− | == 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
