Hi I am looking for a UV Sensor that shows current intensity and accumulated light over time. Does anyone have any suggestions? I was looking at: Grove - UV Sensor, ML8511 and VEML6070.
@isded from what is explained in this page it seems it is based on the Semtech SX1278 :

I have got the accelerometer (MPU6050) working as a service in nordic mbed, and I thought I would throw in some of what I learned to add to the great work you have done.
Hello Jeelet,
Thank you for the encouragements.
Your advice to save (protect) the Oled screen is also welcome, thank you.
My code expects it, the text is mini and moves every 3 seconds. Press a key and the menu returns.
Cordially.
I just tested 2 led types with no flicker on my attiny circuit.
It is funny, the expensive leds like from philips: Dimmable 3.8W Warm White have a flickering behavior .
A cheap one available in Action from LSC 6.3W, Dim to Warm and 460 Lumen has no flickering behavior.
Another one from Osram Par 1650: 5.5W Dimmable Warm White, 350 Lumen also has no flickering.
The philips has the best Energy savings though : 4kWh compared to 7kWh for the LSC one.
Is there a relation between energy savings and dim quality ?
I would like to step up 3.3V from my power supply with the help of a dc-dc-boost converter to 5V and then I want to draw 500mA by placing a 10 Ohm resistor between the output-pin of the boost-converter and ground.

I finally got it to work. Look at my post on the Home Assistant forum.
There is an amazing thing that someone in the MySensors world did that makes RPi I/O very easy! Just like the Arduino, one uses the code:
pinMode(MphysicalPin, OUTPUT);
I couldn't believe my eyes when I saw that. And then got double flabbergasted when I discovered that pin is the physical pin of the RPi! No mapping of GPIOi to the pins.
Whew!
So the I/O was easier than both of us could have imagined! @mfalkvidd if you know who did this, send them praise and thanks.
