![]() ![]() To read/save/modify any file without user interaction: Set up the arduino to act. To print information to the Arduino IDE Serial Monitor. If connected to a computer, the data can be saved by reading the serial. Serial object on standard Arduino boards. Once you flash your own firmware to your device it will no longer have Tinker functionality.Teensyduino provides a Serial object which is compatible with the Or from the Particle CLI: particle flash my-device-name tinker Android Users: With your desired device selected, tap the options button in the upper right and tap the "Reflash Tinker" option in the drop down menu.Then tap the arrow next to your desired device and tap the "Re-flash Tinker" button in the pop out menu. iOS Users: Tap the list button at the top left.To reflash Tinker from within the Particle mobile app: If your device is new, it already has the Tinker firmware on it. It's just that with the Tinker firmware, we've specified special Particle.functions that the mobile app knows and understands. It's just like the user firmware you've been loading onto your device in these examples. Your device already knew how to communicate with the mobile app because of the firmware loaded onto your device as a default. CoolTerm is an easy-to-use terminal for communication with hardware connected to serial ports. Your device is always listening to the cloud and waiting for instructions- like "write D7 HIGH" or "read the voltage at A0". It keeps the same spirit while not containing a LED driver using some more. When you tap a pin on the mobile app, it sends a message up to the cloud. The screen accurate font of the lightsaber sounds from the games Dark Forces. Remember back when we were blinking lights and reading sensors with Tinker on the mobile app? The setup for your breadboard is the same as in the last example. When you remove your finger, the event says that the beam is now intact. As you put your finger in front of the beam, you'll see an event appear that says the beam was broken. ![]() You can check out the results on your console at. If you mess up, don't worry- you can just hit "reset" on your device and do it again! Put your finger in the beam when the D7 LED goes on, and hold it in the beam until you see two flashes from the D7 LED. Basically, a tripwire!įor your convenience, we've set up a little calibrate function so that your device will work no matter how bright your LED is, or how bright the ambient light may be. Every time the beam is broken or reconnected, your device will send a Particle.publish to the cloud letting it know the state of the beam. In this example, we've created a system where you turn your LED and photo sensor to face each other, making a beam of light that can be broken by the motion of your finger. We're allowed to name that event, set the privacy of that event, and add a little bit of info to go along with the event. Particle.publish sends a message to the cloud saying that some event has occurred. What if we simply want to know that something has happened, without all the information of a variable or all the action of a function? We might have a security system that tells us, "motion was detected!" or a smart washing machine that tells us "your laundry is done!" In that case, we might want to use Particle.publish. Make a motion detector: publish and the console Intro Now you can turn your LED on and off and see the values at A0 change based on the phototransistor or photoresistor! ![]() Particle variable get device_name analogvalueĪnd make sure you replace device_name with either your device ID or the casual nickname you made for your device when you set it up. You can also check out this value by using the command line. (Be sure to replace your-device-ID-goes-here with your actual device ID and your-access-token-goes-here with your actual access token!) ![]() You can see a JSON output of your Particle.variable() call by going to: Pin an an OUTPUT instead of digital input. The setup() function is called once when the device boots to, well, set up the device. If you leave this out, your code won't run (and the LED will not blink) until you've connected to the network and the ParticleĬloud successfully (breathing cyan). If switch a is closed, current will flow through the a segment of the LED to the current limiting resistor connected to pin a and to 0 volts, making the circuit. You mostly just need to know if you add this line, your code will run immediately at startup, before connecting to the cloud. In this example, the segments of a common anode display are illuminated using the switches. You can learn more about threading in the firmware API reference, but for now You could change the constant in this one place at the top of the file. If you wanted to use an external LED connected to D2, for example, This defines which pin we want to blink, in this case D7. This code has a lot of comments, but a few things to note: ![]()
