| * Further ran tests with the ultrasonic transducers using a function generator and oscilloscope. We found out that we don't actually need a sine wave to drive the transducers, and that a square wave would work as well. This is good news since square waves are much easier to produce than sine waves. | * Further ran tests with the ultrasonic transducers using a function generator and oscilloscope.

| * Tested transmitter with 3.3Vpp, 40kHz square wave. Result is 400mVpp sine wave. This isn't bad, (much better result than previously), but we would need an amplifier circuit to increase this signal. | * Tested transmitter with 3.3Vpp, 40kHz square wave.
