| + | * Skyped with Jerry for more details on the ultrasonic sensor | ||
| + | * Learned that the Teensy runs at a 96 MHz clock speed, allowing for a measurement of smaller amounts of time (crucial for the ultrasonic to work) | ||
| + | * Jerry gave us an in-depth explanation of how the ultrasonic sensor works | ||
| + | * Also learned that the ultrasonic receiver only receives the sound signal (inaudible) only in the 40 MHz spectrum, meaning that external noise such as car horns was not an issue | ||
| + | * Words of wisdom from Jerry: don't focus on being stuck on a problem, just move on to another problem | ||
