What is it?

This Teddy Bear with Heart lights up in the dark! Behind the heart are to reverse mounted LED's that can flash in different patterns. A push button is used to turn the pin on and off, and to change to the different patterns. ATtiny412 is used to control the patterns of the LED's. Powered by a 1225 coin cell battery. These can be attached to your backpack, purse or where these as a badge.

Why did you make it?

I always wanted to design some pin/earrings with a valentines theme. Using a bear with heart, instead of just a heart, allowed me to hide the components, like the battery, micro-controller and push button behind the head and paws of the bear. I also wanted to highlight some of the features in the design with immersion gold plating instead of the regular HASL finish.

What makes it special?

The immersion gold plating turned out very well and created a much nicer finish than HASL finish I usually use on the designs. The ATtiny412 is a perfect fit to control the LED's with a PWM output using only the RTC (Real Time Counter). The push button can be used to cycle through the following patterns:

• Single heart beat
• Single breath
• Single flash
• Full heart beat
• Full breath
• Outer flash
• Random Pulse
