Friday, 30th of September 2011 - Control of flame output

Because we will now be needing to control how many flames are active we will need a device that is able to actively and easily "knock on- and knock off" using the already designed gas release mecahnism:

Gas release mechanism(link)

As this is applying a principal of using a lever to "knock" a wedge into place - we will need to use something that can control what a which lever it is pressing.

Such a device can be a servo-motor: (this video shows the function of a servo motor)

Servo motors have the ability to rotate to specific angles, both clockwise and counter-clockwise. This can be applied in our gas release mechanism in a way that each gas release mechanism will have a specific position in the ring to which the servo motor can rotate too:

Sketch: Servo motor positioning

The sketch shows how the servo motor might rotate from one position to another from the control of the Arduino circuit board. The servo motor will have an arm attached to in that can spin around with the shaft and knock the wedges into place to release the gas.
