09/06: Looking closer --- [basic components]

Welcome back!

Today is the day of elements! We will go over and experiment with key componets to electronics.
We will go over together:

1. What is electricity?
2. Properties of electricity (water analogy)
3. Elemental electrical components
4. Prototyping materials
5. Using a multimeter
6. Polarity
7. Ohm's law
8. Reading resistor codes
9. Reading schematics
10. First circuit
11. Soldering demo
12. Soldering components to Perforated board
13. Testing your board
14. Trouble shooting
15. Handmade switch

Soldering

Soldering is a skill, and you will get better with practice. Don't worry too much if it seems hard now. Take your time! We will go over together:

1. Soldering temperature is typically 650 degrees F / 350 degrees C. It's very hot!
2. Never leave a soldering iron on while unattended (our soldering stations only take about 10 seconds to reach temperature)
3. Always use helping hands to hold wire and electronic components
4. Most soldering jobs will only take a few seconds of contact. Check iron temperature if it's taking longer
5. Do not use soldering irons to burn or melt things. We have a heat gun for that kind of work
6. Do not eat or drink while soldering. Be sure to wash your hands to minimize possible lead exposure
7. Use a fume extractor and goggles when soldering.
8. Take your time!
