A digital counter whose logical output increments in steps on receiving clock pulses is used for a variety of counting and timing applications. It is at the heart of digital clock circuitry and other ...

Most water level indicators for water tanks are based on the number of LEDs that glow to indicate the corresponding level of water in the container. Here we present a digital water-level indicator. It ...

Even if you are designing a microcontroller-based LED display system, often it may calls for a manual option to control brightness of the LED display unit. On the otherhand, if it is based on discrete ...

When you need to connect amicrocontroller to a seven-segmentLED display, you can use a BCD(binary-coded-decimal)-to-seven-segmentdecoder. Figure 1 shows a typicalcircuit that uses a CD4511 to ...
