Hi I’m relaunching this thread because I bought everything I need to make it and I built my BIG BUTTON sequencer which works pretty well for the moment! To control the solenoids I used relays that are controlled by the outputs of the sequencer.
The problem I have is the following:
my relays are working properly but when I try to control them with the sequencer they don’t want to play their role.
They are relays mounted on a small PCB with two LEDs: one for the voltage indicator and another one for the CV input of the coil.
The one for the CV input flashes but the relay is always closed (I wired it so that when there is no input it is open and doesn’t let the current flow). So I checked the input voltage and I get about 4v when the sequencer does nothing. I don’t understand why I get 4v… I thought that it must be in the code of the ARDUINO that I had to replace some LOW by HIGH and vice versa…
could someone help me to solve this problem ?
thank you very much
