Engineering 111 Final Review Questions with Correct AnswersMain difference between Arduino boards Correct Answer-Main micro controllers can differ
How voltage is controlled Correct Answer-Controlled by 2 regulators that cannot be changed
Input Voltage Correct Answer-Input voltage (recommended) 7-12 V
Input voltage (limits) 6-20
If voltage limits are exceeded the board may either not function correctly
or be damaged
ESDS Correct Answer-Electro-Static Discharge Strap
Wires used in the arduino project Correct Answer-22 AWG insulated wire
Arduino Correct Answer-Open source physical computing platform based on a simple input/output board and an integrated development environment that implements the processing language
IDE Correct Answer-Integrated development environment Physical computing Correct Answer-Using electronic sensors, actuators and software running on a micro controller to prototype new interactive designs
Arduino Language Correct Answer-C/C+
Types of Electrical diagrams Correct Answer-- Circuit diagram
- Block diagram
- Layout
Circuit diagram Correct Answer-Shows electrical components and power and signal connectors AKA wiring/electrical diagram, electrical/electric diagram
Block Diagram Correct Answer-Doesn't show internal components or connections. Only principle blocks/functions connected by lines shown
Layout Correct Answer-depicts the actual arrangement of the components and connections
Voltage source Correct Answer-Pressure
V (Volts)
Resistor Correct Answer-Friction Ohm Wires Correct Answer-______________________
Power Correct Answer-W (Watt)
Current, I Correct Answer-Flow Rate
A (ampere)
Measure voltage Correct Answer-voltmeter/multimeter, potentiometer, oscilloscope
Measure current Correct Answer-ammeter, multimeter
measure power Correct Answer-wattmeter
measure resistance Correct Answer-Ohmmeter
Ohm's Law Correct Answer-V=IR
KCL Correct Answer-Kirchhoff's Current Law - The sum of the currents
leaving a surface is zero
KVL Correct Answer-Kirchhoff's Voltage Law - The sum of the voltages around a loop is zero. Serial combination of resistors Correct Answer-Req=R1+R2+R3+...+Rn
Same current goes through each resistor Total voltage drops proportionally
Parallel combination of resistors Correct Answer-1/Req=(1/R1)+(1/R2)+(1/R3)+...+(1/Rn)
Total current divides inversely
Same voltage drop occurs across each resistor
Diodes Correct Answer-Electrical one-way valve, like a flapper valve or a dam
Current flows forward in ON state and no current in the OFF state Made from semiconductors
BJT Correct Answer-Bipolar junction transistor - current controlled devices Made of a base, collector and emitter
FET Correct Answer-Field effect transistor - voltage controlled devices Made of gat, drain and source
Photo resistor Correct Answer-Resistor whose resistance decreases with increasing incident light intensity
