At some point, I’ll be looking to extend my Raspberry Pi robot, and one of the ways to do that is to use I2C (Inter-Integrated Circuit) serial devices. So, in this feature, I look at how to access an Arduino board from the Raspberry Pi using this serial bus. I also include both Raspberry Pi and Arduino code to demonstrate the use of the serial interface. Continue reading “Using I2C Serial Bus to Connect Raspberry Pi to Arduino”
The TB6612FNG Dual H-bridge DC motor driver is ideal for small robot vehicles using the Micro Metal Gearmotors. This guide looks at how to use this driver when connected to Arduino compatible boards using single power supply options. Therefore, review this guide for pinouts and example circuit diagrams for 3.3 Volts and 5 Volts. Continue reading “TB6612FNG Dual DC Motor Driver and Arduino Circuit guide”
In this feature, I am going to do a 360 degree mod on a micro servo motor for continuous rotation. I go through the modding step by step with clear pictures of the conversion process. Also, Python code will be included to drive the servo 360 degrees from the Raspberry Pi. Continue reading “360 Degree Mod for Servo Continuous Rotation – Guide”
