- 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)
- Components of a circuit
Battery
Photocell
Potentiometer
LED
Diode
Resistor
Jumper Wires
Capacitor
Electrolytic Capacitor
Integrated Circuit - 555 Timer
Comparator
Momentary Switch
Single Pole Single Throw SPST
Single Pole Double Throw SPDT
Double Pole Double Throw DPDT
Solid State Relay SSR
- 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
