๐ ๏ธ Build instructions
- Place the NE555 IC in the middle of the breadboard, across the center channel.
- Connect the 1 kฮฉ resistor between pin 7 and supply plus, and the 470 kฮฉ between pin 7 and pin 2. Tie pin 2 to pin 6.
- Fit the 10 ยตF capacitor between pin 2 and minus (mind polarity: capacitor minus to supply minus).
- Wire the LED in series with the 330 ฮฉ resistor from pin 3 to minus. The LED's long leg goes toward pin 3.
- Tie pins 8 and 4 to plus, pin 1 to minus. Power from a 9V battery. The LED blinks about once per second.
