First off I love the hardware, but have hit a bit of a snag in the capabilities. For one of my prospective projects it involves interfacing with existing hardware it uses pwm to control motor speed via, an inverter motor shield using ac wall power, this next part is where hardware is falling short and Google doesn't seem to hold the answer the unit requires greater pwm voltage range than the ardrunio can provide 3-6 volt signal, so I ask for guidance on how I might build a circuit or if someone knows of a shield that expands pwm voltage range I'm stalled hoping for advice
Can you please post a copy of your idea, in CAD or a picture of a hand drawn circuit in jpg, png?
Any links to data on parts you are looking at would help as well.
The arduino can provide PWM output at 5Vdc, you can by using transistors/MOSFETs use the 5V PWM to produce higher voltage PWM.
What model Arduino are you using?
