@inq @davee @inst-tech I followed your advice, but it still didn't work. I have not noticed smoke coming out of the board, but I think my previous...

Welcome to the forum!

@zander @inq @frogandtoad Ok, understood. I will modify the robot so that it can work with 2 3.7v Li-Ion batteries or some other source above 7 vo...

@zander Yes, the board operates from 6v onward, but that's only on the Vin pin. I used the 5v pin, which can be supplied with 5 volts. The only ...

@zander If the voltage is 4.8v, I don't see why it should be a problem to bypass the regulator, since 4.8v is close enough to 5v to work anyway. ...

@frogandtoad Four times 1.2v is 4.8v, and my teachers at school told me an Arduino has a 10% tolerance. 90% of 5v is 4.5v, so 4.8v is enough. ...

@frogandtoad That's why I was using the 5v pin instead. I've tried on another board, there is the same issue.

@inq 1) For what I've heard, the 5V pin can be used as either an output or an input. I've used it as an input before and it did work. 2)I've tr...

@inq The gearmotors are similar, but not the same. The GM9 has a much higher torque (almost six times) and slightly lower RPM than the typical ye...

I don't think it is really hardware experience...it is most likely just a lack of patience. But I managed to make most of my projects work in the en...

@inq Good luck with your robot project, I hope it can work in the end! I've also noticed that you do much more testing for this robot than I ...

@hapiel Welcome to the forum, I hope you have fun here and find this forum useful. Your humanoid robot project seems really interesting, it would ...

@jonnyr Nice, I really liked the original DB1 and I think it is a pity that it was never completed. I hope you post updates here on the forum. H...
