Hi All,
I have this problem I have assembled the circuit for 1 second timer which is displayed on the 7 segment display using 4510 and 4511 and the frquency generated from the pulse generator. Now my problem is the 7 segment display displays 4,5,6,7,8 properly but 9,1,2,3 are displayed as 8 but if a stop the pulses after attaining 9 then after few seconds it displays 9 properly, similarly for other numbers 1,2,3. If I observe the 7 segment letters of the troubled letters, the voltages are falling slowly not instantly. Could somebody help on this? I have designed the board on the bread board, the problem is because of this?
Thanks in advance,
Regards,
Satya
