Gemini AI Assistant With Esp32

capture 10.png

As you may have used google's new AI assistant Gemini. A few time ago Gemini's api got out, so this is a project to test the gemini api

why gemini?

  1. there is a controvercy between google's Gemini and open ai's chatGPT while chatGPT has huge popularity it isn't free.
  2. where as gemini is free that means we can ask as many questions as we want.

Supplies

  1. ESP32 dev module
  2. 2.8 nich tft display

Connection

components

here i have used (ili9341) tft display and esp32 dev module

  1. 2.8 inch tft display - (buy)
  2. esp32 dev module -(buy)


2.8 inch tft display --> Esp32

  1. Vcc. ----> 3.3v
  2. Gnd. ----> Gnd
  3. CS. ----> D15
  4. RST. ----> D4
  5. DC. ----> D2
  6. MOSI. ----> D23
  7. SCK. ----> D18
  8. LED. ----> 3.3V
  9. MISO. ----> D19

  4. click on upload.

and there you have the your esp32 runnig Gemini AI.


Hey code is here

Conclusion

you can aks any question using the serial monitor in the IDE press "ctrl+shift+m" keys to open the serial monitor and after it gets connected to network try asking your question
