Glossary

• Alternating current (AC) - current that changes direction, your typical power outlet;

• Direct Current (DC) - one way current used in most electronics;

• Volts (v) - literally “pressure” of power;

• Current (amperage) (I) - literally “amount” of power;

• Resistance (Ohm) (r) - the relation property between voltage and current;

Components

Resistor

a piece of tubular material reisting n ohms. Resistance is measured in colour coded system of multiplied values and tolerance (accuracy).

Light-Emitting Diode (LED)

Literally a tiny lightbulb.

All diodes have two legs:

• Anode (+) - the longer one;
• Cathode (-) - the shorter one, sometimes has flat bit;

Switches

• Toggle switch - literally On/Off

Equations

Calculate resustance necessary for component

R = (Power soource voltage - component voltage) / components amperage;

Tools

• Small metal clamps - for fast prototyping, tetsing, holding things together;
• Neeldenose pliers - just a do-it-all tool that does nothing well. I looked for plier, wire stripping, cutting and crimping together. Actually does all I need;
• Wire cutter - specific tool to remove insulation from wires;
• Bread board - a basic board to hold prototyping components;
• Electronic insulation tape - a consumable to isolate different wires;
• Multimeter - most important tool to measure different values;
