how can i create sine wave with arduino uno (without any components)?
thanks in advance
To get any output from the Arduino, which has no in-built digital to analog converter, you'd probably need a few external components. Say four resistors to make a crude DAC. You also need to make a represtatation of a sine table in code.

ok thanks
what frequency are you generating?
you can generate a sine wave using PWM
do a web search for pwm sine wave or pwm sine wave arduinoand you will get plenty of links

...but it still doesn't meet the requirement of "without any components".
A Due has a true DAC, but doesn't meet the requirement of "arduino uno"
