@inq Thanks for the encouragement. Unfortunately PWM control does not work on the L298N unless you use a voltage higher than 5v (I don't know e...

@inq Since you wanted to see pictures, here they are. Today I've finally made the motors work. However PWM did not work, so I will have to f...

@inq 1)I will probably take some pictures when I make further progress. The robot is still unfinished. 2)The HC-SR05 has a slightly longer rang...

@mark-bolton @inq Yesterday I've started assembling a second version. It will use an arduino nano instead of an uno so that the connections are ...

@inq I tested the SG90 with a servo tester during the four-legged robot project, and they could not move further than 120 degrees. I think a se...

Ok,

@robotbuilder The other link you sent me is correct (the one on the DFrobot wiki). Do you know what could cause the address issue?

I'm using the I2C scanner from the Wire library. The display is a DFRobot Gravity Display /p> I've used the code from the library made by DFRobot ...

@boggiano Your robot car seems interesting. I have recently finished my own 2 wheel car with bluetooth control. It was supposed to have a rotati...

@boggiano Welcome to the forum! Since you're into robotics, did you build any robots? If so what do they do? I'm curious to know. Have a nic...

@inq Yes, you're right, it will probably help even though the robot already turns quite quickly on the spot. I've actually fixed the servo issue, ...

@inq Update: I've managed to make the motors work, without too many issues. I've also managed to make bluetooth control work as well. Th...

@zander @davee @inst-tech @inq @frogandtoad I've just discovered that the issue was completely different. I had soldered the barrel jack that conn...

@zander @davee @frogandtoad Thank you for your advice. Since there is no continuity between the input and GND of the voltage regulator (and thus n...
