I cant find mm74c in multisim too. Datasheets, Manuals or Parts. Hi guys i built the circuit successfully however it doesnt reset at 60 senconds and instead continues to 99 does anyone have any soulutions. Rotary switch S1 is used to select the different time periods at the output of the astable multivibrator IC1. Like that all the terminals of the IC is connected to the respective terminals of the 7-segment display.
I was made this projects. Wat will be the cost of tis project.! Can u tell me which tansistor to use? To participate you need to register. Hi Naish use the following data for your connections http: If you want to stop the clock, close S2. And also this is a suitable hobby project for newbies. Articles Top Articles Search resources. When monostable circuit generates output, astable mode timer starts giving pulses to the counter module. How are the resistors connected to the 7-segments?
You can buy the kit at BuildCircuit store. So, what i do or anything wrong in project. The circuit works off a 5V power supply.
Dark sensor on breadboard September 8, TO know more about the terminals of the 7-segment display check this link http: How does the IC work? But there are not any effect of LDR on display. Pin 3 of monostable circuit has been connected to pin 4 of astable timer. Hi Kkak52, You have to add pull-down resistors at the reset, latch and diplay select inputs.
I have Made digital stopwatch using this cct. Your email address will not be published. Auto-Detection l Bluetooth l Smart Multimeter. Jc switch December 18, Any idea how to fix this. Powering up 3 digit object counter with USB cable.
For more circuits, please check our category on Clocking and Timer Circuits. My soldering is also propered.

Output of 5v from ac to dc wall mobile charger something says 5v mA output 2. Most linear regulators have only a series-pass transistor to feed current to xatasheet load. Satasheet IC1 has a minimum input voltage of 7. And what exactly happens if one regulator is inevitably a little higher in voltage than the other? This difference between the input and output voltage is released as heat.
