Hi,
went here cause I had an initial issue with my bought circuit, but I had managed to put the BD139 backwards. Then I realized I had another question.
Would like to be able to adjust the speed on the fly for the load connected to the relay without a manual solution. Would be lovely if I could remove the pots and have it all controlled form an external wireless source like an xbee.
The pic16f176 has pwm capabilities, question is, taking advantage if this, would it mean having to break the protection measures put in place, or is there a pwm output I could use?
And yeah I realize I’m lazy for asking instead of just doing it.
