NodeMCU WiFi Car

 WiFi Car

  In this Tutorial I will Show you How to Make a WiFi Car Using NodeMCU ESP8266 Board and Some Electronic Components . You can Watch this Video or Read the following blog for more details..

Components Required :

• NodeMCU Board
• L295N Motor Driver
• Gear Motors and Rubber Wheels
• Jumper Wires
• Li-ion Battery
• Glue Gun

Construction :

• First you need a cardboard of high Durability.
• And Mount a Gear motors Using Double Sided Tape or GlueGun.
• Place the NodeMCU ESP8266 Board on the Cardboard and Connect it to L293N Motor Driver.
• Connect the Gear motor Wires to the L293N Motor Driver.
• Now move on to the Software Portion, Open Your Arduino IDE
• Open Fauceter_WiFi_Car.ino file 
• Select Board & Port , Click Upload .
• Now time to Connect a Battery. I use 2no's of li-ion 3.7V battery in Series Connection.
• After Connecting Batteries, Switch on your Car and Place it on Track.
• And Install Fauceter WiFi Car Application on your Smartphone to Control the Car.
• That's Solve Guys !

Circuit Diagram :

        You can follow our DIY Video for Circuit Diagram. I will clearly explained the connections of this WiFi Car. Connect IN1 > D0 , IN2 > D1 , IN3 > D2 , IN4 > D3 and ENA & ENB > D5 & D6
