2 jumper wires
1 3.3 Ω 1/4 Watt Resistor
2 Pushbutton (Micro Momentary/ Normally Open)
4 AA Batteries
1 Battery Holder (4 AA batteries)
1 Mini Breadboard
Please note that these are very basic instructions that assumes some familiarity with electronics. However, don’t despair if you run into trouble or are a beginner. Watch the video, Minecraft Circuits in Real Life: Episode 6 Buttons in Series, for a more comprehensive instruction.
Prepare the battery holder. Insert 4 AA batteries into the holder. The black wire will be the negative side of the current whereas the red wire will be the positive side.
Insert the black wire into the bottom left hole (A1) in the breadboard.
Then insert the the pushbutton with one pin in E1. The second pin on the same side should fit into E3. The other side of the switch should fit in the holes on the other side of the middle gap (top half of the breadboard) F1 and F3. Make sure the button is secure.
Insert the second button right next to the first, with its pins E6 and E8 with the other side in F6 and F8.
Connect the two buttons by running a jumper wire inserted G3 and G6.
Run a second jumper wire running from D8 to E11.
Insert the resistor in D11 and D15.
Then, insert the negative end of the LED in the slot E15. Place the positive end of the LED in E16.
Insert the red wire from the battery holder into the slot A16(the same row as the long end of the LED).
Finally, press down on both buttons and then each individual button.
