Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: the Schematic Diagram.
Follow the schematic diagram for this circuit.
Step 2: Insert the Transistors and Resistors.
Fix the 2 transistors in your .Then insert the wire to the transistor to the breadboard negative side.
connect the 2 100kΩ resister to the breadboard as shown in the image.
Then you connect the 2 470Ω resister to the breadboard as shown in the image.
Step 3: Insert the Capacitor.
Insert the 2 capacitors as shown in the picture. Put the negative side of the caps on a free rail on the breadboard.
Fix the jumper wire and LED as shown in the image.
Step 5: Connect the Battery.
Last and finally connect the battery to the breadboard.as shown in the image.
Step 6: You Can Put Both Side
You can put both side LEDs.and you can put straw upon the LEDs.it look like nice.
