PROJECT: Colour Buddy: Learn Colours With Lights
This system uses a colour-changing LED (RGB LED/tri-colour LED) that switches to a new colour every 5 seconds. Simultaneously, the colour name is displayed on an OLED mini screen (SSD1306). This pairing helps learners connect colour names with the actual shades, making the process engaging and enjoyable.

CIRCUIT IDEA: Dual-Tone Single Bell For Two Doors
In modern homes, apartments, and offices, multiple entrance doors are common. Traditionally, each door requires a separate doorbell, which increases cost and can confuse residents. Hearing a bell without knowing whether it is the main entrance or the back door is a frequent inconvenience. To address this, a single bell device has been designed for two doors, using a common bell that produces two distinct sound patterns depending on which door’s switch is pressed. | | |
