How to spend your time

If we tried to debate whether or not life is unfair, we’d probably come to a separate realization:

 Spending too much time focused on others’ strengths leaves us feeling weak. Focusing on our own strengths is what, in fact, makes us strong.

To spend more money, you have to have more money, but time is fixed and we all have the same amount to spare. How we choose to spend it can make a significant difference on the impact we have in our careers or in the world. More than anything else lately, I’ve become obsessed with how to spend my time. If I waste my money, I can always make more of it, but if I waste my time, there’s no getting it back. One big thing I’ve learned these past few months is that we have more control than we think over how we spend our time.

Arduino Due

 

Description: The Due is Arduino’s first ARM-based Arduino development board. This board is based on a powerful 32bit CortexM3 ARM microcontroller made programmable through the familiar Arduino IDE. It increases the computing power available to Arduino users keeping the language as compatible as possible so that many programs will be migrated in a matter of minutes!
The Arduino Due has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), an 84 MHz clock, a USB-OTG capable connection, 2 DAC (digital to analog), 2 TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button. There are also some cool features like DACs, Audio, DMA , an experimental multi tasking library and more.
To compile code for the ARM processor, you’ll need the latest version of the Arduino IDE: v1.5 (After a period of testing and debugging this will replace the 1.0.1 IDE altogether)
Because of the limitations of system voltage imposed by the Atmel SAM3X8E, Arduino shields that are based on the 5v models won’t work properly. All the shields that fully implement the Arduino R3 layout are compatible straight away (like the Arduino WiFi shield and Ethernet Shield) but other shields might not be compatible. Be careful when you’re plugging stuff in!

Features:

• Microcontroller: AT91SAM3X8E
• Operating Voltage: 3.3V
• Recommended Input Voltage: 7-12V
• Min-Max Input Voltage: 6-20V
• Digital I/O Pins: 54 (of which 12 provide PWM output)
• Analog Input Pins: 12
• Analog Outputs Pins: 2
• Total DC Output Current on all I/O lines: 130 mA
• DC Current for 3.3V Pin: 800 mA
• DC Current for 5V Pin: 800 mA
• Flash Memory: 512 KB all available for the user applications
• SRAM: 96 KB (two banks: 64KB and 32KB)
• Clock Speed: 84 MHz

Arduino Leonardo 

 

Description: Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux).
The Leonardo is Arduino’s first development board to use one microcontroller with built-in USB. Using the ATmega32U4 as its sole microcontroller allows it to be cheaper and simpler. Also, because the 32U4 is handling the USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, and more using the USB-HID protocol!
It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.


Features:

• ATmega32u4 Microcontroller
• Input Voltage: 7-12V
• 20 Digital I/O Pins
• 7 PWM Channels
• 12 ADCs
• 16MHz Clock Speed
• 32 KB Flash Memory

Arduino Mega R3

 

Description: Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux).
The Arduino Mega is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila.
The Mega 2560 R3 also adds SDA and SCL pins next to the AREF. In addition, there are two new pins placed near the RESET pin. One is the IOREF that allow the shields to adapt to the voltage provided from the board. The other is a not connected and is reserved for future purposes. The Mega 2560 R3 works with all existing shields but can adapt to new shields which use these additional pins.

Features:

• ATmega2560 microcontroller
• Input voltage - 7-12V
• 54 Digital I/O Pins (14 PWM outputs)
• 16 Analog Inputs
• 256k Flash Memory
• 16Mhz Clock Speed

Arduino Uno  R3

 

 

Description: This is the new Arduino Uno R3. In addition to all the features of the previous board, the Uno now uses an ATmega16U2 instead of the 8U2 found on the Uno (or the FTDI found on previous generations). This allows for faster transfer rates and more memory. No drivers needed for Linux or Mac (inf file for Windows is needed and included in the Arduino IDE), and the ability to have the Uno show up as a keyboard, mouse, joystick, etc.

Note: The Arduino Uno R3 requires the Arduino 1.0 drivers folder in order to install properly on some computers. We have tested and confirmed that the R3 can be programmed in older versions of the IDE. However, the first time using the R3 on a new computer, you will need to have Arduino 1.0 installed on that machine. If you are interested in reading more about the changes to the IDE, check out the official Arduino 1.0 Release notes!
