Description In this demo we show how to create a zumo robot basic controller. For this we will use the FRDM-KW41 card, an H bridge, and a cell phone with the NXP IoT toolbox application. From the application we will send the characters F forward, S to stop, B to back, L to left, R to right. The FRDM-KW41Z highly-sensitive, optimized 2.4 GHz radio features a PCB F-antenna which can be bypassed to test via SMA connection, multiple power supply options, push/capacitive touch buttons, switches, LEDs and integrated sensors. Video Diagram and Schematic Step by Step guide First, we need to have MCUXpresso installed and open. Download and load the Zumo Robot project in MCUXpresso. Install NXP IoT Toolbox app. Compile the project, connect the board and load it. Connect the card as indicated in the schematic Connect the power supply. Press switch 4 on the board. Open NXP IoT Toolbox, select Wireles UART and connect with the board. Now you can send the characters mentioned in the description.
