So i am trying to use an arduino micro to switch a 24V solenoid, i am using a LM2557 DC-DC step up converter to boost the output of the arduino. (see link)http://www.sainsmart.com/lm2577-dc-dc-step-up-power-converter-module-arduino.html
everything is fine until i hook up the solenoid, when i hook it up the out put from the arduino drops to 2.5V and the output across the step up converter holds at 4V. this could be because the solenoid draws 3.0 W (.125 amps) which the arduino does not put out. also i'm sure amps are lost as i step up the voltage.
i'm wondering if there is a way to boost the output current of the arduino? or there is there another way of making this work?
or should i try suing a relay or some other collection of components?
