Re: what are people doing?
Would anyone like to share some interesting, but very really interesting, projects here?
Here is mine:
A "rich" guy found me to have an invitation card with LCD screen and RTC Chip.
Circuit had two lithium ion batteries, 4x16 LCD, DS1302, 16F628A, and a reed switch.
The name & surname of the invited guest is sent by PC software and written to EEPROM.
A message also sent by PC and written to EEPROM.
The date of the wedding is also sent by PC.
Current date & time also sent by PC and DS1302 is set.
When the flap of the invitation letter is opened, the reed switch releases, and PIC wakes up, powers LCD, screens the name, middle name, last name...
then screens the message private to the specific guest.
then counts down the time to the wedding date and time.
(The code for counting down routine between two dates up to the seconds was a pain).
if the flap is open for more then 10minutes, PIC sleeps.
If the date passes, and flap is opened again and there is still enough battery power, it screens the elapsed date & time and a second message.
What is yours?
