From the project

electronic circuit for night light

The Spark Night Light is an electronic circuit that turns on an LED in dim lighting conditions.

Below is a simple demonstration of the LED turning on as all ambient lights in the room are turned off.

Spark-Night-Light: common questions

What microcontroller does the Spark-Night-Light use?

The Spark-Night-Light is built around the ATMEGA328P-PU, from the AVR/Arduino family.

How big is the Spark-Night-Light PCB?

The Spark-Night-Light measures 45 × 40 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Spark-Night-Light?

12 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the Spark-Night-Light design files?

From the hollowmaster1496/Spark-Night-Light repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Spark-Night-Light design in my own project?

The repository has no license, so all rights stay with hollowmaster1496. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Spark-Night-Light without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
