Week 2: 29 January

Thursday Class:

Introduced the Arduino IDE and used it to blink the LED.
Changed the blink frequency until the light looked continuous.
Looked at the signal used to drive the LED with the oscilloscope.
Here's the modified Arduino code we developed.

Tuesday Class:

We will continue on assignment 4, Arduino measurements of atmospheric properties.


Continued with LED circuit: Discussed use of the digital volt meters, resistors, resistance color bands and resistance values. Calculated LED current and breadboarded LED circuit to light LED from the Arduino 5 Volt power supply. Discussed accuracy and precision for resistance measurements.

 


Note that Assignment 1 is an online assignment, and is due on Sunday night; it's about radar.
We will do Assignment 2 together.
Assignment 3 is also an online assignment.
