🔹 IC: 4017 Decade Counter
BCD Counter PCB Kit UART or I2C)Build a working BCD counter circuit from scratch and discover how digital logic ICs transform a simple count into a visible output. The BCD Counter PCB Kit uses real TTL logic the XD74LS90 decade counter, XD74LS47 BCD to seven segment decoder, and XD74LS42 BCD to decimal decoder to count from 0 to 9 and display each digit on a 7 segment display. All components are easy to solder through hole devices, making this an ideal first step into digital logic
