====== Robots tapeurs ======
Je reprends les petits robots [[https://bricoles.du-libre.org/esp8266:tapoteur|tapoteurs]] pour actionner un solénoïde frappant des cordes sur l'installation.

Ils sont commandés par un patch puredata de Dom en fonction de l'environnement sonore.

=== Le dernier code ===

<code c>
/* Wemos_tapeur
  gepeto@du-libre.org 2018
  objet frappant , commande par Wifi / OSC
  la commande OSC est programmable
  // a cause de OSC sur purdata on garde que des float !
  sorties :  1, 2, 4, 5, 6, 7 //ok pour 1,2,4,5,6,7
  /tap   \(float\) \(float\) ms \(float\) duree \(float\) pwm-force"));
  /tap   ffff 6 200 2000 1000
  /tap 6  vide arrete 6
  /stop arrete tout
  /modforce 2 500 modif force de frappe du 2 en 500

  Pour entrer dans le setup il faut allumer l'ESP en touchant A0
  la led clignote rapidement
  on se connecte sur le SSID SNHACKTAP 192.168.4.1
  apres validation la led clignote doucement

  Matériel: ESP Wemos + driver wemos moteur + platine wemos alimentation
