Introduction: WiFi Phone Controlled Mini RC Spy Car
In this Instructable I'm going to show you that how can you build quickly a simple phone controlled RC car that can record videos. The device is based on the Mediatek LinkIt ONE board and I used an Adafruit motor shield and the Blynk app to control my car. It's a great project for beginners, but even can be fun for others.
Some Informations about this RC Car:
- The main circuit communicates with the phone via WiFi.
- The max control range depends on your router, but in anopened area it's at least 20 meters.
- My camera's resolution is 720p but you can use different
Now let's see what you need.
Step 1: Parts and Tools
For this project you'll need a soldering iron and a glue gun.
- Mediatek LinkIt ONE Developer Board
- Adafruit Motor Shield
- 2 DC Motors
- 3 Bottle Cups
- Wifi Antenna
- A Small Camera
- A plastic sheet
Step 2: The Motors
Solder two wires to each motor and make a small hole on the two cups, that will be used as wheels. It's not the best solution, but works well.
Step 3: Glue the Parts Together!
Heat up your hot glue gun and glue the motors on place. After this add a third wheel, like me, I glue another cup at the end.
Step 4: The Circuit
Connect the shield and the WiFi antenna to the LinkIt ONE and power up with the battery. Charge up the battery and write the software. Don't worry if you can't write this codes, download mine in the next step.
Step 5: How to Install a Library?
- Download the linked libraries from the "Parts and Tools" step.
- Open your IDE.
- Open Sketck/Include Library/Add .ZIP
- Choose your .zip library from your computer.
- And you're done.
Step 6: The Software
Download this code, and upload to you LinkIt One board.
Step 7: The Robot
I used some rubberbands and fixed the circuit on the plastic piece. I did the same thing with my camera. Connect the motors to the M1 and M2 outlets.
Step 8: Blynk Dashboard
Download the Blynk app on your Android/iOS device and build a dashboard like on the pictures. Two joysticks are needed for this project, one controls the left motor, and the other the right.
Step 9: Have Fun!
And you're done. I'll make a video in the next few days, but now here in Europe is night, and I can't make a good quality video until tomorrow. Hope you liked and thanks for watching!
