can you put the codes of your obstacle avoidance robot please

[farahmaad]

😭😭😭Please I need the code very badly please give me the code

[bossfun]

please send me the code, greetings from germany

[imanebezzaz]

hey! i wanna ask you cause i connected my arduino uno and this code didn't work

[MuhammadSalman-mf]

bro can you share the code for controlling the motors

[sergerobichaud]

Hy can you send me the diagram and sketch please cause your link not working

[JabiloJoseJ]

Cool bro....that ultrasonic sensor holder idea is smart🔥🔥

[kmhooibg]

oh my god no need coding? just install wire only??

[ghislainekegnon]

hello! first of all congradulations for this work, it's so good!!
please i want the code of obstacles avoiding car

[creative_lighting_ksg]

Mera arduino project pura nahin Ho Pa raha hai yaar
Thodi bahut programming mein dikkat a rahi hai

[iyadhmeid]

Bonjour, combien de temp j'ai cherché cette vidéo et maintenant je la trouver
<<Qui cherche trouve>>

[kiranrudra]

This is really helpful vedio & I wan to try. I could find only instructions pdf but not Arduino Sketch. Could you please help me with sketch link please ?.
