# Esp8266-Laser
Wifi Host for the Arduino-Laser-Spirograph

HTTP endpoints:  
  /spirograph   GET returns laser and motor values (0 at startup)  
                POST sets new value(s)  
                    laser=1-128 (1:permanent, 2-127 pulse, 128 off)  
                    motor1=1-128  
                    motor2=1-128  
                    motor3=1-128  
                    
                
  /wificonfig ->    GET returns wifi settings  
                    POST sets new wifi setting{s}  
                        apMode=0: will try to connect to SSID first, 1: will directly start the AP  
                        SSID=ssid  
                        password=password  
                        save=true will save config to spiffs, false will only change RAM variable (useful for onetime ap joins)  
                        apply=true will reset wifi and try to connect with new param (buggy atm)  
  /saveconf ->  POST write wificonfig to file (similar to wificonfig->save=true) 
  /resetwifi -> POST reconnect wifi (similar to wificonfig->apply=true) 
  /heap ->  GET returns free heap of the ESP8266  
  /files -> GET returns list of files
