Support

I am new to using the Arduino. I have followed the steps on the instructions up to "3. I added the location of the avrdude executable to my path Path= path=C:\MyDev\arduino-1.8.19\hardware\tools\avr\bin;%path%."

I plugged the UNO back in typed in the "arduino -P com4 -b 19200 -c avr isp -p m328p -v."

I got the following message "'avrdude' is not recognized as an internal or external command,

operable program or batch file."

Any way you can upload a video walking through all of the steps?
