   Not technology related but interesting about bike safety and street planning

Notes, issues, etc.

• The writer of the Arduino playground document claims analog input from the MaxSonar sensors is less accurate than pulse width
• Someone claimed that for the analog output from the sensor noise can be reduced with a capacitor and resistor, I'll have to find the details again though if needed.
