Tutorial - Photon Remote Temperature Sensor

Great suggestions, thanks for sharing! :D
Tutorial - Hazardous Gas Monitor
about 3 weeks ago
Hello! Hope you were able to figure this out! If not (and for other folks who may have the same question), the D7 pin is connected to the relay ground that controls the power to the CO (MQ7) sensor. In the schematic, it’s the orange wire going to the MOSFET. Hope that helps!

Good question! Also thanks for following up. Yes, denting of the top platform board was an issue. Didn’t see any denting in the hardwood when standing but it did get a bit dented after the jump test. The addition of metal plates above the load cell buttons is a great idea and would likely help a great deal, otherwise choose a plastic or metal top platform. Hope that helps and happy building!
Tutorial - Getting Started with Load Cells
about 8 months ago
Hello! Thanks for the clarification re: load cell vs. load sensor.
In a somewhat related question to the previous comment, is it possible to connect 4 load cells to the amplifier board? For example, could I connect them in parallel and then calibrate w/ the resulting effective circuit resistance? Any info you could provide about using multiple load cells w/ one amplifier would be greatly appreciated. Thank you!
Update (8/30/16): Figured it out – can connect multiple load cells in parallel!

Both variables are used in the parent source code written for the “Getting Started with the EL Sequencer” tutorial. As they aren’t essential to this particular project, feel free to remove them in your version. Hope that helps!
