Arduino Uno2.4” TFT LCD display Shield9V Battery.Before we actually dive into the project it is important to know, how this 2.4” TFT LCD Moduleworks and what are the types present in it. Let us take a look at the pinouts of this 2.4” TFT LCD screen module. As you can see there are 28 pins which will perfectly fit into any Arduino Uno / Arduino Mega Board. A small classification of these pins is g...
If you planning to use the touch screen function of your TFT LCD module, then you have to calibrate it to make it work properly. A LCD screen without calibration might work unlikely, for instance you might touch at one place and the TFT might respond for a touch at some other place. These calibrations results will not be similar for all boards and ...
The 2.4” TFT LCD screen is a perfect Arduino Shield. You can directly push the LCD screen on top of the Arduino Uno and it will perfectly match with the pins and slid in through. However, as matters of safety cover the Programming terminal of your Arduino UNO with a small insulation tape, just in case if the terminal comes in contact with your TFT ...
We are using the SPFD5408 Library to get this arduino calculator codeworking. This is a modified library of Adafruit and can work seamlessly with our LCD TFT Module. You can check the complete program at the end of this Article. Note:It is very important for you to install this library in your Arduino IDE or this program to compile without any erro...
The working of this Arduino Touch Screen Calculatoris simple. You have to upload the below given code on your Arduino and fire it up. You get the calculator displayed on your LCD screen. Now, you can enter any number and perform your calculations. It is limited to only two operand and only operator for now. But, you can tweak the code to make it ha...
