relatively complex inside: screen (CRT) disk drive backup battery power supply connectors for: keyboard printer n more! Wednesday, January 4, 2012
integrated circuit a microcontroller is a small computer on a single integrated circuit consisting of a relatively simple CPU combined with support functions Wednesday, January 4, 2012
integrated circuit No keyboard No printer No disk drive Wednesday, January 4, 2012
USB cable BBB Arduino BUB can communicate (interface) with a computer Wednesday, January 4, 2012
able to read: sensors voltages (analog signals) serial information (digital signals) able to output: voltages (analog signals) serial information (digital signals) Wednesday, January 4, 2012
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 Wednesday, January 4, 2012
resistors resist the flow of current - help to drop voltage Wednesday, January 4, 2012
resistor chart
potentiometers ( pots ) your classic volume control knob is a great example. turn one way - more the other way - less (A variable resistor) Wednesday, January 4, 2012
capacitors capacitors can hold an electrical charge - albeit briefly Wednesday, January 4, 2012
LED (light emitting diode) LEDs are everywhere, from your cell phone to your night light. Wednesday, January 4, 2012
diode lets current travel in only one direction - like a valve Wednesday, January 4, 2012
semiconductor a generic package for many items. we will use a voltage regulator today. Wednesday, January 4, 2012
Tethering?
momentary switch push button - on, otherwise they are off. enough said. Wednesday, January 4, 2012
terminal blocks an easy way to attach wires to a project Wednesday, January 4, 2012
Header Pins
integrated circuit (IC chip) another generic package. our Arduino s Atmel processor is contained in one of these. Wednesday, January 4, 2012
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. Wednesday, January 4, 2012
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. Wednesday, January 4, 2012
inductor
breadboard allows us to mock up circuits Wednesday, January 4, 2012
