Summary

I made this nightlight for my daughter. It uses Adafruit Neopixel LEDs and an Adafruit Pro Trinket (Arduino) to control them. I also added a BLE chip. The colors and animations can be controlled from an iPhone or iPad.

Print the box at 1.5x
Print the base at 1x (no scaling)

Both need supports turned on.

The screw holes are sized for 4-40 screws.

Another user created some inserts for the original lamp (these would be replacements for the plexiglass that you used on the inside. I modified his model to work with your lamp design and figured I'd share.

Great Project!..Im in the process of creating one, but i get an SPI error while compiling your code. any ideas?
class SPIClass' has no member named 'usingInterrupt'

What version of the Arduino IDE are you using?

I got it to work by using adafruits version 1.64. Now the issue is my pro trinket doesnt want to get into boot mode. As soon as i plug in the usb for programming the red led flashes 3 times in a non stop sequence

There is a tiny push button near pins A4/A5. Push that button and the pro trinket will be in boot mode for 10 seconds.

Got everything all wired up and working...well sort of. Im using Android and I don't think the code works well with android devices. The BLE seems to freeze up and disappear from the available devices. Do you experience this on IOS?

I do not have that problem on iOS. I've tested my cube with an iPhone 4S, iPhone 6 Plus and an iPad Mini. I've heard BLE is pretty terrible on some Android devices.

How difficult would it be to modify the code to work with the hc06 bluetooth module?

I don't think it would be super difficult. Looks like that module just serial data just like the adafruit BLE module. The hc06 has to be connected to RX/TX instead of SPI. I think it would just be a matter of writing a new function to read the serial data. Basically just replacing 'BTLEserial.read();' with a function that reads serial data from the hc06.

The reason I ask, is because the BLE is not compatible with App Inventor. So for future projects that you'd want to create an app for you would have to use the HC06 instead. It would be nice to create an app with all your custom commands set as buttons.

Comments deleted.

I had an extra 12v wall wart power supply laying around and I didn't want to use a usb connector. Barrel connectors are much more sturdy. If you are using NeoPixel LEDs you will need to supply 5v to the LEDs separate from the 5v pin on the Trinket. The NeoPixels draw a lot of current.

makes sense...Im going to use the a 5v wall power supply with the Barrel connector..but i will omit the buck converter and just add the Cap. Should be fine with the NeoPixels.

Love the bluetooth idea ! At one point when I was working on mine I was going to have a microphone in it so it could react to sounds, but I decided that I just had spent enough time futzing with the design/code, and wanted to move onto other projects.

Awesome !!!
I've always wanted to do that with my design but never taken the time to do it
