Water delivery function inverted
#1
Hi,

I'm having this problem with water delivery where the valve function is inverted: When the valve button on the bpod console is on (green) water doesn't flow through the valves, and when its off (red) water starts flowing. I have made sure to check that it is not a hardware problem; i've switched the valves, tried different green boards and even tried swapping the bpod machines, but the issue persists. Please let me know if anybody has encountered a similar problem or has ideas on what can be going on?

Thank you!!

Hi Veronica,

What kind of valves are you using?
Some valves are designated NC (Normally Closed) or NO (Normally open). For liquid dispensing, you need an NC type valve.
