integrated circuit No keyboard No printer No disk drive Thursday, September 15, 2011
USB cable BBB Arduino BUB can communicate (interface) with a computer Thursday, September 15, 2011
able to read: sensors voltages (analog signals) serial information (digital signals) able to output: voltages (analog signals) serial information (digital signals) Thursday, September 15, 2011
able to read (IN): sensors voltages (analog signals) serial information (digital signals) active sensors passive sensors data from laptop able to output (OUT): voltages (using PWM function) serial information (digital signals) motors lights simple LCDs data to laptop Thursday, September 15, 2011
resistors resist the flow of current - help to drop voltage Thursday, September 15, 2011
resistor chart
potentiometers ( pots ) your classic volume control knob is a great example. turn one way - more the other way - less (A variable resistor) Thursday, September 15, 2011
capacitors capacitors can hold an electrical charge - albeit briefly Thursday, September 15, 2011
LED (light emitting diode) LEDs are everywhere, from your cell phone to your night light. Thursday, September 15, 2011
diode lets current travel in only one direction - like a valve Thursday, September 15, 2011
semiconductor a generic package for many items. we will use a voltage regulator today. Thursday, September 15, 2011
Tethering?
momentary switch push button - on, otherwise they are off. enough said. Thursday, September 15, 2011
terminal blocks an easy way to attach wires to a project Thursday, September 15, 2011
Header Pins
integrated circuit (IC chip) another generic package. our Arduino s Atmel processor is contained in one of these. Thursday, September 15, 2011
IC chips on static bag IC Chips are sometimes sensitive to static. keep your chips in bag until you use them. try to ground yourself before using them. Paul says not to worry about it. Thursday, September 15, 2011
socket allow you to change IC chips without having to de-solder and solder in a new chip. handy for students who burn out a chip. Thursday, September 15, 2011
