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.

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.
