A quick Lego rover using the Mindstorms Robotic Invension System 1.5 using native RCX Code. The rover uses an Ultrasonic Proximity sensor coupled to the RCX brick. The Ultrasonic Proximity
The primary problem when designing a sound sensor for a standard ADC input is to convert the amplified sinusoidal waveform into a corresponding stable DC voltage. This circuit here uses
A few years ago, I tried to build a wireless rover using a 40-pin ATMega32 Atmel Microcontroller and an old Nikko R/C Jeep. This was something of a continuation project
