Escape Room Puzzle Tutorial - "Make The Flowers Grow"

In this video tutorial, I'll explain how I created an escape room puzzle using an Arduino UNO to set the correct lighting conditions to make three flowers grow :) The Arduino reads the value from three sliding linear potentiometers, which it translates into an RGB value. That value is sent via a DMX shield to set the colour of a stage light. If the colour matches the colour of petals on one of the flowers, that flower grows up towards the light!
This could be used in an escape room puzzle if, once all three flowers have fully bloomed, a message can be read from their stems, or an item retrieved from the tips of the flowers, or any other effect triggered by the Arduino.

That's a really clever use of relays to change the polarity. Definitely will keep that in mind for future projects, thanks!

fun to see something new from you.. been some time ago.. wish I could be as good as you on these things.

Thanks for sharing 👍

This looks really fun, you could also even do temperature or have a little water pump that just cycles water. How i would do this is have a book of flowers that all have their "growing" conditions and younhave to identify the plants based on how they react to the changes in environment. Maybe via process of elimination. Maybe instead of a relay use a transistor and if you get one factor right, you analogwrite 128 so it moves slower than if it had 2. This is such a cool puzzle! Im currently struggling to make multiple microcontrollers to communicate with each other via cables, would you be interested in doing a tutorial in how you make your puzzles talk to each other?

Thanks for the comment! Re: Communication between devices - yes, sure - there's lots of options available, I2C/SPI/UART, UDP/TCP/MQTT over Ethernet/Wifi, Bluetooth, or RS485/Modbus/Canbus, or proprietary systems like ESPNow.... which devices are you trying to network, how many of them are there, and what is the maximum distance between them?

Can you remove some jitter by rounding in code ?
