💬 FAQ

After connecting everything and turning on the ElectroLab, I don’t see any LED on.

If the board is correctly powered and you cannot see the power LED on, disconnect the power immediately: there is a short-circuit in your board, meaning that there is a wire (with very little resistance) connecting the Vcc 5V and the GND.

After assembling everything and powering the board, the circuit doesn’t do what I expected, why?

The more complex the assembled circuit is, the easier to make a mistake. If the circuit has been tested before, the most likely answer is that there is some error at a certain connection. The solution is to check node by node that everything is correctly connected.

I accidentally inverted the polarity of a component that was marked as polarized, what can I do?

If the component seems damaged from outside or the circuit doesn’t work after fixing it, it is clear that you will need to replace it or send it for repair (check support:).

I want to expand the set of sensors to play with other, can I do it?

Of course! Just make sure are components rated for 5V. Remember to connect both GND together and in case the sensor needs a power supply connect it to the 5V bus-bar.

Can I connect multiple ElectroLab together for making more complex circuits?

Yes, some of the circuits can become so complex that you might need to do it like this. In this case just connect the 5V of one ElectroLab to the 5v of the other and the GND of one to the GND of the other, so both are powered correctly.
