Set up as follows:
29
30
- a PC fan is wired up to the 12V supply.
31
32
- the fan's SENSE (tachiometer) pin is connected to pin 2 on the
33
arduino.
34
35
- the pins 4 to 13 on the arduino should directly drive an LED (the
36
LED on pin 4 is in the centre of the clock face and the LED on pin
37
13 is at the outside.
38
39
- if a longer hand (and a larger clock face) is desired, pin 4 can
40
be used to indirectly drive (via a MOSFET) multiple LEDs which
41
turn on and off in unison in the centre of the clock.
42
43
- a button should be attached to pin 3 that grounds it when pressed.
44
45
Implementation details:
46
47
- the timing of the drawing of the clock face is recalculated with
48
every rotation of the propeller (for maximum update speed).
49
50
- pressing the button cycles between display modes
51
52
- holding down the button for 2 seconds enters "set time" mode. In
53
this mode, the fan must be held still and the LEDs will indicate
54
what number is being entered for each time digit. Pressing the
55
button increments the current digit. Holding it down moves to the
56
next digit (or leaves "set time" mode when there are no more). In
57
order, the digits (with accepted values) are: hours-tens (0 to 2),
58
hours-ones (0 to 9), minutes-tens (0 to 5), minutes-ones (0 to 9).
27
Set up:
28
29
* a PC fan is wired up to a 12V power supply
30
31
* the fan's SENSE (tachiometer) pin connected to pin 2 on the
32
arduino.
33
34
* the pins 4 to 13 on the arduino should directly drive an LED (the
35
LED on pin 4 is in the centre of the clock face and the LED on pin
36
13 is at the outside.
37
38
* if a longer hand (and a larger clock face) is desired, pin 4 can be
39
used to indirectly drive a transistor which in turn drives several
40
LEDs that turn on anf off in unison in the centre of the clock.
41
42
* a button should be attached to pin 3 that grounds it when pressed.
43
44
* A DS1307 remote clock is connected via I2C on analog pins 4 and 5.
45
46
Implementation details:
47
48
* for a schematic, see ../project/propeller-clock.sch.
49
50
* the timing of the drawing of the clock face is recalculated with
51
every rotation of the propeller.
52
53
* a PC fan actually sends 2 tachiometer pulses per revolution, so the
54
software skips every other one. This means that the clock may
55
appear upside-down if started with the propeller in the wrong
56
position. You will need to experiment to dicsover the position that
57
the propeller must be in when starting the clock.
58
59
Usage instructions:
60
61
* pressing the button cycles between variations of the current
62
display mode.
63
64
* pressing and holding the button for a second cycles between display
65
modes (e.g., analogue and digital).
66
67
* pressing and holding the button for 5 seconds enters "time set"
68
mode. In this mode, the following applies:
69
- the field that is being set flashes
70
- pressing the button increments the field currently being set
71
- pressing and holding the button for a second cycles through the
72
fields that can be set
73
- pressing and holding the button for 5 seconds sets the time and
74
exits "time set" mode
