New Product: Octasonic 8 x HC-SR04 Breakout Board

Need to connect up to 8 ultrasonic sensors to an Arduino or other 5V microcontroller? Now you can with the Octasonic HC-SR04 breakout board. This board uses SPI communication so only uses one dedicated pin on the microcontroller. Here’s a video of an electronic piano project using 8 ultrasonic sensors. This would work great in robots for obstacle avoidance too!
