4 digit sensor counter using mcs51-AT89C1051

Posted: 19 Feb 2013 09:01 PM PST

This is a counter circuit that I would like to you view an another form of concept. The most counter circuit that is often used in industrial applications such as object detection and counting. This project uses a sensor to detect objects that pass through, then the number increases or decreases by one and shown is the display digits. The most counter products are often priced quite expensive. However, it is recommended to create a counter that ‘s affordable. It’s accuracy work effectively. Since the circuit is controled with the micro controller IC. Special feature -Can count the number of 4 digit, or counting from 1 to 9999. -There are function to count up or count down mode. -Sensors are used to detect objects is infrared sensor. –Which is the transmitter and the receiver included in the same body both opposite and Between the middle as gap, Makes object is [...]

Digital timer controller 0-99 second using PIC16C56

Posted: 19 Feb 2013 04:28 AM PST

After we had a timer in various forms. For example : the RC circuits or using IC generat and frequency divider. This time we try to run some microcontroller IC. The advantage of it is that we can assign different effects to it, and many other applications. So we recommend take a look at this Digital timer controller according to your needs or not. Special feature -Set the time from 0-99 seconds or 0-99 minutes. -There is EEprom-IC helps to keep the program, without the need for power supply. - Can be added or Delete times. At set the time. - Used with other devices such as vending machines, etc. - Show the times while the countdown set the time. How the circuit works As Figure 1 When 12 volts DC voltage into the point DC in 12V next wire is connected to a bridge circuit (D1-D4) which them is [...]
