“…The study focused on processing vehicle images to transmit counting signals [4]. The other research related to object calculation by utilizing image processing are carried out, such as parking area calculations [5], vehicle detection and vehicle number calculation with Feature-Based Classifier [6], vehicle detection for Unmanned Aerial Vehicle Images [7], and counters of motorbikes coming out of the parking lot [8]. Several other research that used 7-segment as displays are conventional 7-segment displays using diodes and transistors arranged in matrix [9], 7-segment display standards for Burmese numerals [10], introduction of 7 characters -segment [11,12,13], 7-segment character modification for Bangla [14], message writing with 7-segment [15], 7-segment control with PIC16F84 microcontroller [16], 7-segment control with AND logic gate, NAND, OR, NOT [17], 7-segment BCD Efficiency with MGDI (Modified Gate Diffusion Input Technique) [18], making six-digit clock with four-digit 7-segment module [19], and four 7-segment units to form a large 7-segment with a single decoder [20].…”

In daily life, we have encountered many 7segments uses. The 7-segment has been commonly used to display public information or the number of calculations (counters). A Control Decoder as a 7-segment driver, IC CMOS and TTL as the decoder controller, has also been widely marketed. Various methods are used to counter the final goal to find out the number of objects. In this research, the researchers performed a 4-digit count-up by using the CD4510B CMOS IC as a BCD Count-Up and CD4511B as a 5-inch BCD to 7-segment decoder SM415001L. The uses of CD4510B ICs as a BCD Up/Down counter can generate binary numbers, according to the results of the counter on pins Q1, Q2, Q3, and Q4. The IC CMOS CD4511B, which, according to the datasheet was intended for 7-segment common cathode, could also be used for 7-segment common anode drivers by adding logic inverting circuits using transistors BC547 and CD4511B CMOS IC, combined with a logic inverting circuit. The 7-segment 5Inch SM415001L could display Count-Up numbers from 0000 to 9999.
