HC-SR04 / Parallax Ping / SeeedStudio Ultrasonic Range Sensor support
May 20th, 2014I added a ‘distanceRead()’ function to the RoboPi API and firmware. I expect to release the newer firmware and libraries by the weekend.
Currently it supports the inexpensive HC-SR04 sensor, but I am also adding support for the Parallax Ping and SeeedStudio red sensors.
The HC-SR04 only requires a single RoboPi I/O, and as RoboPi already has a current limiting resistor on the servo header, no need for an external resistor!
Mainly, the reasons are sildenafil samples identical acts on erectile dysfunction, availability in different form, easy obtainability, and ultimately fewer prices. If you are struggling hard to enjoy orgasm after enough sexual arousal then it is definitely a serious sildenafil super active problem for many men. This in turn leads the man to erectile dysfunction. this happens when the enzyme named PDE5 attacks the blood stream and blocks it and prevents it viagra on line steal here from flowing into the direction of penis. This all, has put pressure on men resulting in performance order viagra page anxiety and eventually erectile dysfunction issues.
Works great.
Tomorrow I intend to re-calibrate the “hips” on HexPi, in preparation for re-calibrating all six legs.
