Project 3 out of 4
Construct a functional Digital Clock using an RTC module. Add an alarm to stay on time.Order Now
We use digital clocks every day, but have you ever wondered how they can keep track of the time, even when they’re not on? In this Challenger project, you’ll turn your Creation Crate box into a functional Digital Clock and learn about the electronic components that allow us to always know what time it is. You’ll set up and wire a Real-Time Clock (RTC) module and a seven-segment LED display. Once all of your hardware is assembled, you’ll write the code that will make it run. For the software portion of this project, you’ll discover many new concepts and commands, learning how to make the code shorter with functions. Once your Digital Clock is complete, take these useful skills and apply them to the challenge exercises.
What you'll receive in the Digital Clock project kit:
Mini Transparent Breadboard
Real Time Clock Module (DS3231)
Double-Sided Tape Squares (2)
M-M Jumper Wires: 10cm (4)
M-M Jumper Wires: 20cm (2)
M-F Jumper Wires: 10cm (4)
M-F Jumper Wires: 10cm (1)
Unlock new concepts and skills as you learn how to make a common electronic device.
Advanced Electronic Components. Discover “backpack” modules and Seven-Segment displays.
Complex Circuitry. Follow along with step-by-step diagrams to wire the hardware.
Intermediate C++. Write code using libraries, functions and two-wire communication (I2C).
Finish building your Digital Clock project and then apply what you’ve learned to complete these challenge exercises:
