Today morning we learned about integrated circuits which convert analog signals to digital signals, this is helpful since many physical phenomena give rise to analog signals which must be processed by computing devices that are digital.

In one activity, we used the converted signal to determine the potential difference across a rotary potentiometer which in turn can be used to determine angular position of a robot arm connected to the potentiometer. In the afternoon we learned about temperature sensors. We finished the day by experimenting with the various components at our disposal.

Today, four alumni from prior cycles of the RET project at NYU-Poly visited and spoke to us. They shared their experiences on using their learning and knowledge gained from the project in their schools and classrooms.
