If Customs Duty is payable to your territory, you"ll be responsible for paying it to the authorities, so SunFounder isn"t involved in this process. Whether Customs Duty is payable, and by how much, depends on a whole lot of different things. For example, many countries have a "low value threshold" below which they do not charge any Customs Duty.

If, for whatever reason, you refuse the customs fee and the parcel is returned back to us. If you"re still unsure on whether you"ll be subject to customs fees, we recommend contacting your local customs office for more info before placing your order!

Well it seems that the issue wasn"t that simple. I believe there is a problem with the actual LCD. I"ve testing the soldering and there doesn"t seem to be an issue with and shorting of pins.

While it did work for a short while using the 4 wires, I still have yet to be able to continually receive a constant working display. All the lights come on. I can get the contrast to work fine but the information doesn"t display (i.e. hello world!).

Is there a specific way of working the LCD? I am going to return this one for a new one (different brand/manufacturer). I basically plug everything into the bb and arduino and then power it up. Sometimes I"ll get the gibberish again, most times I just get a blank screen with boxes that I can manipulate using the contrast.

At the moment I cannot get anything to pop up on the screen, other then lines 1 and 3 showing the completely filled character space (the boxes when I raise the contrast to full), while lines 2 and 4 do not respond. Again, just simple code but nothing.

This is an excellent display. I soldered a header on, then plugged the display into a breadboard connected to an Arduino Uno, and it lit right up. Contrast is adjustable as others have described. Although I am no expert on these things, the connections to the display seem to be the same as the numerous on-line examples which I found. If you are having trouble getting this display working, then I recommend you look on-line for sample code and wiring instructions and have some fun with it.

I am very new to the Photon coming over from Arduino. I am making a RFID scan in system for a project to replace a current system. The RFID integration was super easy and I love the simplicity, the integration of the LCD is not going so well.

Using the LiquidCrystal library and the example project following their pin layout (no i2c chip) and I am not able to get it up and running. They ONLY change I have made is to set the screen size to a 20x4 vs. a 16x2. Even leaving the 16x2 doesn’t work. Screen is lighting up and 10k pot is working just fine… but only first and 3rd line are showing character placement (just boxes).
