25 Questions

1.
Electrical machines which convert electrical power into mechanical power from DC electricity

2.
an inexpensive single-board computer designed primarily for use in schools

3. I ( I = V/R)

4.
allows us to build complicated circuits without the need for soldering

5. What are the 2 basic categories of conductivity?

6. void setup() {
// put your setup code here, to run once:
}

The setup() function is called when a sketch starts. Use it to initialize variables, pin modes, start using libraries, etc. The setup function will only run once, after each powerup or reset of the board.

7.
small brain of the computer

8.
(Light emitting diode) emits light only when current/ a large enough voltage is applied across its positive and neg electrodes, passing does not light up when current is absent (The LED is a type of 'diode', which is like a one-way street for current flow. Current only flows in one direction, and is blocked in the other direction.Usually LEDs only work in one direction.)

9.
Arduino is used to describe the microcontroller board and also programming language \ environment

10.
An electro magnetical device that converts electrical energy into kinetic (physical) energy on demand.

11. alternating current power source( represented with a circle with a wavy line inside, wavy line inside represents the sine wave that an alternating current source provides)

12.
resist the flow of electricity, lower the voltage

13. A motor that rotates a predefined angle with every electrical impulse.

14.
The 'brain' of the robot. The microcontroller contains the robot's program and processes all signals received from both human operators and on board sensor systems. It also manages power allocation on board the robot and directly controls the motors.

15.
lets current through momentarily when it is pushed

16.
they are used to make connections between the arduino and the breadboard

17. a programming construct that repeats a group of commands.

18.
direct current power source

19.
Any motor that is modified to give feedback concerning the motor's speed, direction of rotation, and number of revolutions. Usually gives you precise control over a range of motion

20.
Uses reflected sound waves to measure distance between the sensor and any objects in its path.

21.
the voltage in each branch is the same, If a component is removed from the circuit the other components will continue to function because it is still a closed circuit.they both receive power from the battery independently.

22.
A switch that can provide variable motion control. It can vary the resistance within the switch, which affects both the current and voltage flowing out of the switch.

23.
A circuit board for wiring temporary circuits, usually used for prototypes or laboratory work.

24.
A way of representing information using only two options.

25.
A Piezo Sounder is a Piezoelectric speaker and is used to convert electrical signals into sound just like a speaker.
