I Designed A Custom PCB To Avoid Pressing A Button Three Times
TL;DR
A custom PCB was designed to automate the control of a night light, eliminating the need to press a button multiple times each night. This solution enhances user convenience by ensuring the light starts at the desired intensity.
✦ Why It Matters
Consider designing custom PCBs to enhance the functionality of everyday devices you find inconvenient.
Key Takeaways
- Identify repetitive tasks that can be automated with electronics.
- Explore low-power microcontrollers like the ATtiny85 for similar projects.
- Use PCB design tools like EasyEDA for creating custom circuits.
- Consider safety precautions when working with mains-powered devices.
How It Works
The ATtiny85 microcontroller is programmed to simulate button presses on the night light, using a transistor to short the button's signal leg to ground. This automation allows the light to adjust its brightness without manual input.
