Toggle Counter is a educational binary code to decimal tool. Enter a binary value on the toggle switches and the 7-segment LED display shows the decimal value equivalent.
Toggle Counter has a recessed back plate to prevent scratches from the screws to the resting surface.
Toggle Counter is powered by two internal AA batteries. When no activity on the toggle switches is detected a periodic beep is emitted to alert the user to help save battery life.
The electronics consist of an Arduino Nano, DC-DC converter, a 7-segment LED display, LEDs, and toggle switches. The wiring was manual completely as for a simple project designing a PCB would be more time consuming.
