FLASHING LED

In this Instructable you will make a LED flasher. You will also be able to adjust it.

Step 1: Bill of Materials

parts:
  1x 555 timer
  1x LED
  1x 9 volt battery and clip
  1x 220μf capacitor
  1x 101 Ω resister
  1x 101 Ω variable resister
  1x 900 Ω resister
  multiple wires
  breadboard

Step 2: The Schematic

Here is the schematic for the flasher.

Step 3: Insert the Wires and the Timer

Connect pin 2 and pin 6. Connect pin 1 to the negative of the battery clip. Connect pin 8 to the positive side of the battery clip. Sorry for the bad pic.

Step 4: Connect the Other Parts

Connect the 220 uf capacitor between pin 1 and 2. Connect the led anode(+) to pin 3. Connect the led cathode(-) to the 101 ohm resister. Connect the other end of the resister to ground(-). connect the variable 101 ohm resister between pin 8 and 7. Connect the 900 ohm resister between pins 6 and 7.

Step 5: Your Done!

Yay, your done! You can change the frequency of the blinking by turning the variable resister knob.
