Hi
I am Nitish and I am a novice in Arduino I am developing IOT based water level indicator system using the Blynk app, proteus, and Arduino IDE I am facing the issue of the programmer not responding I am using Arduino Uno, port COM3 and the programmer is AVRISP.mll
Any help would be appreciated
thanks
Any particular reason for using a programmer rather than the USB connection ?
When Uploading code, the Programmer is not used. That only comes into play when a Programmes is connected to the ICSP header, or ICSP pins.
Usually that message indicates the Bootloader code in the processor is not talking to the serial port.
If you open Tools:Board, and Tools:Port, does your Arduino appear?
My PC shows COM3 even with nothing plugged in to the USB port, so that is not valid choice for an Arduino for me.
