A newspaper vending machine is an automatic machine for selling newspapers and customers operate it by themselves. The advantages of vending machine method are meet the concept selling anywhere, closer to customer and cost down in sales. This vending machine uses some coins or money to initiate selling process. The aim of this research is to applied microcontroller to control newspaper vending machine, Programmable Logic Device (PLD) to count coins, light sensor to detect the coin, sensor TCS3200 is used to detect color of money, dc motor to eject newspaper from vending machine and LCD show instruction to purchase the newspaper. The type of microcontroller in this vending machine is ARDUINO ATMEGA328, PLD IC is GAL 22V10. The coin using Rp 1000 and money using Rp 5.000. The newspaper inside the machine is daily newspaper area with the price is Rp 5.000. It means the buyer can buy the newspaper using 5 pieces of coin Rp 1000 or money Rp 5.000. Photodiode and infrared sensors can be used to detect coin. Motor to eject newspaper activated if the amount of coin inserted the machine is 5 coin of Rp 1000. Technology Programmable Logic Device (PLD) can apply as decoder binary to decimal with seven segment displays to count coin for 5 coins. The value of RGB for money Rp 5.000 is read from 4 sides. RGB value of color for the image “tokoh” has range 20<R>14, 20<G>20, 20<B>16. RGB value of color for the image “garuda” has range 10<R>8, 8<G>10, 7<B>12. RGB value of color for the image “tenun” has range 11<R>14, 10<G>14, 14<B>10. RGB value of color for the image “Rp 5000” has range 10<R>8, 11<G>8, 8<B>7. DC motor to push will active if RGB value Rp 5000 is detected and suitable with RGB designed. The guide of using newspaper vending machine to customer is shown to customers trough LCD and will show "VENDING MACHINE 1 KORAN 5000 ATAU 5 BUAH KOIN 1000".
