An electronic feed device system has an accelerometer (ADXL345), Arduino Uno microcontroller, pull-type solenoid, and a 12-V battery.The system used to design and create a new method to measure and adjust the distance between seeds into hills. The seed metering devices connected with the seeding unit was calibrated laboratory and experimentally studied at the "Test and Research Station of Tractors and Farm Machinery, Alexandria Governorate" to evaluate an electronic feeding device performance for seeding paddy and sorghum seeds. The experiment variables included four operating speeds of 0.5, 0.8, 1.2 and 1.5 k.m.h-1 with a distance between hills of 10, 15 and 20 cm, respectively.The results showed that the maximum qualities of feed index for sorghum seeds were 98.09, 96.96, and 96.11% at operating speed of 0.5 k.m.h-1 at distances between hills of 10, 15 and 20 cm, respectively. The maximum values of seeds longitudinal deviation (C.V.) for sorghum seeds were 9.25, 14.51, and 15.7% at operating speed 1.5 k.m.h-1 at distances between hills of 10, 15 and 20 cm, respectively. An electronic feed device showed a high accuracy for adjusting the distance between hills with no high effect of seeds germination.
