09/06: Looking closer --- [basic components]
Today is the day of elements! We will go over and experiment with key componets to electronics.
We will go over together:
- What is electricity?
- Properties of electricity (water analogy)
- Elemental electrical components
- Prototyping materials
- Using a multimeter
- Ohm's law
- Reading resistor codes
- Reading schematics
- First circuit
- Soldering demo
- Soldering components to Perforated board
- Testing your board
- Trouble shooting
- Handmade switch

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

Switch making - materialization of binary thinking
- Make two switches that fulfill the requirement of one of the followings. Two switches must be working with two different requirements from eachothers.
- It requires you to use a part of your body (not fingers) or gestures to activate
- It requires more than one person to activate
- require objects to activate
