Arduino Nano connection error (CH340/CH340G driver)


Recently, I’ve got some cheap Arduino Nano from Internet for about 5 USD. However, I was struggle with the connection issues that my Arduino program cannot regonize my Nano chips.
The error message is kind of like thisScreen Shot 2017-01-08 at 12.44.13 PM
And I found out that the new Arduino nano has a different USB connection chip which is CH340G compared to the previous FTDI one.

The new nano(left) and the old one I bought have some different chip layout.DSC_0292
After installing the driver from the manufacture from China, the problem finally sloved.Screen Shot 2017-01-08 at 12.51.29 PM
You can download the driver from here if you have encounter the same problem.
WCH CH340G driver 
Just click on the download button.

For Mac and Linux I think this two file might work!

Arduino CNC shield control Stepper motor with DRV8825

CNC shield is quite useful for stepper motor driving. Here, I demonstrated how to use simple arduino code to drive stepper motor with DRV8825. First, just simply mount CNC shield onto Arduino Uno. Make sure the direction of the shield was right, where both the USB port and power supply wire was on your left hand site. The blue wire is my power supply which can be connect to 12-36V of power source. Next step you can mount the DRV8825 chip onto the CNC shield. Make sure the DRV8825 chip goes like this direction. If you put the chip in the wrong direction, you will probably damage it. By adjusting the jumber underneath the DRV8825 chip, motors can be driven with different kind of microstepping mode. I put three number here so it means that I set it into 1/32 step driving mode. Which is the most precise  one of DRV8825. The motor can connect to the right site of the DRV8825. Plug in the usb to your computer and upload these coded which will generate...

Can D13 pin of Arduino Uno and nano be use as input pin?

D13 pin can be use as  digital output pin. D13 pin can be use as i nput pin  together with  external pull-up  and  pull-down resistor . It is not recommand to use the  D13 internal pull-up  resistor because instead of the regular 5V, the voltage will be hanging around 1.7V. Most of Arduino newbies have their first code to blink the LED with D13 pin as an output pin. This really give us big confident to know the code can be successfully executed on the microcontroller. However, due to the build-in D13 pin on different Arduino board has slightly different circuit design,  is there any limitation to use the D13 GPIO pin as input pin ? Let’s find out more! Experiment condition I investigate both the value of D13 digital input and LED light status with the following code with  Arduino Uno Rev3 . and  Arduino nano 3.0.  void setup() { pinMode(13, INPUT); Serial.begin(9600); } void loop() ...
