The name 'frog' is from the sensor HC-SR04, the "head" of the robot.. it looks like a frog =P The purpose of this project is to improve the ability of this arduino sketch to avoid obstacles. Anyone ...

HC SR04 ultrasonic sensor library for using on Arduino IDE. The present library is oriented to an specific configuration of the HC-SR04 sensor, the reset option differs from other librarys due to the ...

We don’t know if [Hanna Yatco] has a good sense of balance or not, but we do know her Arduino does. Her build uses the ubiquitous HC-SR04 SONAR sensor and a servo. This is a great use for a ...

According to the datasheet, this ultrasonic transducer’s working frequency is 40 kHz. So, the purpose of using Arduino and this small piece of code is to generate a 40KHz high-frequency oscillation ...
