Relays
For this iteration of the Drinkmotizer, I am using 10 relays off of a SainSmart relay board. Six for the drink module actuators and four for the chaser station.
Each bottle module uses a 12VDC car door lock actuator. When activated, the draw spikes to 12V @ 5A. So, depending if I want a full shot or a partial, I activate the relay time accordingly.
The chaser station operates differently. The chaser bottles are pressurized by a paintball gun tank. What stops the chaser fluids from spraying everywhere are four solenoid valves. Then one valve is actuated, it opens, allowing the pressure to push fluid through the solenoid. For the record, the solenoid is designed for fluids.
