Esp8266 Node Mcu Control Motor Servo Relay Switch Wifi internet Udp <br /> <br />In this video. .I used Esp8266 Nodemcu Devkit 1.0 with esp8266 12E module,Crius SBEC power supply,Mg995 Servo and 3 Leds. <br /> <br />On the Android Tablet WiFi Hotspot/AP is turned ON. <br />The Esp8266 and the second android phone are both connected to that hotspot( in a local Network). <br /> <br />Using the RoboRemo free app i can send commands to the ESP8266 to turn on/off the GPIO Pins and in this case send a PWM Signal to control a Servo motor and three Leds and everytime the Esp8266 receives a command from the phone it sends back a reply message which can turn ON the "led" in the RoboRemo app U.i. <br /> <br />The command from the RoboRemo app is sent as a "character array/ string " via UDP and it works over the internet also where esp8266 is connected to one WiFi with internet access and the Android phone with RoboRemo app is connected to a second Wifi or has Internet access over 3g/4G etc . <br /> <br /> <br />Please visit my Blog : <br /> <br />https://AmkDiyprojects.Blogspot.com <br /> <br />Sketch/Code Link : <br />https://amkdiyprojects.blogspot.com/2016/10/control-motor-led-relay-lm298-servo-pwm-sensor-esp8266-wifi-nodemcu-udp.html <br /> <br /> <br />If you need help or if there is any problem comment on the video or on the blog I’ll try to reply asap and please Like and Subscribe
