Other Integrate USB programming and communication port.

The EtherTen supports both of these serial communication formats. Wouldn’t it be great if there was an Arduino-compatible board with on-board Ethernet? Can be wired to shields to provide a reset button when the reset button on the Arduino Uno is blocked by the shield.

However we would not normally use the USB port for power.

When the output on pin 13 is high the LED will be turned on. These pins are used to support TWI communications using the Wire library.

I2C and Freetrojics communications: Used to freefronics a reference voltage for the analog inputs. If something goes wrong here then you could very easily damage the ATMega chip.

By default they measure from ground to 5 volts. We use cookies to ensure you have the best experience on our site. GST will be removed from your order if you are ordering from outside Australia. We use the attachInterrupt function to enable interrupts. The Analog to Digital pin mappings are as follow:.

Each of these Analog pins have 10 bits of resolution which translates from 0 to different values. It is also recommended that you do not go above 12V. The on board power regulators are bypassed. The power will go directly into the ATMega micro controller. The 8u2 replaces the FTTI usb chip used on other boards.

They operate at 5V and have a maximum current draw of 40mA. Uses pins D10, D11, D12, D It is fully compatible with the Ethernet library and sketches. Some of these pins have additional functionality. Two tastes that taste great together: To write to the pin we would use digitalWrite with the appropiate digital pin value as shown in the list above.


Integrate USB programming and communication port. The pullup resistors are betwen 2 – 50kOhms and can be enabled via software. Pins 3,5,6,9,10 and fdeetronics Arduino advise against powering the board this way.

Uses pins D4, D11, D12, D However some require additional daughter boards to provide the full All trademarks and trade names are the properties of their respective owners. We use the analogWrite function with a value between and 0 and to control the duty cycle of the output. The power jack is 2.
