I have a very viable and useful project for which there is no commercial alternative that I am aware of. My father has parkinson's disease and needs to take medicine every four hours (at a minimum). The meds are different at every dose (8am, 12pm and 4pm) and sometimes he takes the wrong pills from the wrong compartments.
I was planning to build an organizer with 21 LED's. 7 days x 3 doses per day.
I'll use a DS1307 and DS18B20 (just for good measure). I'll have a 4x20 LCD which will display a message:
Saturday 1:55pm
next dose at 7:00pm
At each dose, the LCD will display a message:
Take your Saturday 7PM
Medicine
Also, an LED will light next to the compartment for that day and time.
I will also sound an alarm (via piezo speaker).
I will also need a button to cancel the alarm and mute the speaker. The LED will stay lit until the button is pressed. Processor will be 20x2.
There is enough code on these forums for me to figure out the clock display and alarm function. For now, I want to verify the LED matrix schematic.
I've modified Marks' excellent clock circuits accordingly. In my schematic, I've left out the download circuit, real time clock, and temp sensor.
Please let me know if i've done anything silly.
