The Serial Basic is an easy to use USB to Serial adapter based on the CH340G IC from WCH. It works with 5V and 3.3V systems and should auto install on most operating systems without the need for additional drivers. It's a great lower cost option to the extremely popular FTDI Basic.

Serial Basic Overview
The pinout of the Serial Basic mimics the common DTR/RX/TX/VCC/CTS/GND pinout found on hundreds of FTDI-to-USB derivatives.
Pin Label | Input/Output | Description |
---|---|---|
DTR | Output | Data Terminal Ready, Active Low |
RXI | Input | Serial Receive |
TXO | Output | Serial Transmit |
VCC | Supply Output | Power supply 3.3V (default) or 5V |
CTS | Input | Clear To Send, Active Low |
GND | Supply Output | Ground (0V) supply |
Alignment Markers
These GRN
and BLK
indicators are there to help you align the board properly with products that use this same pinout.
The Serial Basic mates seamlessly with products that use the standard serial connection. If you see a board with the BLK
and GRN
labels, then you know it will be compatible with the Serial Basic.
Voltage Selection Jumper
There is a jumper on the rear of the board that controls the output voltage on the VCC pin. By default, the board outputs 3.3V and has 3.3V signals. Changing this jumper to 5V will cause the board to output 5V on the VCC pin with 5V signals.
When the jumper is set to 3.3V, the board uses an onboard 3.3V regulator capable of sourcing 600mA. If you attempt to pull more than 600mA, the regulator will go into short-circuit shutdown where it will only output 150mA.

LEDs
There are two LEDs on the board connected to TX (Green) and RX (Yellow). This is a quick and handy way to see the serial traffic.
Hardware Test
To connect the board to a computer, you will need a standard A to micro-B USB cable. Plug the micro-B USB cable into a USB port on your computer and the other end into the Serial Basic. Your computer should automatically install the necessary drivers and create a COM port on your computer. If you are prompted for drivers, please see the Drivers section.

The quickest and easiest way to make sure everything is working is to do a TX/RX loop-back. To do this, insert a jumper wire between TX and RX. Anything that is transmitted from the TX pin will be echoed back to the RX pin.
Open your favorite terminal program. Select the COM port that the Serial Basic is assigned to, and connect. When you type a character, you should see each character you type echoed back in the terminal.
Which COM Port Do I Need?
Most programs will show you a description of the USB device that created the port. To verify that your driver is working, you can use a serial terminal, Arduino IDE, device manager, or command line.
Serial Terminal
Look for the port associated with CH340.
Arduino IDE Ports
If you're using the Arduino IDE, figuring out which COM port is the one you want is more difficult. Here's the quick way to figure it out: attach the Serial Basic to your computer, and check which COM ports are listed. In the image below, we have two ports. Now close the Tool menu by clicking on the main Arduino IDE window.
Unplug the Serial Basic, and re-open the Tools->Ports submenu. You will see one of the serial ports is missing. That's the one you want! Plug your Serial Basic back in, and use that COM port.
Windows: Device Manager
You can also verify that the board is installed if it shows up in your device manager. You can click the Start or ⊞ (Windows) button and type 'device' to quickly search for the application. (*On Windows 10, the quick search function is picky on the spelling of the application you are searching for. For example, you may get results using '_devi_' and none for '_device_'.)

Mac OSX: Command Line
To verify on a Mac via the command line. To open a command line window, head to your Applications folder, Utilities folder, then double-click on Terminal. Otherwise, press ⌘ (Command) + space bar (Space Bar) to launch Spotlight and type 'Terminal,' then double-click the search result.
Run the following command 'ls /dev/cu*
' in a Terminal and check for the following changes (your board may show up under a different device name).
You should get something similar as shown in the image below.

You should get something similar as shown in the image below.

Drivers If You Need Them
The driver should automatically install on most operating systems. However, there is a wide range of operating systems out there. You may need to install drivers the first time you connect the chip to your computer's USB port or when there are operating system updates. For more information, check out our How to Install CH340 Drivers Tutorial.

Resources and Going Further
Once you've got serial communication working, you're ready to start playing with serial projects. Consider connecting to a GPS module like the LS20031 (one of my favorites) and watching the serial strings roll by. Or, you can use the Serial Basic to program and debug devices like the Arduino Pro Mini. There are tons of devices that use serial to communicate, so go explore!

I unfortunately didn't get past the turret swapping section in the first level, i'm unsure whether that is a bug, but as '4 levels' is mentioned in your description, i assume that it is something of the sort.
But even without reaching that far, there is definitely a great foundation to this game. I'll get into what i think was done greatly, and what i think could be improved upon.
Firstly, the look is great, i'm unfamiliar on stock graphics or skins in the unity engine, so i don't know whether these are made or not; but the games looks pretty decent considering. I found the game to be running pretty smoothly, a little jumpy, but i believe that it's on my end more so than a fault with the game. The controls are nice and the use of narration to guide the player in the beginning is very much appreciated. I feel that as far as games, and game prototypes go, it is extremely well done; especially comparatively with other beta/prototype games I've played.
That all out of the way, i'll mention some improvements that i could see needing fixing; I hope that with the current amount of experience of my game that i am accurate with some of these things, if not, please feel free to disregard and/or message me.
VOICE: I understand based off of your previous response that your voice choice was one made due to team inability and price; completely fair, but that being said, i would say that the voice lacks some human features that would be appreciated (mainly flexion and pausing) that i would say are a tad disadvantageous for your game; I would suggest maybe downloading a simple voice modifyer online and using it on one of the students voices to accommodate the desired robotic effect, while also implementing a more human and natural tone to it.
MUSIC: I found that the music, while nice, was quite jarring for me personally; the guitar riff (i assume it changes, but i cannot tell what the next track would be) to me was a poor choice, as i feel that (with regards to the robotic voice, and spaceship) the vibe you're attempting to set is a space expedition gone wrong; so sci-fi music (techno type) or maybe some less mellow BGM would really help, especially with that first level. The SFX seemed alright, though i heard no SFX for the turrets, which definitely need to be implemented, as i had half my health gone before realizing that there was another turret behind me.
STORY/PLOT: I love that you've provided one, I really appreciate it, however the implementation of it was rather dull and in my opinion, quite hurtful to the game. The long (though skipable) cutscene at the beginning where it hits you with a barrage of exposition is quite a poor choice in my opinion. I believe that implementing a feed of information drawn out through the levels over a speaker, note and audio recordings would be possibly more effective, and would help give the player a goal for exploring levels; as it sort of throws that beginning 'this is why you are here' speech, i found myself wondering why it wasn't instead used as a fill in during the quiet moments of the tutorial.
Overall, i really enjoyed your game, i don't want you to think i had a bad impression of your game, despite my short experience with it, i felt that it was definitely headed in the right direction, and had a lot of passion that is generally unseen in many prototypes i've seen. I loved the teleport game mechanics, and was impressed with how the game came across for a majority of it.
