555 timer circuit + ? (sort of binary counter circuit ) + 7 segment display circuit = a counter circuit.
Need help can you give me the missing circuit its diagram and components values. Thanks in advance
sir i want to design an addiction avoider by using electronics ,ie, when u are in addiction some high freq was developed in our mind by using synchronization techinique high freq is converted as a normal freq
please help me to design this circuits
i have block diagram that consists of 3 sensors(eeg) fallowed by 4 amplifiers then an microcontroller ATMEL8515 then 2 oscillators then stereos r &h
Thanks dougy83! thats exactly what im looking for. Im planning to make a 4 digit 7-segment counter.I will search on the internet for the rest. Thanks again
The counting will be from 0000 to 11011 (0 to 27 ) so i need 4-7490IC and 4-4511 IC and 4-7-segment LED display.

If you want it to reset after a 27 count, you may wish to use an additional binary counter (e.g. 74hc4040), with the same clock - then connect a few diodes (to detect the 28th count) from the counter to both counters' reset lines.
