TFT Taphandle

thingiverse

This is a custom tap handle for my homebrew. Design your labels, convert them to 240x320 24-bit BMPs, save them on an SD card, and insert them into the SD card slot built onto the display shield. Browse through the touch screen interface. Note that the resistive touch screen isn't very sensitive, so you won't accidentally switch between labels frequently. However, it does require a power supply of 7-12 volts to function; batteries wouldn't last long enough. You will also need half-inch by #4 screws to assemble the parts, an Arduino (or compatible), a microSD card, and a MCUFriend-compatible display (I used this one https://www.amazon.com/HiLetgo-Display-ILI9341-240X320-Arduino/dp/B0722DPHN6/ref=sr_1_1?dchild=1&keywords=MCUFriend&qid=1589309760&sr=8-1). This project prints in three parts: the back, case, and stem. The Arduino screws onto standoffs on the back, while the stem has threads that require it to be printed with the top facing down. The case is the front/frame. Use #4 screws to attach the back and stem to the case. The Arduino code is a combination of two examples included in the library. Install the MCUFRIEND_kbv library using the Library Manager.
