🔌 Pin Configuration Overview (DIP-16)
Clock (Pin 1): Input pulse for incrementing the counter
Enable (Pin 2): Enables clock input
Reset (Pin 15): Resets counter to 0
Carry Out (Pin 5): Used to cascade multiple counters
Outputs (a–g): Directly connected to 7-segment display
VDD / VSS: Power supply pins (Pins 16 & 8)
📚 Applications
Digital counters (0–9)
7-segment display timers
Event counters
Frequency counters
Scoreboards or step trackers
🔧 Basic Usage with Arduino or Logic Circuit
Connect clock pulses (from Arduino or 555 timer) to Pin 1
Outputs a–g connect to a common cathode 7-segment display
Use RESET (Pin 15) and ENABLE (Pin 2) to control count logic
Carry Out allows chaining to another CD4026 for multi-digit display
