We had the idea to further influence and control the sounds with an external switching device.<br> | We had the idea to further influence and control the sounds with an external switching device.<br> | ||
Our solution was a chain of two relays [http://cdn-reichelt.de/documents/datenblatt/C300/RELAIS-FTRK1.pdf (this one)] controlled by the arduino via a darlington transistor [http://www.pollin.de/shop/downloads/D101063D.PDF ULN2803]. | Our solution was a chain of two relays [http://cdn-reichelt.de/documents/datenblatt/C300/RELAIS-FTRK1.pdf (this one)] controlled by the arduino via a darlington transistor [http://www.pollin.de/shop/downloads/D101063D.PDF ULN2803]. <br> | ||
These relays allowed us to turn the sound on and off so that little pieces of the sounds could be cut out. | These relays allowed us to turn the sound on and off so that little pieces of the sounds could be cut out. | ||
We stopped our experiment as soon as we realized that we would need a lot of (expensive) relays to control<br> every available sound on the toy chip.<br><br> | We stopped our experiment as soon as we realized that we would need a lot of (expensive) relays to control<br> every available sound on the toy chip.<br> | ||
