What time is it? It’s wake up time! This week, we’ll explore the Intel® Galileo Gen 2 board’s real time clock (RTC).
The RTC, once set up, will run even if the board is turned off so long as it gets power from the attached battery. While this is a relatively simple function of the board, it has its obvious uses – scheduling, timing, or calculating intervals.
We will be making a “wake up clock” which will turn on and illuminate the room slowly, simulating a morning sunrise. Hopefully, it will make waking up on Mondays a bit easier.
Here is a list of items you’ll need to make this project:
- Intel® Galileo Gen 2
- Intel® Galileo Gen 2 power supply
- Arduino Protoshield
- LED power supply
- 1 High power white LED(3v 700mA)
- 1 1000 μF Capacitor
- 1 2.1 mm DC jack-to-screw terminal adaptor
- 1 10k potentiometer
- 1 1.8Ohm 2w resistor
- 1 LM317t voltage regulator
- 2 10kOhm resistor
- 1 2n7000 transistor
- 1 Coin battery holder
- Jumper wires
- Colored wire
- Pin header
- 1 8 mm magnet
- Stiff wire (that is attracted to magnets)
- Wood glue
- Hot glue sticks
- 4 mm MDF components – lasercut according to drawing
- Plexiglas components – lasercut according to drawin
- Nuts and bolts
