hi dear friend.
Here I m getting the O/P of MCU 5V. But I want the O/P 2V. How can I control it by program or any other option..
 

the microcontroller will give output same as what ever the supply voltage is.....but if you want 2V output....then u can use a voltage divider configuration.....and if current requirements are high u can use an opamp as a buffer after voltage divider....
 

Thanks for the information. Actualy I also want to generate the sinosoidal wave using MCU. CAn u tell me how this can be happen.
