single button for led on/off

        single button for led on/off

One micro button for turn on the LED and turn OFF the LED. it is very simple and the code.

1. atmega 16 microcontroller
2. micro button
3. 3v LED
4. 5v supply

softwares

1. atmel studio
2. extreme burner

This technic was used in most of all electronics devices. so it was usefull for all electronics students and starters.  when we press a button tle led was turn one then again pressthe button LED turn off. In this project I used led. But it is work all electronic output devices like motor, home lights,and more.

Tt is very simple code................... 

TEENSY BOARD

The Teensy is a breadboard-friendly development board with loads of features in a, well, teensy package. The Teensy 3.1 brings a 32 bit ARM Cortex microprocessor into the mix so you can do some serious number crunching.
The Teensy 3.1 comes pre-flashed with a bootloader so you can program it using the on-board USB connection: No external programmer needed! You can program for the Teensy in your favorite program editor using C or you can install the Teensyduino add-on for the Arduino IDE and write Arduino sketches for Teensy!

The processor on the Teensy also has access to the USB and can emulate any kind of USB device you need it to be, making it great for USB-MIDI and other HID projects. The 32 bit processor brings a few other features to the table as well, such as multiple channels of Direct Memory Access, several high-resolution ADCs and even an I2S digital audio interface! There are also 4 separate interval timers plus a delay timer! Oh yeah, and all pins have interrupt capability. Also, it can provide system voltage of 3.3V to other devices at up to 100mA.
All of this functionality is jammed into a 1.4 x 0.7 inch board with all headers on a 0.1" grid so you can slap in on a breadboard and get to work! On top of everything else the Teensy has been gifted with more RAM (64K, thats 4x more than the Teensy 3.0) and 256kb of flash memory! The Teensy 3.1 now has 5V tolerance on its digital inputs however all analog-only pins are still 3.3V only.

Note: This does not come with a USB cable, please check below for an appropriate one.
Dimensions: 1.4 x 0.7" (~35 x 18 mm)
Features:

• 32 bit ARM Cortex-M4 72 MHz CPU (M4 = DSP extensions)
• 256K Flash Memory, 64K RAM, 2K EEPROM
• 21 High Resolution Analog Inputs (13 bits usable, 16 bit hardware)
• 34 Digital I/O Pins (5V tolerance on Digital Inputs)
• 12 PWM outputs
• 7 Timers for intervals/delays, separate from PWM
• USB with dedicated DMA memory transfers
• 3 UARTs (serial ports)
• SPI, I2C, I2S,CAN Bus, IR modulator
• I2S (for high quality audio interface)
• Real Time Clock (with user-added 32.768 crystal and battery)
• 16 DMA channels (separate from USB)
• Touch Sensor Inputs

RASPBERY PI

    Raspberry pi is  the computer board or mini computer. raspberry pi board developed and marketing by broadcomm inc. raspberry pi has HDMI, USB, ETHERNET NET port and GPIO pins. GPIO pins used to connect binary world and real world. we can connect with LED, MOTOR OR MOTOR DRIVER, 7 segment led, relay, and etc. Raspberry pi has running with arm 7 processor and 1gb RAM and VIDEOCORE IV graphics and embedded OS. python and visual studio any many   tools to  write programs. Raspberry pi had unlimited possibility.

SAMSUNG SOC

     The Samsung Exynos Octa 7420 has a highperforming CPU with a maximum clock speed of 2,100.00 MHz. It has 8 core(s), resulting inextremely efficient multi-tasking when compared to dual core processors.

     This processor is based on the Reduced Instruction Set Computing (RISC) design strategy enabling instructions to execute faster, as opposed to the Complex Instruction Set Computing (CISC) design strategy, which is generally slower at executing due to lengthy instructions.
