All the pins are used! How can I connect anything to the Arduino??

All the pins are used! How can I connect anything to the Arduino??

We suggest using a protoshield (with stacking headers) or a proto-screwshield to access the unused pins (2, 3, and analog 4 and 5). You can connect various i2c sensors or analog sensors to analog 4&5. You can also connect an i2c port expander to get more I/O pins. If you desperately need more pins, and you're careful, you can use the 8 datapins while the TFT isn't being written to - they are high-z and unused as long as the WR and RD pins are high
