Carbon Film Resistors

This is the 2nd video in the Arduino Workshop tutorials series in which I show how to properly use a transistor to amplify a digital output pin. This is a must when you have to drive high current devices from an arduino like high power led’s and motors. Any questions or comments are welcome please post them!

I hope i have explained everything in a clear enough manor for you guys to follow this tutorial. Please note i only used one resistor in this setup so please ignore the error on the vid You will need: Soldering iron Drills and other various tools for making holes in the model for the wire 9v square battery PP3 9V Battery Connector Clip Snap on SPDT Miniature Vertical Slide Switch 0.5A 50V DC 1K OHM 1KR CARBON FILM RESISTORS 1/4W 0.25W 1000 3mm White Ultra Bright LEDs – 12V Fibre Optic Cable 0.2mm wire for LED’s HEATSHRINK 3mm & 1.6mm

Electronics Class – Room 101 where I teach beginners everything about electronics. This is part 1 of a series on all opposition and resistance. I offer comment during the various types of resistors: Carbon film wound, metal film, precision, variable, ceramic and wire. I also show a series parallel resistor networks and measure the voltages with a voltmeter. Resistances vary in wattage. The wattage rating indicates the amount of energy that can be dissipated by this resistor. At some pointResistors burn out. Lower resistance to burn with high currents. High resistances blow of high voltage. By Ohm's law one can calculate circuit voltage, current and resistance. E = I x R I = E / RR = E / I. Ohm's law is easy to use and remember, because a simple pie chart, you can always fall back. Cover the value that you do not know and calculate the answer. Resistors will always "open" circuit, when they fail. A resistor can be the power of all things. And wire resistance. Hope you enjoyand learn a little something.
