Arduino

Question 1

What Is Arduino?

Answer 1

Arduino is an open source programmable circuit board that can be integrated
into a wide variety of makerspace projects both simple and complex. This one
board contains a microcontroller which is able to be programmed to sense and
control objects in the physical world. By responding to sensors and inputs, the
Arduino is able to interact with a large array of outputs such as LEDs, motors
and displays.

Question 2

Two cheaper alternatives to Arduino

Answer 2

Adafruit and Sparkfun for example, sell variations of the Arduino
boards which cost less but still have the same quality of the originals.

Question 3

convert it to digital

Question 18

what is the voltage divider question

Answer 18

Question 19

what Ohm’s law and what equation would it use

Answer 19

The voltage across a resistor is proportional to the current flowing through it, based on its resistance. V=IR

Question 20

what is Kirchhoff’s voltage law

Answer 20

The sum of all voltages around a closed loop equals zero
