Yeast screen

Having established that yeast responds with light to electrical impulses, we consider to control an array of 96 pixels totally independent, so we can create moving figures and it would be the first screen that works with living cells.

To do this we had two problems, to control each pixel independently and build a stand with 96 pairs of electrodes (one for each pixel) to stimulate the yeast.

1) To control 96 pixels. Our screen is a matrix of 8 columns by 12 rows. Thus, we can decide which row and column we want to activate at all times through a card with 20 digital outputs, one per row and column. For example, to turn the cell in position 3,4 of the screen, activate the outputs corresponding to row 3 and column 4. The card is controlled by a program executed in LabVIEW.

2) Costruction of the support.
