Pumpkin Bucket

thingiverse

A Halloween without candy is a trick! Don't venture outside without this cube with flashing lights. This is an easy impression, but it's quite large. Measuring approximately 120 mm round and 80 mm high, no supports are required to print at 0.2. The pieces fit perfectly together; using glue isn't necessary. For the handle, you can use a wool yarn. Insert the thread through the holes and tie a knot. You can use the pumpkin bucket without lights, but adding them is a great idea. Here's what you need for blinking lights: One Arduino nano Five yellow LEDs Five 220 Ohm resistors One 9v battery One 9v battery adapter Wires Here are the schematics to follow:  Assembly is a breeze. Here's how to do it: Step 1: Solder the LEDs with the resistors. Step 2: Solder the cables according to the schema. Step 3: Glue the LEDs in place using hot glue, placing two in the eyes and three in the mouth. Step 4: Connect the LED cables to an Arduino nano on pins 5 and 6. Step 5: Connect the battery and insert the circuit into the pumpkin. Step 6: Place the bucket inside the pumpkin.
