Introduction: Let's Make Bluetooth 4.0 LE Smart Car

About: ElecFreaks is an open design house founded in March 2011. Our goal is to create rapid prototypes and give small-batch manufacture solution for makers and startups. With over 50% staff as engineers and expanded…

This BLE smart car is completed based on our latest design bluetooth 4.0 chiped- BLEDuino, L298 Motor shield, smart car body. The smart car production is simple, as DIY enthusiasts can complete their own smart car only in the form of building blocks, and the operation is also very simple, just controlling it via bluetooth 4.0 remote control, or mobile phone APP. Here we mainly explain the operation of smart car. With the help of the simple communication protocol, the car can achieve human-computer interaction, so DIY enthusiasts can build smart cars of their own on the basis of adding various sensors, camera modules.

Step 1: Hardware Preparation

Step 2: DIY Process

  1. Plug the L298 Motor Shield into the BLEDuino.
  2. Access the smart car motor into the L298.
  3. Fix the 12V lithium battery onto the smart car body via the cable tie.
  4. The assembled remote control and BLE smart car was shown in the picture.
  5. Remote control operating instructions.

Step 3: Summary

When the small car and the remote control access to electricity, the remote control will automatically connect the car. Push the remote control throttle to a certain position, and then push to the direction you need, the smart car would be driven to the direction. If you want the car stop, just pull the throttle to the lowest location. The Demo only briefly illustrates controlling the car by remote control, if the users want to control the car through the APP, the using method is the same.
