TX-RX Capacitive Sensing

Using Neil Gershenfeld's hello.txrx.45 codes, this project demonstrates how to use miniature copper tape electrodes connected to the pins of an ATTiny45 to create a capacitive sensor that can detect proximity and contact. I modified his txrx.py output file to average the filtered sensor values for a settling value, then compare it to incoming data and print if something was too close, or if something was touching.
