So Ive been trying for a couple days to get these 2 actuators working through the relay using an external power source, thats not a problem but because the Lipo is 3.7V and the actuators are 12V I have a DC regulator that boosts the voltage from the Lipo up to 12 but I cant seem to get it all working.
The actuators are 12V Lipo is 3.7V the relay can have input of 3.5 to around 12 I think and the regulator takes in minimum 2V and outputs 12V
The relay is connected properly to the arduino that I got, the middle pins on the relay are the commons, top is normally open and bottom is normally closed. I have the voltage from the battery stepped up before it reaches the relay but regulator only has 3 pins; Vin, Vout and ground so I split the V out to go back to the actuators, this is where i get confused I dont know where the normally open pins on the relay come into play. Any help?
