How to Use a Breadboard

May 14, 2013

Welcome to the wonderful world of breadboards. Here we will learn what a breadboard is and how to use one to build your very first circuit.
  • Sounds like your wiring is good. You have copper pads soldered to the following pins: 33, 32, 25, 17, 16, 15, 1, 0?

    Try just reading in one pad and building up from there.

    Also make sure your volume knob is functional. Try disabling it and setting the volume to a constant for testing purposes.

  • Hi. There is no wiring diagram currently and no plans to make one. All the wiring is straightforward: each copper tape pad is soldered directly to eight of the TouchSense Pins (You’ll have to solder to a few on the bottom of the Teensy). Take a look at the code to see which pins were used. I used the Teensy graphical datasheets to find which pins I could use for capacitive touch.

    The two buttons and two potentiometers are hooked up in a normal configuration. I actually need to switch the Vcc and GND on mine so the knobs function in a more predictable manner (ie turning to the right turns the volume up, not down). The only big gotcha is the trace that needs cut, which is highlighted above. Feel free to share your creation here or on the GitHub repo. Best of luck.

  • What type of environment was your Weather Shield exposed to? Very humid environments can have adverse effects on humidity sensors. One possible solution is to place a PTFE Filter over the humidity sensor to prevent water particles from entering the sensor and potentially shorting out the internal circuitry.

  • Yes, each module comes with a unique MAC address, found printed on the module’s sticker.

  • Hi. While it is not possible to calibrate the I2C sensors, you can always program an offset into your code. In most cases, the temperature sensor will read a little higher than the actual temp due to the residual heat that the Photon emits through the Weather Shield. Comparing to an existing temp sensor, as you have already done, is a great way to see how much hotter the Photon readings are. Create a simple algorithm in your code to compensate for the extra heat, and you will have more accurate data. 5 degrees C seems like a big error, even with the extra heat. If the temperature is reading that far off, there may be another issue.

  • HI, The RN-52 can only be active as a slave device, not a master, meaning it can only be streamed to, not from.

  • No, two RN-52s cannot talk to one another because they are slave devices only. The RN-42 cannot handle audio transmission. It is for low data rate information only.

  • All of the Photon Shields come with stackable headers soldered on, EXCEPT the weather shield, which has regular, non-stacking female headers, as it’s meant to be on the bottom of a given stack.

  • Hi, those readings don’t sound correct. The sensor should be reading close to zero when completely dry and close to the maximum value of your ADC (ie 1023 for a 10-bit resolution) when submersed in water. Are you powering the sensor with 5V? Why are you multiplying the reading by the decimal value above?

  • If I’m understanding you inquiry correctly, the answer is no. The RN-52 can only act as a slave device, allowing master devices like smart phones or PCs to connect to it. It cannot be a master device that sends data to an Arduino or other Bluetooth enabled devices.
