MPLab-X class with Microchip- tonight we have a full house learning servo control! You did attend didn’t you ?
On our intro to laser cutting class. Check meetup for upcoming events!
You must register for this class on Meetup; Limited seating available.
Wednesday, April 17, 2013
You will learn:
How to use a breadboard
What capacitors are
How to use capacitors for filtering power
How to use capacitors for basic debounce/timing circuits
Connect a 555 timer circuit for blinking an LED
This will require the purchase of a breadboard and some more expensive parts that last time (I’m thinking it will be about $15 — I may need to adjust this after I buy the parts). I will bulk-order and get everyone more parts that you need.
700pt breadboard (Like this: )
A few voltage regulators (LM317, 7805) in TO-220 packages
A few 555 timers (DIP-8)
A couple potentiometers (5k, 10k, linear taper)
More resistors (assortment)
Some capacitors (.1uF, 1uF, 10uF)
I’ll update this as I develop the slides.
You will need to bring:
1 power supply – can be a wall transformer that is between 9 and 15 VDC and greater than 200mA output. You should be able to salvage on of these from any number of places.
22ga Solid Core wire (for connecting to you breadboard)
Some kind of wire cutters. I got some of these the other day:
(Small version – will handle anything that can fit on a breadboard)
Some kind of wire strippers. I like these but any kind that can strip 22ga solid wire is fine.
The parts kit from the last class (need the resistors, LEDs, and multimeter from it) or you can buy a kit for $5 (we may not have more multimeters available if you wait too long)
Either $15 or all of the parts that I listed in the parts section above.
Here are the slides from the class: BasicElectronics_1_20130320 . Note: We are preparing a follow up class that dives further into the subject. Please keep an eye out for the announcement.
Chris Cockrum will be hosting another class. This time is for beginning electronics.
There is limited seating available so Please register if you wish to attend. Wed, March 20th.
Part 1. Ohm’s law and Watt’s law
This class will teach the basics of voltage, current, and power. A lab will be included that will demonstrate how to calculate the proper value of resistor to connect LEDs to power.
Parts and equipment may be borrowed from the hackerspace or you can purchase a multimeter (http://www.harborfreight.com/7-function-digital-multimeter-92020.html), a few LEDs, a few resistors, clip leads, and a 9V battery for $5. Alternatively, you can bring your own.
