Pumpkin LED Fader

The 30th and 31st of October, 2024, our class decided to make a Halloween-themed project. We assembled a "pumpkin LED fader". This simply meant that we assembled a circuit using a 555 timer to fade a light in and out to make the illusion of a pumpkin breathing. The 555 timer controls the LED without needing code as it detects voltage drops through its Pin2(trigger) that triggers the output(the LED) to go high(light up!). We assembled the circuit first on Tinkercad, then on a breadboard, and then on a mini PCB board. Below is the process:

We started by creating the circuit in Tinkercad.

We then made the circuit using a bread board.

We then transferred it to a mini PCB board.

This is a video that shows the PCB working and fading. It does not fade completely out, but it still glows brighter and dimmer at some points.
