Original Gravity: Analog Rotation Potentiometer Sensor for Arduino – Rotation 3736?? – PartsCountry

Description

Tiny FX is an effects controller for the LED dots and strips that can be found in third-party LEGO?-compatible lighting kits. These LEDs are connected up by thin, flexible wires that can easily be concealed around/behind/within your model. Typically they’re powered directly from an alkaline battery pack or USB, so the LEDs are lit all the time – and we wanted our illuminated creations to have more smarts!

Adding a Tiny FX means you can do fun stuff like:

• Adjust the brightness of the LEDs
• Simulate movement with dynamic lighting effects
• Turn the lights on and off in response to environmental triggers/sensor readings
• Pulse them atmospherically for a spooky ambience
• Flicker them on and off to make cool fire effects
• Accompany your light effects with appropriate sound effects (zhwhom)

Tiny FX can drive six channels of two-pin mono LEDs and one channel of four-pin RGB LEDs*, and it has indicator LEDs so you can see what each channel is doing. It’s got an onboard amp and connector to attach a tiny speaker, a Qw/ST connector so you can add Qwiic or STEMMA QT breakouts and an additional sensor connector for hooking up hardware like buttons, potentiometers or PIR sensors.

Tiny FX is perfect for adding custom light and sound effects to your favourite construction kit models, dioramas, papercrafts, doll houses, book nooks and shadowboxes. If you don’t already have a lighting kit that you want to upgrade**, we stock a range of LED dots and strips, cables and expanders as well as battery packs and power cables.

You can buy a Tiny FX on its own, or bundled with a convenient selection of LEDs, a speaker and cables to help you start lighting stuff up ASAP – you’ll just need to supply your own AA batteries. Just click the Starter Kit version before adding it to your cart!

• 1x 4-pin JST-SUR connector for attaching RGB LEDs, with RGB LED indicator
• USB-C connector for power and programming (1A max)
• Reset and BOOT buttons (the BOOT button can also be used as a user button)
• 2-pin JST-SUR power input connector (1A max)
• 3.2W I2S mono amplifier?with 2-pin?(Picoblade-compatible) connector for attaching speaker

Software

Tiny FX comes pre-loaded with pirate-brand MicroPython and our?shiny new PicoFX library?which makes it easy to run multiple simultaneous light and sound effects – we’ve provided many?examples?to show you what it can do. If you’d rather roll your own software, I2S audio and toggling LEDs should be possible with most Raspberry Pi Pico ecosystems.

Notes

• This board is not really designed for driving addressable LEDs/Neopixels. Check out?Plasma 2040 if you want a board that’s designed to do that!
• We’ve tried Tiny FX with a number of different lighting kits, and we found it works best with ones that have the LEDs as separate components that you attach together using?expansion boards. Some kits come with the LEDs pre-wired together into one harness with a single USB connector on the end which makes things more awkward – if you have one of these you might end up needing to splice some connectors onto the end of the wires.
• Tiny FX measures 31.2 x 23.2mm x 6.2mm (L x W x H, including connectors). Fortuitously, this fits within the footprint of a 4 x 3 brick in popular ABS brick-based construction kits.
• The JST-SUR connectors are very tiny. Tweezers might help when plugging them in!
• For stealthy operation, the indicator LEDs on Tiny FX can be disabled by cutting the trace?on the back of the board labelled with an LED symbol.
