In the IDE, go to File/Examples/Basics/Blink and load the sketch. If you have performed the previous steps correctly, the IDE should be able to communicate with the Arduino and upload the sketch. Eventually you will see LED 13 (on the board, blue) flashing once per second. Blue LED on board flashes once per second (with “blink” sketch) But it doesn’t end here! That’s were the Power Cutter comes in. Thanks to Talpa PCB retrace of the BTE13-010 I was able to elaborate an evil power saving plan: Before connecting the Serial – USB converter, make sure that the switch is positioned on the appropriate voltage value which can be 3.3V or 5V depending on the model of your Arduino. Ours works at 5V and 3.3V interchangeably.

The analogue header doesn’t fit because of the reset button. Use sandpaper to make the analogue header thinner. Arduino clones need specific drivers, different from the standard ones that come with the Arduino IDE Simply put…the computer is not even seeing anything plugged into the comm port. trying to do any more communication is pointlesss. Like not getting a dial tone on a phone…trying to continually dial out is an effort in futility. Then I saw level shifter like a TXB0104 - would that be something where I could simply connect RX/TX/VCC/GND on both sides and turn my brain off?Turns out that the driver isn’t signed and in Yosemite, driver files must be signed to be used. There’s a command we can issue to bypass this. Our sketch is based on the one found by default on the IDE and which is called “Sweep”, with the addition of a 16×2 LCD display that shows the value of the rotation angle of the servo. Basically, it rotates the servo and shows how much it rotated on the display.

Before starting, we specify that this tutorial can be used to learn how to install the drivers of the CH340G module (Serial – USB converter), on which the communication between the Arduino mini and the PC is based. So my first idea was to buy a (maybe isolated) USB adapter and putting it in a heavy enclosure with a selection switch that makes it very obvious the voltage was. In the attached CH341SER_LINUX.ZIP file, there is a file called readme.txt which contains the detail of all the steps to follow. Note that these drivers support a kernel version from 2.6.65 to 3.13.x.As long as your computer can see other devices plugged into the same USB port and assigns them a comm port number (each number is unique to THAT device) then it is either the cable or the board on the Ortur. You want to use unidirectional voltage level translators or isolators for UART and SPI, and not bidirectional ones, as the latter tend to have glitches (in the low level signal part, when the direction sensing circuitry isn't sure of what is going on) in this kind of use that can cause transmission errors. So, I'd say forget TXB chips, and all bidirectional voltage level conversion chips. Be careful not to connect the TXD terminal of the BTE13-010 with the TXD terminal of the CH340G (or the two RDX terminals)! To find out why, read this clear guide from Sparkfun on serial port operation and connection. As an Arduino-phil I use the ESP8266 Core from GitHub to adapt the Arduino IDE to the ESP8266. It uses a somewhat different tool chain to compile the Arduino C code into binary files executable by the ESP8266, but the Arduino IDE and most libraries are the same. The only stumbling points are: Global variables use 9 bytes (0%) of dynamic memory, leaving 1,015 bytes for local variables. Maximum is 1,024 bytes.

the operation can be made simpler and more precise with the help of a breadboard. Insert the connectors into the breadboard so that they are perfectly vertical and place the Arduino on them the connector to be soldered on the part of the analog inputs is too wide, thin it slightly by rubbing it on sandpaper Soldering headers can be pretty easy if you take advantage of a breadboard. Place them on it and then put Arduino over connectors.While Arduino is placed on the breadboard, only solder the four vertex joints. Why only four vertex? Because breadboard is made of plastic and if you accidentally hit it with your iron solder tip you’ll damage it. WARNING: by installing a new version of the Arduino IDE you risk overwriting the CH340G drivers. For this reason we suggest you not to install the IDE using the executable (.exe) but to use a “portable” version. If you accidentally overwrite the CH340G drivers, uninstall the IDE with the drivers and reinstall everything from scratch.

I would stay with Laser GRBL open for testing until you can establish connections with it since to me it is easier to work in for diagnostics. Once LAser Grbl can comm with the laser and comp then you can swap over to LB.

Recommendations

As said you can try rebooting your computer and see if that helps…I never had to myself for my diode laser but…I have had to for other driver installs so…can’t hurt. Computers are funny things. I wanted to hide the USB serial and USB sound dongles in the box so I looked through my junk box for a USB Hub. I found a 4 port hub so I decided to add a USB memory key. Look at the Fritzing diagram above or follow the instructions below to connect the Arduino mini clone to the Serial to USB converter: BTE13-010--------------CH340G I have also found that these drivers work fine when connecting the LoLin NodeMCU V3 to my Windows 7 PC (I had to do nothing, since I had already loaded the drivers for my cheap Chinese Arduino Nano clones). I suspect the same will be true for the Amica v0.9 (yellow or blue PCB) NodeMCUs (both considered out-dated) and the DoIt/SmartArduino brand NodeMCU V2. Both of these boards also use a WCH CH340G USB-to-UART bridge chip. If you buy your own FTDI chip, go for something that has two serial ports, e.g. FTDI FT2232H, those are often used as JTAG interface with an additional serial port, too.
