Trying to up-load program from Arduino IDE to the Coffeetronics PID Temperature controller ( Jameco kit part no 2190178), using the Sparkfun FTDI USB cable DEV-09718.
The PID controller board uses ATmega328P-PU with Arduino UNO bootloader.
The Arduino IDE shows the USB serial port as com3, but when trying to upload a simple program ( "blink" ), I get the error message :
AVRDUDE: stk500_recv(1): programmer is not responding.
From the Arduino 1.8.13 IDE tools
board - Arduino UNO
port = com 3
programmer -> Which one should I select ?? I have tried multiple types, but keep getting this same error message.
The programmer makes no difference when uploading code via USB; the pressing of the reset button does the trick. One of the wires in the FTDI cable is the DTR; if you connect that to the Arduino's reset, the reset will be automatic.
I'm still getting compiling errors when trying to use the program for the Jameco PID Temperature controller kit part # 2190178
It's better to start a new thread for that in the Project Guidance or Programming section. It would definitely help if you posted the errors.
