Hi @Geethesh, If you are building simple POC (Proof of concept ) or Quick prototype then the HC-05 is enough with the ATtiny.
- For the ATtiny45 minimum circuit you only need one Pull up resistor for Reset, and one Filter capacitor between VCC and ground and you also need to populate ICSP pins for programming
- You also need only two external componts HC-05 and Buzzer .
- In the this project we did't require any external oscillator , the internal 8mhz should be fine .

@Geethesh , keep in mind ATtiny series doesn't have Hardware Serial, so you should use the SoftwareSerial for that you also need two more for UART communication (Rx, Tx) between Arduino and Bluetooth.

@Geethesh In case if you live near kalamassery(where Fablab is situated) I strongly suggest to go to Fablab where you can find all the necessary tools and IC's required.

Did anyone use Arduino Portenta H7 with Arduino IOT Cloud? It is listed on IOT Cloud Page but it's not supporting!

When I was trying to connect the board with the, it says The device found is not compatible

But it's listed in the supporting board page.

also mentioned in the portenta page .
