I’ve been wanting to make my own alarm clock for some time now, since I’m unsatisfied with any alarm clock on the market (neglecting overpriced ones). I just made a quick prototype to see if I liked it or not.
Sanguino from Moderndevice
20x4 LCD from Moderndevice
Electronic brick real time clock module from Seedstudio
Electronic brick temperature sensor from Seeedstudio
Electronic brick fully buckled 4 wire cable from Seedstudio
Electronic brick fully buckled 3 wire cable from Seedstduio
Dual-female jumper wires from Seedstudio
1k trimpot for contrast adjustment
I also used a USB BUB Board from Moderndevice to program the Sanguino. I have to say, I really LOVE these two companies. They have great products at great prices, and their tech support is phenomenal (I’ve had to use them both).
There is no alarm code inside the source. I was merely just testing to see if I would like the setup or not.
In my real design, I don’t think I want to use a 20x4 character LCD as it is very hard to tell the time from a distance. I’ll be looking into either a monochrome graphic LCD or a color LCD.
Feel free to leave a comment if you have any questions.
