The full indicator Led glows when 9 is displayed on the seven segment display. To check display count when cars leave the parking lot: An obstacle is brought near Proximity 2 until the led on the ...

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 ...

For applications not requiring fast conversion,a single circuit that can performboth conversions proves adequate. Onesuch circuit (Figure 1 ) utilizes up/downcounters to obtain the desired results.
