Questions & Answers

When it comes to LCD screens, what is the ?

This sphere measures 58 x 80

Do you know whether the Arduino Mega will work with this?

In order to accommodate the Arduino Mega, it has a larger number of I/O pins available.

Would you be able to interface with the spi pins (sck, mo, mi) as usual?

Pins 4 and 5 serve as digital inputs on the shield You can still use SPI without the use of Pin 10 of the Arduino. Pin 10 of the Arduino is SPI/SS, so as long as you don't need it you can connect. There are three main SPI pins (11, 12 and 13) that are accessible on the

Selected User Reviews For DFROBOT Gravity: 1602 LCD Keypad Shield For Arduino

What do you think of the addition overall? I should conduct my review before I submit it Because I have very little experience with Arduino and this may have some effect on my outcome, I am concerned about how this will impact the final results! With additional libraries installed, I was able to make the demo program scroll from 0 to 1 You have to cross the top line nine times and then the bottom line nine times to complete it

4/5

As I played around with it (sketch), I was able to modify the program into displaying a message, but it was not very crisp. It was impossible for me to get the lines at the top and bottom to scroll or to align. It's hard to understand how these modules work from their documentation at best, and you have to bashing your head against them in order to figure it out. It assumes that all that needs to be known is represented by the example that is provided, which does not introduce the code. Having said that, I am still very much a beginner, so maybe after a few years of programming, I won't find it so difficult. A strong YouTube channel will be necessary to help you further learn about quick-to-market.

The Nucleo F401RE is compatible with this accessory

5/5

I'm impressed with the quality of the material. Silkscreen is crisp, and the soldering is excellent. This doesn't seem to be a problem for LCD. There is no logic level 3 for this sentence. Each of the buttons is readable with its own analog value, and the reset button also works. The TextLCD library can be used with mbed OS 5 and mbed OS 5. Because the Nucleo is 5v tolerant on all its pins, it can be used without a level converter to drive the 5v vcc breakouts. The mbed ecosystem has a more Arduino-compatible ARM board than the Due or Zero, which is kind of ironic.

You won't need to surface mount if you use this

5/5

This little display is great. One analog button serves as a button for the display and six digital buttons serve as the buttons for the display. In my case, it is surface mounted without drilling holes in the enclosure due to the pins soldered to the top of the board. I had to cut the pins off to get it to surface mount. This way, there are no holes in the enclosure. In some cases, it may be better to leave them off and/or provide the user with the components.

The product is as advertised and works well Well built, only the pins need a little more length to make them useful

5/5

There is no doubt that this shield lives up to expectations. The system is easy to integrate into a project, and it performs A great deal of care and attention has been put into the design. It will be noted that the header pins for stacking are quite short, which makes stacking with another shield, such as an Ethernet shield, a challenge. By inserting a second set of stacking headers between them, this problem can be resolved When ordering, make sure you order these at the same time if you plan to use this on anything other than the Arduino bare-bones.

It is a prototype universal

5/5

As a shield, it will enable me to develop the code for my existing project but can also be used as a breadboard to develop sketches before committing to an actual schematic.

At a great price, you can have a great LCD and keypad

5/5

According to the description, the product is exactly as described. LCD display with two 16' heights and sixteen 16' widths I was able to set up the software from the web and it works!.

Right out of the box, it works perfectly

5/5

The standard Arduino liquid crystal library integrates really well with this It took me just a few minutes to put together a program that displays text and handles button presses.
