You can use that guide to install the offline Arduino IDE that will run from your computer, and to learn how to troubleshoot any potential issues you might have when writing your first programs. You can see how to connect this board to your computer by checking this Getting Started Guide. We will see some of those features in action in this collection of exercises.

The Arduino MKR1010 (read “maker ten ten”) is a microcontroller board featuring a chip that will allow you making either a WiFi or Bluetooth wireless connection to other boards or computers. Installing and using third party applications.This exercise requires having previous knowledge in: Understanding how the CSV file format works.Read data points and store them into files inside a computer.Graphing data in real time with the Arduino editor.The second technique will use an external program to store the data into a CSV (comma-separated values) file that you will be able to import into a spreadsheet program like Libreoffice Calc, Microsoft Excel, or Google Sheets.

The first technique will involve the use of the classic Arduino editor, which includes a simple tool to draw graphs out of data as it arrives over the serial port. While developing this project, you will be introduced to two different techniques for graphic real-life data coming from your board. Graphing data is a very powerful way to reaching a better understanding of what is going on with the data. While sending data to the terminal is a good way of seeing what is happening on the board, there are other ways to see data that will help making sense of the information. The video above shows a wireless potentiometer connected to a wireless LED.IoT-Prime Experiment 2: Ways of graphing your data Introduction

Just be sure that the the transmitter's address is set as the receiver's I/O input address setting (ATIA). Now that you know how to connect an LED to the PWM output of an XBee radio, take a look at our input tutorials for what can change the brightness of the LED.

Your circuit should look something like the diagram above.

Insert the XBee into the breakout board.

Connect the LED's cathode side (the shorter lead) to the ground bus and the anode side (the longer lead) to the PWM0 pin, which is the 6th pin down on the left side.

Connect the VCC terminal of the XBee adapter to the positive rail and the ground terminal to the negative rail.

Place the XBee adapter into the breadboard.

If you don't issue this command, the radio will revert to its old settings when it loses power. Note: Remember to issue the ATWR command when you're done so that the settings are saved in the radio's flash memory. Here’s what your terminal session might look like. N/A (resets the radio to its factory settings)ģ001 (any address from 0 to FFFE will do)

Here are the commands we're going to use to configure the radio:.

Launch CoolTerm and connect to the XBee.

Insert the XBee into the Explorer USB and connect it to your computer.

If you're not familiar with configuring radios using AT commands, review the steps in the Basic XBee 802.15.4 Chat tutorial, which walks you through configuring CoolTerm to program the radios.

A DC power source, 2.8 - 3.3V - We'll be using two C batteries in a battery holder from Radio Shack.

XBee Explorer USB - for programming your radio.

XBee Breakout Board - for your circuit.

To hook up a LED to an XBee for PWM output, you'll need: When we do that, we can control the brightness of the LED wirelessly. XBee radios have two PWM outputs and in this tutorial, we're going to connect an LED to one of them. This happens very fast-about 16,000 times per second. If you want something half-way between off and on, 1.65 volts, the DAC will keep the pin high for 50% of the time and low for the remaining 50%. That is to say, the PWM output pin will always be high.

A full 3.3 volts from the XBee will have a 100% duty cycle. They do this by switching the pin between high and low with different duty cycles. PWM stands for pulse-width modulation and it's a way for digital devices to do their best at acting like they're outputting an analog signal using a digital to analog converter (DAC). When it comes to outputting analog, the XBee has another trick up its sleeve and it's called PWM. In our potentiometer tutorial, we used the XBee's built-in analog-to-digital converter (ADC) to convert the analog voltage values from a pot to digital information that the XBee can transmit. Many times in the world of digital, a device will have to interface with analog components.
