A simple "Mastermind" clone for the Arduino Uno with 3.5" tft display.
With a random generator created by David Pankhurst
In the Arduino ide, you must install Adafruit_gfx, McuFriend_kbv and the TouchScreen_kbv library.
To do it, download the zip file TouchScreen_kbv (see below) and the code file. Open the Arduino ide, click on sketch->include library->add zip library and select the downloaded lib. Then press Ctrl+Shift+I. Type the name of the also needed library in the search bar and install the libs. Now open the downloaded code file and upload it to your Uno. Thats all, have fun!
