I have a few things to finish and then I am ready for September 2015 to start teaching about the Internet of Things. I will be teaching a Game Development class of 2D and 3D games to teach computer programming, a Robotics class to teach electronics and the Spark Core or Photon web connectivity and …

Been doing some work with IFTTT. see the link at [image] Photon publish to IFTTT to PHP to IFTTT and back to the Photon Integrations This is so cool that I made it into it’s own topic. Say you wanted a PHP file or database to crunch some numbers for your photon and send …

Latest thing working is both Cloud9 and the Particle.io CLI and a simple example of using webhooks [image] Photon publish to IFTTT to PHP to IFTTT and back to the Photon Integrations So I made my own version of the cloud9 for particle at and have also included my own v…

Really enjoying using: Particle.publish("Log-this-to-google-drive", data, 60, PRIVATE); Particle.publish("Log-this-to-google-drive", String(myInt), 60, PRIVATE); Particle.publish("Log-this-to-google-drive", String(myFloat), 60, PRIVATE); anywhere in my code and monitoring it live over wifi …

While my Robotics class is waiting for sensors to arrive, I am looking into Neural Networks using the Photon at [image] Photon with TensorFlow Google's Artificial Intelligence Software General Wondering if anyone is interested in getting TensorFlow working with data from …

Just got my class sets (15 each) of Pololu: DC motors, Stepper Motors and Servos. Hopefully test tomorrow if the following code works. It should allow each pair of students to work all three types of motors using one photon For the code to work students will need to power D6 with a switch from 3V3.…

@rocksetta , you are correct in you statement that the servo and stepper motors should be powered from a separate supply and not through Vin. The Photon has a reverse polarity diode on Vin which is rated for 3A but potential current spikes in the motors can exceed that. The Pololu motor controller …

I am good with the Servo and DC Motor, but my stepper is confusing me a bit. It is fairly small, only 3.9 V and 600 mA. https://www.pololu.com/product/1204 I may have incorrectly assumed my dual motor driver https://www.pololu.com/product/2135 would work with it, but have not found any examples o…

@rocksetta , perhaps the best goof-proof approach, especially with students is to get the Pololu low voltage stepper motor driver: [image] Pololu - DRV8834 Low-Voltage Stepper Motor Driver Carrier This is a breakout board for TI’s DRV8834 microstepping bipolar stepper motor driver. It has…

I agree as the stepper motor driver only takes 2 digital pins to control, instead of the above 4 pins. I will look for one that allows higher amps so that we can control larger stepper motors (Some students want to make robot hands etc), but for the present moment, looks like my DC motor driver hack…

Oops, my Bad. No common ground for the Servo. Somehow it found a ground for the first loop. Might be more complex since that was just on my debugging run.
