Smartphone Control of RC Cars

The smartphone-controlled RC (remote-controlled) car is an inexpensive remote-controlled car designed to be fast and portable. Instead of manufacturing, packaging, and shipping a separate controller, the remote control is implemented in a phone application, which saves time and money in both the design process and the manufacturing process. Utilizing the user’s smartphone is more cost-effective since mobile devices are a common recurrence, and packaging fewer devices results in overall better portability of the product. This smartphone-controlled car is speedy and intuitive to learn for typical smartphone users. The user can change the car’s speed and direction wirelessly using their phone; the speed and direction also change in real-time. The wireless connection between the smartphone and the car is maintained for a reasonable distance with little to no delay in RC car movement. The RC car is small enough to be comfortably carried in a backpack or in one hand, but is still large enough to fit the internal hardware. The car has software embedded into the hardware to wirelessly communicate with the user. Based on the input data transmitted from the smartphone, the embedded software also sends signals on the hardware to change wheel speeds and directions
