so , just bought some pre-bootloaded ATmega328(p/pu) to which I need to upload sketches on a breadboard using uno TX and RX pin as FTDI
Here is what I am to do.
I connected Uno GND and Reset .
Arduino Tx to Standalone Atmega Tx
Arduino Rx to Standalone Atmegaa Rx
Connected Crystal , capacitor to standalone pin 9, 10 (XTAL) then grounded it with 2 coupling capacitor.
Standalone vcc to arduino 5v Standalone GND to Uno GND
Is it possible to do what I need to or i need to buy some USB to TTL devices from the Amazon again?
Thanks for your precious time...
