For me this was the missing piece to the platform, being able to do some kind of real-time debugging of values during execution. The Serial. library that comes with the Arduino allows you to interact with it while it’s running, which is great. Besides some of the Serial.print(ln) functions that I showed in quite a bit of the Lab 10 code, this lab work was really focused on getting input through the Serial interface. The code for this exercise is below…. Continue reading “Part 11 – Using the Serial Port”
Part 10 is where we learn to connect the hardware as both inputs and outputs using the code in the micro-controllers. This is the beginning of how to build bigger devices. The first part of Lab 10 is a primer on how to write some simple code to blink and LED connected to the Arduino. The Arduino setup looked like this….
Here is the Star Wars game. You win by getting all rebel pilots, lose by getting all storm troopers but when you lose you get a 10,000 point bonus. I call this game Millenniums Win. Continue reading “Part 11b – Code.org Start Wars Game”
Part 7 was our first try at connecting our hardware circuit with the software based Arduino controller. The lab began with a short explanation of the Arduino and then moved right into building the first controller. The lab itself was pretty simple as all we were required to do is wire up an LED to the Arduino. I took it a little further and decided to control a few LED’s.
Part 9 allowed us to take what we learned in the previous labs and extend the simple on/off of the motor and direction to leveraging the how to work with different loads as well as analog outputs..
|Next we measure the voltage and current being produced by the circuit.|
|Part 9 complete!|
Part 8 had us using a relay, the transistor and resistor to control a simple motor in two directions. Here is what it looked like when it was working.
In part 6 we learned about the device that helped users in the computer age, the transistor.
Part 5 built on what we started in part 4 adding control of the output using switches and relays. We started the lab by putting a simple switch into our LED configuration. Then we moved on to a more complicated 3 way switch setup, funny considering I had just installed 6 of these in my hope. It was awesome to understand how they worked.
Part 4 is where we started to get into more complicated circuits. The first part of the lab laid out some of the notation used to communicate these circuits. First, we tested the circuit we built from part 3 with a different wiring, which didn’t work. Next we moved on to testing LED brightness using different resistors. Which one was brightest, the with the least resistance of course, the 100ohm.
