(mostly me talking today)
How to read a data sheet using L293 vs. tutorials
How would you do your project differently using a bridge? Is coasting a useful feature?
How do interrupts work with motion?
How do state machines work with interrupts and motion?
Using chips to simply interrupts
Let’s say you have to interrupts, and you only care if both of them happen at the same time. You could feed both inputs to an AND chip that we have in A10 and feed the output to a single input interrupt. Likewise, if you have two inputs and you care if either one go off and will do the same thing for each, use an OR chip.
Use state variables to change solenoid / motor based on an interrupt
Talk about crits and elevator pitches.
Simple assignment
- Verify that your Teensy boards are working and that you can download sketches.
- Skim the Teensy 4.1 page and think about things you can do in future projects / crits. Update Looking Out if you find something interesting using the Teensy chips in ixd projects.
