the environment provides a significant amount of freedom from wiring, but requires some close attention to the system design. Using power from the environment and wireless links frees up the board from any wiring and gives tremendous flexibility for placing the equipment.

Arduino is an open-source electronics prototyping platform that is specifically optimized for the hobbyist building systems that receive input from sensors. This is particularly appropriate for an energy harvesting design so that sensors can be placed in the right location without having to worry about power and signal wires.
