Abstract or project description

Abstract - In this research paper I am going to describe the process by which I was able to program and use an Arduino UNO microcontroller and a potentiometer to control my powered sled, as a replacement to a transmitter and receiver, which is an essential component to control the motor speed. Since I live in Switzerland, where there is an abundant amount of snow, I decided to construct a sled with a relatively big wooden propeller mounted on the back which would result in the person sitting on the sled to be pushed forward. However, multiple electronic components are required, such as a brushless motor, batteries, an emergency stop button, and a motor driver.  Typically, this last component is implemented using an ESC (electronic speed controller), a transmitter (fig. 1) and a receiver (fig. 2) which allows the person operating the sled to control the speed of the motor by applying more or less power to the transmitter gimbal which sends signals to the receiver connected to the ESC. Given the high cost of the overall price of a transmitter and reviver, which is about $450, I was prompted to look for a cheaper substitute. Hence, I decided to investigate the feasibility of an Arduino microcontroller for this purpose. In fact, the Arduino, combined with a potentiometer, costs about $40, which is distinctly cheaper compared to the original price of $450. This paper will describe the process of implementing the powered sled using an Arduino microcontroller to successfully drive the vehicle’s motor.
