This paper is aimed to control the speed of peanut planting system. The system introduces a control mechanism to drop the seeds at a particular position with specified distance, to achieve desired seed rate within the row, uniform seed spacing and alarm system. The overall system includes motion sensor, proximity induction sensor, two servo motors, three DC motors and alarm system. These parts are controlled by Arduino Mega 2560 which is the heart of the system. The battery 12V, 5AH Lead Acid Battery is used for the whole system. So, the wheel motors of machine are controlled by PWM DC motor speed controller separately. Another DC motor is used to stir the seeds within the seed storage tank. When there is no seed to detect within the seed storage tank, it sends the signal to the Arduino and indicates the alarm. To get equal seed spacing or seed to seed distance, proximity induction sensor is used. Servo motors are used for precise control of seed rating. The paper presents calculation of gear ratio, desired motor RPM, PWM out level are also described completely.
