5x7 DISPLAY
You must be able to recognise components such as capacitors, diodes, zeners, transistors and resistors to build a 5x7 Display project. This information is covered in our BASIC ELECTRONICS course and a complete set of circuit symbols can be found...
Digital visitor counter Schematic Diagram
The digital visitor counter is a reliable circuit designed to accurately count the number of persons or visitors in a room. When an individual enters the room, the counter increments by one, and when someone leaves, the counter decrements by...
Digital Up / Down Counter
This Circuit uses a CD40110BE, Up/Down Counter IC's. This IC is able to Source Each Segment with 25 mA, Giving a Very Nice Bright Display. The 7 Segment Displays MUST be a Common Cathode Type, as I have used here....
Odd-number-counter-divider
This circuit, illustrated symmetrically, divides an input by virtually any odd number. The circuit counts n + 1/2 clocks twice to achieve the desired divisor. By selecting the appropriate n, which is the decoded output of the LS161 counter, divisors...

Johnson digital counter circuit diagram using D flip flop 7474 (3 bit/4 bit) with animation/ simulation
The Johnson digital counter, also known as the Twisted Ring Counter, is a synchronous shift register that incorporates feedback from the inverted output (Q`) of the last flip-flop. The Q` output of the final flip-flop is connected back to the...
digital counter circuits
The circuit in Figure 1 is a 4-bit asynchronous counter, also known as a ripple counter. It consists of four J-K flip-flops with their J and K inputs connected to logic 1. This configuration causes the output of each J-K...
Coin Counter circuit
The next counter section operates similarly but is designed to count four quarters, single $1 coins (loonies), and single $2 coins (toonies). The circuit for the toonies is configured.
The circuit for the counter section includes a digital counting mechanism that...
