UP Board (Intel) UP board 4GB RAM + 64 GB eMMC - UP Board. Microcontroller Basics - Introduction | Homemade Circuit Designs Just for You. One thing is great about microcontroller ICs, these are available almost in all parts of the globe and electronic retailers. Fundamentally microcontroller devices are popularly used in applications involving assessments of the surrounding environment and in similar electronics. You could find these devices being used for displaying a certain parameter, in motor control applications, LED lighting, sensors of various types such tilt sensor, accelerometer, velocity meter, data loggers, temperature controllers, keyboards etc.

The primary understanding regarding microcontrollers could be obtained by referring to AVR Amega32 microcontroller which is so advanced that sometimes it’s called a computer within a chip. This device is assigned to carry out series of commands to form a program. The language of the program that you would be seeing here is C++.

You’ll get to learn this language in greater depths in the course here. The above pins constitute the PORT A. Snap Circuits® | Electronic and Educational Toys.

What is I/O Expander? Input and output pins are very precious resources in small digital projects these days. Popular small micro controllers like the PIC, 8051, SX, BASIC Stamp, etc., may only have 8-to-16 lines of I/O available for use, while we typically have a need to drive LCD displays, LEDs and frequency synthesizers; and read A/D converters, keyboards, shaft encoders and more. Hardware interfacing is the name of the game, and you can never have too much I/O capability on a processor to handle all these tasks. Well, here’s a relatively simple project called the I/O Expander, or IOX for short, that will greatly ease that I/O pin crunch on your current micro controller project. At first it looks like a clone of the common “serial LCD” controller – but when you look under the hood, you’ll see an I/O processor that’s chock full of goodies that we use everyday in our ham applications: serial display driver, frequency counting, A/D conversion, keypad processing and digital potentiometer control.

IOX interfaces peripheral components (LCD, A/D Converter, digital pot, and matrix keypad) to the host processor over a conventional asynchronous serial line. Additionally, the IOX chip has a "frequency counting" capability, providing the host processor with both raw count information and processed frequency values over selectable time gate periods. The IOX chip interfaces to the host processor using a standard asynchronous serial line operating at 2400 baud. Figure 1: Block Diagram of I/O Expander in a System Operation as a Serial LCD Driver.

No stinkin' library needed.... I'm using the term 'blocking' a little loosely here. In Arduino-land... I'm talking about delay(). // ... from the Arduino Blink Sketchvoid loop() { digitalWrite( led, HIGH ); // turn the LED on (HIGH is the voltage level) delay( 1000 ); // wait for a second digitalWrite( led, LOW ); // turn the LED off by making the voltage LOW delay( 1000 ); // wait for a second} "While it is easy to create a blinking LED with the delay() function, and many sketches use short delays for such tasks as switch debouncing, the use of delay() in a sketch has significant drawbacks.

If you're new to Arduino, you might not realize just how badly delays can impact performance. If you need more mileage... structs + PROGMEM can be used to expand this approach to cover dozens of specialized operations without eating-up precious kilobytes.

List of 39 Low Cost Linux Friendly Boards and Products. Dmitry (omgfire), one of my awesome readers, compiled a great tabular list of Linux friendly boards and products that sells for less than $300 US (usually less than $200). This list includes technical details such as the processor, GPU, memory, NAND flash, connectivity, ports, supported Linux distributions… as well as availability and pricing information.

There are currently 39 Linux devices in total. The vast majority are ARM based boards, but he also included 2 x86 products by VIA, but those are relatively pricey ($265 and up). Here’s a summary list with SoCs used, links to blog posts and product pages (if available), as well as price information. Raspberry Pi Board Model B Beaglebone Snowball PDK Lite The list is obviously not exhaustive (this would include hundreds of boards), but this still pretty good. You can download Dmitry’s PDF file that shows side-by-side comparison of 5 devices at a time.

Arduino Buying Guide Let’s face it, there are a a lot of different Arduino boards out there. How do you decide which one you need for your project? With this table, you can not only compare features between all the different Arduino boards we carry, but you can also see why these differences are important.

What is an Arduino? Let’s first talk about what an Arduino really is. All Arduino boards have one thing in common: they are programmed through the Arduino IDE. Why are they different? Some boards are designed to be embedded and have no programming interface (hardware) which you would need to buy separately. 1The miniUSB connector on the Arduino Fio is used for battery charging only. 2The LilyPad Simple Board does have one UART but the pins aren't broken out to pads. *The Arduino Leonardo has the same GPIO pin-count as the other “Uno” style boards but more of the pins play “double duty” as both analog and digital pins, thus the higher numbers. Glossary of Terms: Home energy data logging project. Yesterday I saw that onterio will be increasing the electric bills 46% over the next 5 years as they phase out coal and go renewable.

We don't have coal to phase out but are expecting similar increases in the future. The city recently announced millions in water infrastructure updates and they will be billing that not through property taxes but on water usage. In both cases the more you use the worse the hit will be. So today I decided it's time to get off my *** and get really serious about consumption logging and reduction. We've done pretty good on the electric front but more can be done I'm sure. Water wise we discovered a break in the main on the cities side of the meter so they'll be digging that out and fixing it shortly.

Anyways since I want to do data logging and realtime monitoring of our usage today I ordered an arduino mega microcontroller kit off of ebay. That is a good start to let me know what is going on beyond what my kill a watt can tell me. This should be fun. Spartan 3E Breakout and Development Board. Playground - Java. Arduino. Arduino is an open-source computer hardware and software company, project and user community that designs and manufactures kits for building digital devices and interactive objects that can sense and control the physical world.[1] Arduino boards may be purchased preassembled, or as do-it-yourself kits; at the same time, the hardware design information is available for those who would like to assemble an Arduino from scratch.

The first Arduino was introduced in 2005. The project leaders sought to provide an inexpensive and easy way for hobbyists, students, and professionals to create devices that interact with their environment using sensors and actuators. Common examples for beginner hobbyists include simple robots, thermostats and motion detectors. Adafruit Industries estimated in mid-2011 that over 300,000 official Arduinos had been commercially produced,[3] and in 2013 that 700,000 official boards were in users' hands.[4] History[edit] Hardware[edit] Official boards[edit] Shields[edit] USB + Serial Backpack Kit with 16x2 RGB backlight negative LCD [RGB on Black] ID: 784 - $24.95 : Adafruit Industries. Adding a character display to your project or computer has never been easier with the new Adafruit USB or TTL serial backpack! This custom-designed PCB sits on the back of our 'standard' character LCD (16x2 or 20x4 sized) and does everything you could want: printing text, automatic scrolling, setting the backlight, adjusting contrast, making custom characters, turning on and off the cursor, etc.

It can even handle our RGB backlight LCDs with full 8-bit PWM control of the backlight. That means you can change the background color to anything you want - red, green, blue, pink, white, purple yellow, teal, salmon, chartreuse, or just leave it off for a neutral background. Inside the backpack is an USB-capable AT90USB162 chip that listens for commands both a mini-B USB port and a TTL serial input wire. The USB interface shows up as a COM/serial port on Windows/Mac/Linux. We have a full tutorial, including diagrams, testing instructions, and more! Dangerous Prototypes | A new open source hardware project every month. Arduino and DS18B20 - 1-wire digital thermometer | Ogalik. Finally got this DS18B20 working. Actually three of them. And in two modes. Parasite power mode and main mode. A 4.7K ohm resistor is the key. Starting with the main mode, three wires are needed, as this sensor has three pins. Works with three wires, as seen on the following illustration.

Parasite mode eliminates one wire. Maybe following illustration helps. Of course multiple DS18B20-s or different one wire devices can connected together like so: Here comes the beauty of using digital thermometers. Some words of caution: No pins on DS18B20 should be left unconnected. Software? DS18B20 can also be installed outside. Working with three DS18B20 thermometers for a year now – sometimes those thermometers do not get initialized correctly. Related posts: FTDI Basic Breakout - 5V. Description: This is the newest revision of our FTDI Basic.

We now use a SMD 6-pin header on the bottom, which makes it smaller and more compact. Functionality has remained the same. This is a basic breakout board for the FTDI FT232RL USB to serial IC. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 5V Arduino boards. It can also be used for general serial applications. The pins labeled BLK and GRN correspond to the colored wires on the FTDI cable. This board has TX and RX LEDs that make it a bit better to use over the FTDI cable. This board was designed to decrease the cost of Arduino development and increase ease of use (the auto-reset feature rocks!). One of the nice features of this board is a jumper on the back of the board that allows the board to be configured to either 3.3V or 5V (both power output and IO level). Documents:
