Pumpkin with light effects and sound

A hollowed-out pumpkin with a candle in front of the house, children who will come to ‘trick-or-treat’ and beg for candy… Halloween is a festival that is now also increasingly celebrated in Europe. With an eye on the approaching Halloween date, the Elektor lab had the enlightened idea to develop an amusing circuit for pumpkins, which produces both light and sound effects.

The result is impressive, particularly if the circuit is housed in a real, hollowed-out pumpkin. During testing, several of our colleagues at Elektor Castle (mainly the women) appeared to be briefly frightened when they approached the pumpkin and were taken by surprise by the flashing lights and a terrifying cry or scream from the pumpkin.



To realize all this, we have designed a small circuit, which is provided with a proximity sensor, a number of LEDs, a sound module, a small audio amplifier and a loudspeaker. All this is under the control of an AVR microcontroller. And this project is suitable not just for Halloween! With a few Christmas carols on the SD card of the sound module this is also a very nice gadget for the upcoming Christmas festivities. And using the kit that we have put together for this project, it can all be built very quickly.

This amusing circuit hopefully contributes to the goose-bumps atmosphere by making such a hollowed-out pumpkin interactive, with both sound and light effects!
