SparkFun gator:bit v2 Hookup Guide

January 31, 2019

The gator:bit v2 is a breakout board for the BBC micro:bit. The gator:bit exposes almost every pin on the micro:bit to clippable pad with circuit protection. It also has as built-in addressable LEDs and a built-in buzzer.

Single Supply Logic Level Converter Hookup Guide

August 9, 2018

The Single Supply Logic Converter allows you to bi-directionally translate signals from a 5V or 3.3V microcontroller without the need for a second power supply! The board provides an output for both 5V and 3.3V to power your sensors. It is equipped with a PTH resistor footprint for the option to adjust the voltage regulator on the low side of the TXB0104 for 2.5V or 1.8V devices.

Electret Mic Breakout Board Hookup Guide

June 23, 2016

An introduction to working with the Electret Mic Breakout Board.
  • That will work as well.

  • For Arduino programming you'll need a 3.3V FTDI breakout board just like you would to program a pro mini. If you'd like to update the firmware on the VSLI chip you'll need the VSIDE IDE and use the UART pins on the right side of the board to program it.

  • The Papa Soundie can only play 1 audio file at a time. If you are looking to play or mix multiple files (up to 14 stereo tracks) I'd recommend the SparkFun WAV Trigger.

  • You can take a reading as often as you'd like from all or specific sensors on board and set up the alarms how they make sense to you. It's part of what we were going for.

    We were optimizing energy - With three sensors on board and powering the microcontroller every energy savings we could take we did. If we had seen mA anywhere in our measurements we would have considered our experiment a failure by our own standards.

  • Not hard at all. We just intermittently power the device for a second or so 24 times a day. This also drastically reduces corrosion. Maybe something to consider for the next round.

  • I don't see a need to take measurements more than once an hour. The most interesting times to take more measurements are at sunrise and sunset. Every reading can change enough to make the graphs less boring.

    The alarms are set in Cayenne. It's easier set up a text alert from the My Device's platform than try to build it into the app. Though it could be easy enough to do it with a python script if you are using a Raspberry Pi to read the data. I haven't used an Alexa or Echo - I bet you could ask Alexa to sound an alarm under some conditions.

    I also noticed a typo in the blog post - when taking powering the sensor and reading the data the current is 152uA not 152mA.

  • I've never needed a claw hammer for my home office more than I do now. Might even need 2.

  • I think you can manipulate it in code but you won't be able to change the pitch while playing. You'd have to tweak it, play it, tweak it, play it, etc. The VS1000D firmware is in the repo, have at it.

  • This isn’t a headphones application. You can plug headphones in, get a tiny amount of sound but the product needs to be used with powered speakers.
