GMU:Devices of Perception/Paul Haas

BASICS

• DC Direct Current Gleichstrom
• AC Alternate Current Wechselstrom

Ohm's law Ohmsches Gesetz

• R = U/I U = R*I I = U/R

• R - Resistance, Widerstand Ohm
• U - Voltage, Spannung V
• I - Amperage, Stromstärke A

Capacitor/Condensor, Kondensator

• used to store energy electrostatically in an electric field
• Speichern von elektrischer Ladung und damit zusammenhängender Energie

Electrolytic Capacitor, Elektrolyt-Kondensator

• same function as the usual capacitor, only use with DC
• Anode and Kathode → polarised

• F - Farad - electric capacity, elektrische Kapazität
• Müh - micro, mikro

• 0,01MühF (103)
• 1 MühF
• 4,7 MühF
• 47 MühF
• 220 MühF

Resistors and ist color Codes, Widerstände und ihre Farbcodes

• brown black red 1 K Ohm
• brown black orange 10 K Ohm
• brown black yellow 100 K Ohm
• brown black green 1 M Ohm

LED

LED - Light Emitting Diode ↔ (regular) Diode -always connected to a resistor as it does not need as much current as the other parts of a circle → resistor with 1 K Ohm (brown black red)

Examples for components of a circuit

From left to right: Battery, Potentiometer, LED, Capacitor, Cable, Electrolytic Capacitor, 555-Timer, TIP 122, Motor, Double Pole-Double Throw-Relay, Terminal

Switches

Momentary Switch

Double Pole Double Throw

• Double Pole Double Throw DPDT
  
• Single Pole Single Throw SPST
• Single Pole Double Throw SPDT

two different circuits

• daisy chain - Reihenschaltung
• parallel chain - Parallelschaltung

ASTABLE 555

turns on and off constantly, square wave like

MONOSTABLE 555

trigger, decide when on or off
