| − | == Optic Dispenser ==
| + | Moved to: [[Project:BarBot/Components/Optic Dispenser]] |
| − | | |
| − | ===General Description===
| |
| − | The optic dispenser pours a unit of alcohol (i.e. 25 ml) for each dispensing operation. Commercial optic measures are use for this, driven by a servo.
| |
| − | | |
| − | ===Mounting & hardware===
| |
| − | Servo is attached to plate which is mounted at the normal to the optic mounting board. Hardware:
| |
| − | * 4 x 30mm M3 machine screw
| |
| − | * 4 x M3 locknut
| |
| − | * self-adhesive cable clip or P-clip w/ small self taping wood screw
| |
| − | * string / cable
| |
| − | * quick release cable clip (for when we need to change the bottle)? (to be designed!)
| |
| − | * High torque servo (see Daniel's purchases on [[BarBot/Purchases and expenditure]] page)
| |
| − | | |
| − | ===Logical===
| |
| − | *[boot]Sends message: "ready"
| |
| − | *Receives message: "dispense".
| |
| − | *Uses servo to open value
| |
| − | *Pause enough time for pouring of drink
| |
| − | *Returns servo to closed value position
| |
| − | *Sends message: "done"
| |
| − | *Pause long enough to refill optic chamber before accepting second dispense signal
| |
| − | *Sends message: "ready"
| |
| − | | |
| − | ===Connections===
| |
| − | No integral arduino in optic dispenser - is controlled by central Arduino directly.
| |
| − | *1 x PWM pin from Arduino
| |
| − | *+5VDC from external supply
| |
| − | *Common ground (Arduino & external supply)
| |
| − | | |
| − | ===Power===
| |
| − | Only control from Arduino directly - power comes from external 5V supply which can deliver more current (PC power supply?)
| |
| − | | |
| − | ===Bling===
| |
| − | LED shining into the optic chamber / bottle would look good.
| |
| − | | |
| − | Would require:
| |
| − | * Arduino ground
| |
| − | * Arduino digital output pin
