Atm i am trying to use an arduino with the PWM pins to control an output that can be varied between 1-10v (for laser energy control). having a few issues in getting the circuit correct, and to the 0-10v range.
reason for 1v minimum is laser is not stable below 10%.
I have tried:
- low filter pass with inductor ( only issue is not variable)
- transistor with a 10v supply, using the PWM signal to regulate the supply. (think i may have wrong transistors or not have enough of an understanding to get it just right.
Attached is the low filter pass that uses an inductor to boost the voltage to 0-60v, but i don’t think its what i need (correct me if i’m wrong).
The signal has a max rating of 500mA 0-10VDC.
Thank you in advance for any advice/assistance.
