Step into the foggy shores of New England in this thrilling episode of Paranormal Circuits! Join host Rachel De Barros as you unravel the mystery of an abandoned lighthouse, haunted by whispers of the past and flickering lights with no power source. Follow the story of Captain Arthur Darby, a WWII lighthouse keeper, and his unfinished mission—then grab your Arduino to decode a ghostly SOS and restore the beacon's light. Part supernatural mystery, part hands-on electronics tutorial, this episode will have you building your own Morse code signal as you uncover the secrets of Beacon Point. What you'll learn:

• How to write and upload an Arduino sketch to blink the Arduino's onboard LED in a specific pattern.
• Using the digitalWrite() function to turn the LED on and off.
• Timing the LED blinks with the delay() function.
• Incorporating for loops to simplify repetitive code in Arduino programming.
• Practical tips for debugging and troubleshooting code for Arduino projects.

If your podcast app supports video, you can switch to video mode during the build and coding segment for a closer look at the hands-on details. But don’t worry—everything is explained clearly so you can easily follow along with just audio. And if you’d like extra resources, the video version is also available on my website, complete with step-by-step guide, wiring diagrams, build instructions, and code to help you solve the mysteries behind your own electronics projects.
