I'm building a robot with the Raspberry Pi 3 and I have 2 small 3-6v DC motors with wheels hooked up to an H Bridge Motor Drive Controller (powered separately with a 9 volt battery) and I also want to be able to have the robot see around itself as its driving with the motors, whether this is with 3 separate range sensors or one range sensor on a micro servo motor. I've done some research but I haven,t been able to come up with a definite answer, so are either of these options available? Which would be better / more efficient? I'm pretty new to circuits like these so thanks for all the help!
Here are the parts I'm using -
H Bridge - https://www.amazon.com/gp/product/B01M2 ... UTF8&psc=1
Range Sensor - https://www.amazon.com/IIVVERR-Ultrason ... =hi&sr=1-5
Servo motor - https://www.amazon.com/Muluo-10PCS-Heli ... =hi&sr=1-3
Motors (only using 2) - https://www.amazon.com/gp/product/B07DQ ... UTF8&psc=1
Thanks for all the help!
