Objective/Technical Details

Created an electric skateboard that uses weight to control the amount of speed at which the skateboard would travel as well as de-accelerate without having to modify a person's stance. This project utilizes load sensors in conjunction with a brushless motor, depending on the allocated weight applied on the load sensor would determine the amount of speed that the skateboard would travel. The applications of the skateboard would be made possible using an Arduino Uno which was programmed to carry out specific functions related to the load sensors

Results/Outcomes

An electric skateboard that can adjust speed by using a weight sensor. The Arduino would send the single to the microcontroller and adjust the duty cycle to change the speed of the skateboard. Two load cells were used to build up a Wheatstone bridge to get reading data from the weight sensors. Arduino program was separated into four different states and each had their task, including waiting for the load, speeding up, adjusting speed, and slowing down. With these designs, a perfect electric weight sensing skateboard was created

However, there are still some problems that can be improved in this project. First, a full-bridge configuration can be used for the weight sensor which can support a better and more stable reading data. Second, more powerful components can be used in the project. For example, a stronger motor and power which can carry heavier weight on the skateboard. Third, a digital monitor for the speed and weight can be mounted on the front of the skateboard which can give more information to the user and help them to control the speed
