The boxes â supply segment groups â can be compared based on a weighted average Brent break-even price to define their relative competitiveness. Rystad Energy estimates that oil sands and the Arctic are the most expensive supply segments with an average breakeven of ~80 USD/bbl. Within offshore, shelf has the lowest average break-even price at ~60 USD/bbl, only marginally higher than Onshore Row.â.
The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button.
Pins (5V, 3.3V, GND, Analog, Digital, PWM, AREF) 1  GND (3): Short for âGroundâ. There are several GND pins on the Arduino, any of which can be used to ground your circuit. 2  5V (4) & 3.3V (5): As you might guess, the 5V pin supplies 5 volts of power, and the 3.3V pin supplies 3.3 volts of power.
