decade counter lab experiment using ic 7490 nsure proper power supply (5V DC) connections. Check for correct wiring of outputs and clock input. Use debouncing circuitry for manual clock pulses to avoid erratic counting. Confirm that the reset and preset pins are correctly connected to control the counter operation.
