How to power up Pulse Sensor using external battery?
Posted: Fri Feb 12, 2016 5:08 am
After uploading a sketch to my Arduino board using an USB cable to my laptop, I can see my Pulse Sensor board got powered up as the red LED got turned on.
However, once I disconnect my USB cable from my laptop and connect to an external portable battery, this module is off as the red LED doesn't light up.
Is there any setting I need to use with external battery for this module with PSO2 sketch?
Thanks
