Description

I want to add a speaker and meter to a Sparkfun Geiger counter module. I wish they had broke out more pins from the microcontroller. I needed to add some wires to the pins. Here is what I have so far: https://youtu.be/S90JSTjxOEk I toggle the speaker on signal. The meter is connected to a PWM output and has a sum - decay function that adds a value on click and then slowly decreases. I need to add a scale control (low-med-high) so I don't pin the needle. And I need a nice box.

Components

  • 1 × Sparkfun Gieger counter module Seems discontinued :( https://www.sparkfun.com/products/retired/11345
