Introduction: Create Yourself a Clock With Temperature Sensor, Battery Sensor and Alarm
This weekend I have made myself a clock with battery sensor, temperature sensor and alarm,
I'm using ATMEGA128 for it.
Let's get started
Step 1: The Components I Used
I used this components to build my clock :
2. LCD 16x2
4, Some buttons
6. I made myself a PCB, if you need one just contact me,
I have some spares for creating this project.
Now let's continue on the code....
Step 2: The Code for This Experiment
The main code for this experiment is the eeprom,
we need to write and read eeprom on atmega to set the alarm
I give the main idea for it :
if (alarm_minute >= 60)
alarm_minute = 0;
eeprom_update_byte (&minute_ee, alarm_minute );
state_var = SET_ALARM_MINUTE;
next step, let's watch my experiment .....
Step 3: Enjoy the Video Mates !.....
I set the alarm to run for 1 minute....
Till the next experiment..
