Out of another time, the “Cybot” robot was a major step forward in the democratization of robots in 2003. In the form of a bi-monthly booklet available in bookshops, it was sold as a kit to be assembled. During the months several evolutions have allowed to go so far as to be able to program…
In the video is presented the creation of a schema and a typon with the free software Fritzing. The project is a simple adapter between a YM12864 graphic LCD and an I2C MCP23017 control module. Lcd display The model is a YM12864C and its control interface is the parallel bus. I2C module MCP23017 This module…

In the different possible solutions there are: draw the circuit by hand, if possible, with a marker directly on the copper plate. Clearly the quality is not there but for very simple small…
