Scoreboard Display
This circuit is live in Circuit Canvas. Open it to explore every part and wire, or make your own copy to change values, swap parts and build your own version. Free, right in your browser.
A simple project that counts the number of times you've pressed the button. Can be used as a scoreboard display for a game. Or to keep tracks of things like how many cups of coffee you've had today.
Scoreboard Display Schematic
The CD4026 is a pulse counter that outputs signals to control a 7-segment to display the result. For each button press, the CD4026 counts up.
The resistors R1-R7 sets the current for the LED segments in the display. R8 is there to keep the counter input LOW when the pushbutton is not pressed.

How to Build the Scoreboard Display
This circuit has a lot of connections and it's easy to make a mistake. Here's an example of how you can build this circuit on a breadboard:
Make it your own
Every circuit here is a live project in Circuit Canvas, not just a picture. Copy this one and change a value, swap a part or move it to a stripboard: the schematic and the breadboard layout are linked, so a part added to one appears in the other.
Or start from a blank canvas and draw your own circuit, with thousands of ready-made parts.
