I purchased some devices on ebay from a seller in China. One of the devices was a USB to RS232 converter which uses the FTDI FT232RL chip. When I plugged it in the drivers did not load for it. After a few emails from FTDI support, it turns out that the FTDI chip on the device was a fake. So I did some research and with the help of fellow forum members at www.electronicspoint.com, was able to unbrick my devices that used the fake FTDI chips.
Follow the instructions in this youtube video to get the drivers to work. I recommend going to device manager and right clicking on the device which should have a yellow exclamation point then select uninstall. Also check the box to delete the drivers.
I learned a lesson when purchasing hardware from ebay. Make sure what you are getting has genuine equipment. Clones are ok but when you have trouble, you are usually stuck with a piece of junk. I recently bought an arduino pro mini clone that came with a usb to serial converter which has an FT232RL chip from ftdichip.com. I plugged the adapter into my usb port and the drivers did not load for it. After a few days of research, I contacted ftdi support and sent them a screen shot of their usb view software and they confirmed that the device indeed has a NON-GENUINE ftdi chip.
I purchased a nano clone from amazon.com from phantom yo-yo. I used it a few times and had great luck with it. Then over the weekend it stopped working. The same issue here, fake ftdi chips. Money wasted. Here is the one I purchased: http://www.amazon.com/gp/product/B00ALDKOX4/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
If you are concerned with your FTDI hardware, send them a screen shot of the usb view to firstname.lastname@example.org. They will respond promptly.
Wanted to do something with Halloween decor this year using an Arduino. I found these rats at Dollar Tree and thought they would be cool with some LEDs in the eyes. I used two 3mm green LEDs (was all I had in this size). I modified the blink sketch and loaded into my UNO then…IT’S ALIVE! IT’S ALIVE!
