Suitable for ages 7+. No electronic skills required. No soldering involved. Hand out to each participant (limit ~100) packs containing instructions & parts (solderless breadboard, batteries, and some electronic parts). I will perform step-by-step live demo, building a simple but flexible electronic circuit (LED flasher). If time allows,do a few mods to show its flexibility: n* Mod #1: replace LED with orange, yellow, or green LED.n* Mod #2: white LED - using 4 batteries.n* Mod #3: metronome -- add speakern* Mod #4: audio oscillator (Voltage/current/resistance/light to frequency converter)n* and many more!
