## Questions & Answers

**Q: Does this draw any power when switched off?**
A: I guess it will draw few mA for 555 timer.

**Q: does this controller work in forward/reverse mode?**
A: no, not specifically.  For most types of DC motors, you could use an appropriately rated switch (DPDT rated for more than the amperage of the motor) to reverse polarity, and thus direction easily enough...

**Q: will this work on a car heater fan?**
A: No. It is not meant for that.

**Q: will this work as a dimmer for LEDs?**
A: If your leds are 12V DC led strip up to 5 amps,  then yes you can use it as a dimmer. In fact, there is a LED on the board for indication and its brightness shows the PWM duty cycle.
