[distance 2D][0.4m - 20m][air/water][technology choice?]

hi guys, i building robot m stuck when calculating distance between arduino , beacon attach on something, distance between beacon , arduino can goes 0.4 meters 20 meters let s 0.40 meters error accceptable accuracy need. my issue not capable find orientation part of robot due fact can underwater or not: ble seems not accurate due field of application. knowing aldready use 433mhz network send other data arduino elsewhere on ground. do guys have clue of technology should use solve problem? you need different technologies air versus water. for air, laser distance sensors lidar-lite work -- 40 meters or more range +/- 2.5 cm accuracy. for water, sonar works well.

central meteorologica no sensa bien

hola gente vengo aqui para ver si me pueden ayudar, tengo una estacion meteorologica conectada internet con una ethernet shield conectada la linea electrica, cuando probe el arduino y el ethernet la pc censaba correcto y cada frecuencia programada... pero ahora que esta instalada y conectada la linea de 220v me tira resultados erroneos y ademas como que se cuelga y manda siempre los mismos datos hasta que la tengo que desenchufar y volver enchufar, el circuito lo alimento con una fuente de un cargador de celular. se agradece cualquier idea porque no tengo idea por donde arrancar con que fuente alimentas arduino y el shield ethernet, tensión y corriente por favor?

bonjour à tous et à toutes, je suis en train de faire un petit jeu (snake) et je voudrais simplement redémarrer ma carte arduino afin de remettre toutes mes valeurs à 0 (comme lorsqu'on appuie sur le bouton physique de la carte). j'ai vu sur internet que certains utiliser une bibliothèque 'watchdog' mais j'ai vu sur ma carte arduino une broche "reset" (voir photo). comment fonctionne-t-elle ?  faut-il simplement envoyer du courant depuis une sortie classique avec un digitalwrite ? avant de faire des test qui pourrais détruire ma carte je vous demande votre avis... merci d'avance pour vos réponses.  bonjour, la méthode est décrite ici mais tu peux simplement faire un saut à l'adresse 0 comme décrit aussi dans le lien ci dessus ou simplement faire un jmp assembleur à l'adresse 0 code: [select]   asm volatile ("jmp 0"); Arduino Forum >...
