In circuit diagram 2 what is the value of capacitor and resistor in parallel with triac and AC motor?

 good project

Pleasae provide me link for downloading the source code for this project as one of the two free downloads.

mr Ashutosh Bhatt  

i am univ.student electronic eng.

how can i make 3 phase AC motor speed control ?


can you help me ?


thank you so much for help me 




I noticed the Schematic on tab2 has several bits of info missing or incorrect. the caps behind the motor doesn't have any details and the pins on the IC 89C2051 don't match up with the description. Can you please confirm what is correct. 

Also please don't is P3.1 type indicators as they are confusing. P1 p2 is fine.

details required
