Practical Robotics in C++ : learn to build autonomous robots. Now available on Amazon in most markets, or the publisher's web store! Viewer/Reader Q&A: What type of power supply did you use in Practical Robotics in C++? If you mean the source/battery, I used a 14.4 volt power tool battery that I had several of. Any would do, but this one is just like it (link to off-brand of the same type). https://amzn.to/3I22Tgw I just used spade connectors, but an adapter like this would be a more elegant way to tap the power https://amzn.to/3WKsX3G If you mean the voltage converter I used to power the Raspberry Pi and sensors, it was this DC to DC converter that steps 14.4 volts down to 5 volts and has a convenient USB connector. https://amzn.to/3Wrr3Fu ###################################################### If you find my videos helpful, you can say thank you and help me to make more tutorials with a cup of coffee or by picking up a copy of Practical Robotics in C++.
