Concept
I recently decided to embark on a fun and useful project – creating a switch that would only complete the circuit when the key is inserted into the lock of my drawer. Not only does this switch serve a practical purpose by indicating when the key is in the lock, but it’s also a fun addition to my space that sparks conversation and adds a touch of personality.
Method
To create my unique switch, I utilized a simple but effective technique – taping one end of the wire to the lock and the other end to the key. By doing so, when the key is inserted into the lock, the circuit is completed, and the LED bulb lights up.
The use of tape not only makes this project accessible and easy to create, but it also provides a certain level of flexibility. By adjusting the position of the tape and wire, I was able to ensure that the circuit would only be completed when the key is fully inserted into the lock.
Reflection
Overall, I’m really proud of my Arduino-powered switch. It’s a unique and creative way to add some personality to my space while also serving a useful function. And because it’s powered by an Arduino, I can always modify it or integrate it with other devices in the future. I’m excited to see what other projects I can come up with using this Arduino.
