16  Using Arduino / Installation & Troubleshooting / Arduino error on: March 25, 2013, 05:52:00 am
Hello.. I am new to arduino. I m using arduino duemilanove. I recently came across an error. it says "avrdude: stk500_getsync(): not in sync: resp=0x00" and i cnt seem 2 figure out whats the problem. I may need some assistance please.

hey thanks.. but is there a schematic for the whole design.. for an example, i found this in google.... If i use this and create a block later simulate it with an rectifier, can i get my desired output?

Hello everyone.. I am doing my final year project and I have to do a software simulation for my final year project. My project is design and developing a SCR gate controller circuit. And I am using arduino duemilanove to accept the interrupt signal from the zero crossing detector and send the firing pulse to the SCR in a H bridge rectifier. I am required to do simulation before I can proceed in the hardware. Currently I am using PSIM. I came across the schematic of the device which is way to complicated. Can I get any sort of schematic diagram for the arduino or any other idea on which is the better software that might in associate with Arduino. Any assistance will be much appreciated.....

Is there a tutorial for it?

Hello.. I m practically new to arduino. I m doing a project about controlling a phase of SCR's in H bridge rectifier. I have to design on how to control the firing angle of the SCR. Based on my review, i have to produce pulse using the arduino and interupt signal from a zero crossing detector. From the slow learning, i m trying to use the PWM pulse to trigger the gate. But i cant seem to have an idea on how to vary the firing angle where the pulse trigger the SCR. Example, If i set the firing angle to be 45 degree, the pulse from arduino after receiving the interupt signal, start producing pulse on the 45 degree. Can someone show me some examples perhaps.
