Clock and Kitchen timer

Description
This project is an easy-to-operate clock and kitchen timer built from standard, readily available components.
The primary function is the kitchen timer. The timer is activated by pressing the rotary knob once. You then set the desired time by turning the knob, or leave the preset value unchanged. Press the knob again to confirm the selection and start the countdown. When the set time has elapsed, the alarm sounds and can be stopped by pressing the rotary knob.
A second objective of this project was to explore how easy it would be to design the enclosure using Autodesk Fusion 360, which is available free of charge for non-commercial use. I found both the quality of the software and the wealth of online documentation and tutorials to be excellent.
In practice, designing the case turned out to be straightforward. One particularly useful feature is the ability to assemble and “join” components within the model, including PCBs and knobs, to verify fit and alignment before manufacturing. I am definitely a fan of this high-quality design tool. See the diagram above.
The software of the Clock / Kitchen timer includes other features, such as:
- An alarm time
- Stopwatch
- Dark mode
- Ability to show messages
- Ability to show birthday wishes (etc....)
The software is included in the ZIP file, which you can download by the link below.
Feel free to adapt it to your needs. Ideas:
- Extend it with a Bluetooth or WiFi module to be able to send messages to the clock display.
- Extend it with an LDR and tune the LDC.
- Extend it with speech. Tip: DY-SV19R Speech module.
- Extend it with better quality audio for alarms.

The build manual describes the components required to build the clock, including the 3D-printed parts, CPU, RTC module, and supporting hardware. It also explains how to set up the Arduino IDE, configure the software, and program the CPU board. A user guide and detailed information about the hardware shields are included.
