How do I come to terms with a encoder that has CLK and DT?
here is a counter that uses no ISR
https://www.hackster.io/vandenbrande/arduino-rotary-encoder-simple-example-ky-040-b78752
How does the pan and tilt wire up when encoders are included?
Camera
FBCJustin Streaming todo.
Summary of step 1 desired feature set:
1. stream live to internet
1a Existing live stream to You Tube is sufficient for now. We must solve the erratic upload problem now, before we move on. Retry this with internet box tied down and power lead secured.
Why do we have to occasionally hard reset the internet box?
Heavy power switch. Where did the “power Conditioner” go?
Laptop boot on power, sleep on power down
2 allow real-time camera switching
2a – Implement camera feed switch.
2b – laptop to control switching interface
2c – Router from home to mount in 19 in. Rackd. – 2.d current inputs : 1 Sony camera remotely steered, 1 Sony camera fixed at sound booth.
3 use one remote camera and one fixed camera for now.
3a. – one remotely controlled camera
3b- Pan/tilt mechanism / controller done, needs tuning.
34c- zoom, focus etcetera.
3d-Evaluate lanc dongle. Buy. Camera XA35.
3e Camera drive. Lanc drive. add joystick or wheel to LANC zoom
4 Use mixed audio stream from existing sound board.
4A Why is the fan in the switch so loud?
4b. Key to switch / software /
4c – do we have audio coming in from Sound Booth Channel 8?
4d Get app to work on nexus tablet.
4e. Sound Board private network
SSID X-32

5 Send use able stream of camera feed for ProPresenter to display on projectors. Use ProPresenter as a input “Camera” source to switch.
Is ther a way to with the exsisting video on the Lightening outputs

This code includes the ddition of fade in and out PWM. Also a stop feature. And the addition of individual functions for motor control
This was a revision of the example sketch that originated from Pete Dokter's code for Arduino that shows very basically how to control an Ardumoto
motor driver shield with a 5V Arduino controller board. http://www.sparkfun.com/datasheets/DevTools/Arduino/Ardumoto_test_3.pde
This also includes parts of the Fading Example, Created 1 Nov 2008 By David A. Mellis, modified 30 Aug 2011 By Tom Igoe http://arduino.cc/en/Tutorial/Fading

/* Let's take a moment to talk about these functions. The forw and back functions are simply designating the direction the motors will turn once they are fed a PWM signal.
If you only call the forw, or back functions, you will not see the motors turn. On a similar note the fade in and out functions will only change PWM, so you need to consider
the direction you were last set to. In the code above, you might have noticed that I called forw and fade in the same grouping. You will want to call a new direction, and then
declare your pwm fade. There is also a stop function.

How can wordpress download a single post to a pdf?
Hi ddenhartog,
You can just need to tick the checkbox “Enable single post download” on the plugin settings. This option is under “Post PDF Export > Post PDF Export Options”.
For other ways to put download button on your post you can check the plugins documentation herehttp://cmdino.com/post-pdf-export/
How can I download large amounts of files from Google Drive to local desktop.
Okay I have found a third party app that lets me copy everything from Google drive in one easy step – Astro File Manager – it’s a free app on play store, works brilliantly for this as you can select everything in the drive and simply copy it over to your SD Card.
This app will also work with dropbox and other cloud services.
