Report for the Second Presentation.

We put in a the house 12 white light LEDs (5 outside, 7 inside) to illuminate the house and connect four fan on the breadboard with a pressure sensors, when you applies pressure on any floor the LED and the fan (if the room have) turn on, also we made a volt-ammeter on the breadboard, we try different scales for find the best to our domotic house.

We are satisfied with the result because we accomplished what was thought from the beginning to do for this presentation, and we did a little more.

We implemented all the activities what was thought for do on this presentation, we finish the model of the house, and implement minimum two devices.

We still need to finish the program for manipulate all the devices of our house with a computer and put the circuit of the parallel port in the house, finish the portfolio of evidences and put the Daniell Cell in the house for the emergency system.

BIKE ASSEMBLY

Part	Drescription	Image
Bottom Bracket	The bearing system that the pedals (and cranks) rotate around. Contains a spindle to which the crankset is attached and the bearings themselves. There is a bearing surface on the spindle, and ones on the cups that thread into the frame.
Chain	A system of interlinking pins, plates and rollers that transmits power from the front sprocket(s) to the rear sprocket(s)
Clips	Clipless pedals use a cleat which is bolted to the bottom of the shoe.
Cog/Cogset	The set of rear sprockets that attaches to the hub on the rear wheel
Cranks	The two cranks, one on each side and usually mounted 180° apart, connect the bottom bracket axle to the pedals.
Grips	Grips are usually made of firm or soft plastic, foam, gel, or sometimes leather. Depending on expected use or desired price. They may be simply smooth and round or molded to fit the shape of a human hand better.
Handlebars	A lever attached, usually using an intermediary stem, to the steerer tube of the fork. Allows steering and provides a point of attachment for controls and accessories
Headset	The bearings that form the interface between the frame and fork steerer tube
Hubs	The core of a wheel; contains bearings and, in a traditional wheel, has drilled flanges for attachment of spokes
Lock ring	A ring, usually metal, of varying design, that serves to retain a component in place
Nuts	A fastener with female threads, usually hexagonal on the outside to fit a suitable wrench.
Pedal	Mechanical interface between foot and crank arm. There are two general types; one secures the foot with a mechanical clamp or cage and the other has no connection to lock the foot to the pedal
Rims	That part of a wheel to which the tire is attached and often forms part of the braking mechanism
Seat	What a bicyclist sits on
Seatpost	A post that the seat is mounted to. It slides into the frame's seat tube and is used to adjust ride height depending how far into the seat tube it is inserted
Stem	A bracket used to attach handlebars to steerer tube of fork. Usually secured by pinch bolts
Wheels	As in common usage. Traditionally and most commonly spoked
