Designing a Doorbell Part 2 - Demonstrating the Prototype and Talking Thru the Schematic

In this part of a multi-part series, I show off my wireless doorbell transmitter prototype. I then go on to talk about the circuit diagram, pointing out the MSP430G2211 microcontroller (same as in the TI Launchpad), the high-side switch consisting of the FDN340P p-channel MOSFET, the 433.92MHz transmitter module, and lots of other things.
