Ahoy !..

I was rather dismayed when I saw my Mega attach with an Arduino service and I got a endless
error

Hello,

I would absolutly be grateful for just a bit of help to push me in the right direction.

I would like to read the data from this sensor 

https://wiki.dfrobot.com/DFRobot_Ambient_Light_Sensor_SKU_DFR0026

connected to an arduino uno. Can someone give me some example code to help me along?

I have the uno successfully connected to MRL and have been able to control a servo with the service so I have things correctly connected.

Walking robot series

This is an interesting series about designing a walking robot. https://www.youtube.com/playlist?list=PLpwJoq86vov-C5SldDA-AhxesVHPRk74x  most of this is above my head, but might be useful to Ray in his newest challenge.


RasPi UI Proposal

Here's a quick mock-up of the RasPi service UI.
Having a pin out reference I always find useful ...  can prevent blue smoke sometimes :)
Alexinator40 and Ray have been suggesting a generalized I2C interface.  I think components from the Serial service can provide a UI which allows for generalized reads and writes to devices on an I2C bus.
The buttons on the right would be just to read and write GPIO pins..


OpenCV WebGui Progress

More progress with OpenCV webgui. 


Motors Refactor

GroG's picture

Ahoy !

Now with OpenCV stuff merged on the develop branch - the branch I'm working with is closer to develop.
The largest amount of change on it that is different has to do with Motors and MotorControllers.

Motors in the past always required a direct reference to a controller.  

I don't think this is a very good design.
