It shows a graph of the signal - the x axis of the graph is voltage and the y axis is time. You need to set appropriate voltage and time scales in order to see the voltage on the screen. We used the pocket oscilloscope to observe the voltage across the LED as we changed the parameters of the light blinking Arduino IDE sketch. The key to being able to observe the trace on the oscilloscope is setting the voltage and time scales to the right values for the signal we want to observe. The pocket oscope can only go up to about 200 khz, plenty of bandwidth for what we were looking at. diff --git a/docs/assignments/week06/images/msg1291006763-136 5861860271403830177 b/docs/assignments/week06/images/msg1291006763-136 5861860271403830177 new file mode 100644 index 0000000000000000000000000000000000000000..94da9ab8be6957c1466a6a165206d6fa6ccfb361 --- /dev/null +++ b/docs/assignments/week06/images/msg1291006763-136 5861860271403830177 @@ -0,0 +1,7 @@ +<html> +<head><title>404 Not Found</title></head> +<body> +<center><h1>404 Not Found</h1></center> +<hr><center>nginx/1.18.0</center> +</body> +</html> diff --git a/docs/assignments/week08/embedded-programming.md b/docs/assignments/week08/embedded-programming.md new file mode 100644 index 0000000000000000000000000000000000000000..a9fd03327db1e9def4796d51aed47c72704a642a --- /dev/null +++ b/docs/assignments/week08/embedded-programming.md @@ -0,0 +1,3 @@ +#Embedded Programming + +Group assignment: compare the performance and development workflows for other architectures diff --git a/docs/assignments/week09-molding/molding-and-casting.md b/docs/assignments/week09-molding/molding-and-casting.md new file mode 100644 index 0000000000000000000000000000000000000000..4021344982bcd130a159c84d05fb5dcf581afbaa --- /dev/null +++ b/docs/assignments/week09-molding/molding-and-casting.md @@ -0,0 +1,7 @@ +#Molding and Casting Group Project + +Group Assignment: + + review the safety data sheets for each of your molding and casting materials, + then make and compare test casts with each of them + extra credit: try other molding and casting processes
