LAB 1: ELECTRICITY & COMPONENTS Goals - Basic understanding of components - Read a simple circuit diagram - Translate from simple circuit diagram to breadboard - Learn to use a multimeter Differences between Software and Hardware - Safety - Mistakes can break things - Work in modules, break large problems in to small - Debugging with multimeter, not println() Electronics > Electricity - Voltage (110, 220, 5, 9, 12, Volts) . Check with multimeter, wall device . Relative, ground - Current (Amps) - AC/DC (Hertz) - Resistance - Conductance Basic Components (show different types, symbols) - Resistor . Measued in Ohms, . Values in painted bands . Check with multimeter, dashboard widget - Capacitor . measured in Farads, usually microFarads, picoFarads - Diode, Light emitting diode Circuit - Drawing to abstraction with light example Kit - Wire (Solid, stranded, braided)(Color coding) - Breadboard - Wire clippers - Multimeter Exercises 1. Resistor Worksheet (with partner) 2. LEDs Circuits (with partner) Reading to complete for next class - "Anatomy of a Flashlight" handout - Physical Computing (pp. 3 - 48) - 555 Timer handout - Familiarize yourself with all Net references (from syllabus)
