Day 3

Topics

• Using pulldown resistors
• programming

Lab

This particular sketch has the effect of increasing the delay in ever step of the loop until it increments for 10 cycles then it starts over.

It took a little while but i talked my way through the working of the resistor in the circuit. Without the resistor the only current flows when we have the button pressed. This leaves the the possibility of a signal from sourrounding elements. We need the resistor bridge to so there is always a path for a current to ground. The resistor has more resistance than the button we choose so it leaves a lower resistance path for current when we have a button pressed.

Homework Notes

 I have to get a computer working because I forgot to send over my finished programs for the amino acid assignment and ended up trying to write the entire things again in the time between my classes. It was a valiant effort, overall a screwup. Fortunately I should have this worked out by thusrday. All i need now is to get a network card because the wifi is dodgie.

Lecture

Remember! Any curve, when properly constrained is an example of a linear curve. ALWAYS FOCUS ON WHERE YOU'RE CONSTRAINTS ARE.

Programming

   This was the first attempt I made at doing the programming homework. I put in a little check to make sure the number is a positive number.

   This worked after some slight debugging. I had msspelled some printf and used a backslash where I should have used a forward slash.

The next step was to write a function that computed the same thing but with base 8. This was a change of one number and that's it.
