Yes you can. If you do use a battery make sure you also connect the battery ground (-ve) to a Pi ground. However, why not just connect more wires to one or more of the Pi's 5V pins? my 2 pins are already taken for a L298N, so i'm afraid that it's too much for my rpi, do you think that it will be ok...

Salut tout le monde, j'ai besoin d'utiliser 4 capteurs ultrasons pour mon projet mais j'ai plus de place sur les 2 pins 5V de mon rpi, comment je peux faire pour les alimenter ? Il est possible d'utiliser une batterie externe de 5V ?

Merci à vous

Hi guys, i need to use many ultrasonic sensors (4) and my 2 5V pins on my rpi are already taken
can i use an external battery (5V) to power the sensors ?
Ty for ur help
Best regards

like too hot to touch? post your schematic on how you connected everything up if you draw too much umph from the GPIO or put more than 3V on then they you will kill it bad No, not too hot, just a little It was to build a robot (which working until now) but maybe after a long moment the rpi was over...

What model PI, both working and non working? What model PSU? The both are rpi 3b and the psu (for power supply ?) isn't official but it's 2.1A and 5V. does the SOC get hot on the bad one, Yea i think it's a little hot. I bring another precision, it was to build a robot (which working until now) but...

Hi everybody, i was making a robot, all the things worked, but one day, i have turned on the raspberry and no led was on (green and red), so i've decided to take off all the things on the gpios and i have tried again ... Always no led .... I thought that my raspberry was dead. But i've tried a last...

Salut à toi, j'ai quasiment le même projet que toi, on peut peut-être s'entraider ! Mon projet: Faire un robot à 4roues motrices pilotables avec une manette et utiliser un casque vr en carton avec le smartphone dedans, pour controler les servomoteurs qui font bouger la camera, comme cette vidéo : ht...

Ty for the answers guys !
So i've to buy 2 gear motors ^^
these are ok

(i hate the yellow motors xddd )

teazy

You don't give us a great deal of information, but my guess is that the motors don't develop enough torque to get the car moving. A particular issue may be the large diameter of your driving wheels, since this will give the motors a further mechanical disadvantage (like using a lever backwards, wit...

Hi guys, i have to make a robot for my informatic project, all the things are working (the motors run and the servo-motor too). I've printed the wheels with a 3d printer, and i used an inner tube for the tires. I've made a python scrit. When i run it and i lift the robot, the wheels turn normaly, bu...

i want to precise that it worked before with the same charger and same sd card ! That's the problem ! i don't understand. Well SD cards do wear out over time and can fail suddenly, power supplies can also suffer failures especially if they have been worked hard and over heated. You could also have ...

i want to precise that it worked before with the same charger and same sd card ! That's the problem ! i don't understand, What version of what os do u advice me ?

for the sd card, i used that : https://fr.gearbest.com/memory-cards/pp ... id=1433363

teazy

yes but before that, it worked well !
my charger is 5v and 2A, it's enough no ?

Hi everybody, i'm not an english native speaker, but to get more answers for my questions, i ask here ! :p So, i've 2 rpi 3 and i've used them for a long time now, but overnight, i've get some errors :/ i try different os like raspbian or ubuntu mate but it's the same, At the starting, i can access ...

Merci de vos réponses

teazy

D'ac je vais y jeter un coup d'oeil, merci infiniment

teazy

Yep c'est ça ! Ça doit bien s'acheter quelque part non ? (En fait je sais pas trop comment m'exprimer mais disons que le servomoteur faut bien qu'ils permettent de faire tourner les roues, pour ça, il faut une sorte d'axe pour reunir les 2 roues (comme sur la photo ci jointe) et je me demandais où o...

teazy

Salut à tous, Je voulais me faire un petit robot avec un raspberry mais sans le système des 2 moteurs pour tourner (faire tourner un des moteurs plus vite que l'autre pour tourner) et donc avec un servomoteur J'aimerai donc bien acheté les pièces nécessaires comme montré sur l'image ci jointe mais j...

Déjà fait, rien n'y fait :/

Salut à tous, j'ai installé 2/3 trucs sur mon raspberry et je me retrouve sans wlan0 maintenant :cry: mais la connexion filaire (eth0) fonctionne toujours, je pense que c'est dû au fait que j'ai fait : apt-get remove openssl ^^ Voici le résultat d'un ifconfig: http://img11.hostingpics.net/pics/54101...

teazy

Du coup le mieux ça reste 2 moteurs sans servomoteur en faisant varier la vitesse des roues (je sais pas comment dire mais je me comprends ahah) pour tourner ? ^^

Ah et j'oubliais, Joyeux Noël

teazy

Ah d'accord j'ai cru que tu me disais que c'était ma question qui était conne ducoup j'avais préféré ne pas répondre autant pour moi dsl ! https://www.youtube.com/watch?v=H6TOJIxF964&t=36s En fait je voulais m'inspirer de cette vidéo youtube (mais sans le nunchuk wii, je voulais développer une appli...

teazy

Merci tu m'as été d'une grande aide !
Merci d'avoir pris la patience de me répondre (surtout un 24 Décembre !!)
