Description: The Basic Counter is a simple and fun electronics kit that you can use to build a counter that can count up to 9999.
How many times has your fridge opened, your dog barked, sump pump pumped or your widget machine widgeted? With the Basic Counter, you can find out!
The Basic Counter uses a switch (or sensor) as the input for counting. The switch will basically break or make a connection between two screw terminals on the board. Every time that the switch is triggered, the count is incremented by one. The Basic Counter will work with both normally open and normally closed switches. Some sensors that produce a full on or off when triggered can also be used.
The count is shown on a bright four digit seven segment display. The kit comes with a coin cell battery, so it can be installed in remote locations. To save battery power, the display goes to sleep after about 15 seconds, and every time the count is incremented the display lights up. There is also an onboard button to wake the display and show the current count. The wake button does not trigger another increment.
Optionally, there is jumper to keep the display from going to sleep and also screw terminals to connect an external power source, such as a wall adapter for more permanent installations.
