Add a timer to pulse the decade counter.

For the split second that the timer supplies voltage to thea random LED is lit up. It has 16 pins and looks like any other 16 pin integrated circuit. A 16 DIL pin Decade Counter with 10 decoded outputs and inputs including, clock, reset, and clock inhibit. I added the source current graph to the answer. The diagram shows the sink current. If that works, and you want to make them brighter, you’ll need to either find a that has greater current ratings on the output pins or add some transistors.

Click ask a question to be the first. You’ve verified that LED 0 is connected to pin 3, 1 to 2, 2 to 4, etc. Curd You are correct, I had not paid attention to the schematic properly.

Decade counter (4017B)

Max quiescent current at 5V: Add to Cart Details. The B is an integrated circuit datazheet has been designed to count pulses. Delivery times vary for international orders depending on the service selected and the destination. It datasneet quite possible that you need more current than the can handle. Your schematic doesn’t match the “drawing. The LEDs won’t be as bright, but it might be within your ‘s current sinking ability and at least allow you to determine if things are working correctly.

Thank you for your interest in this question. Be the first to review this product. This is essentially what I’m trying to create: Decade counter B How do you rate this product?

However the LED’s flash 4071b random orders. You must have JavaScript enabled in your browser to utilize the functionality of this website. That’s equivalent to 1.

In this circuit a reset switch has been added. As Tony mentions in his answer, if the LEDs have a typical forward voltage of 2 to 2.

As long as the clock inhibit is held low, upon a rising edge of the clock pin the output will count up from zero, one number at a time for each rising edge on the clock pin. Max clock frequency at 5V: UK Deliveries If you live daatasheet the UK mainland and don’t have any large materials or lithium batteries in your order it will cost 3.

If the goods are not in stock we will endeavour to contact you as soon as possible to discuss a dispatch date. Typical output drive at 5V: Drawing shows a pushbutton between Dataxheet and the actual power supply that is not on the schematic.

Is that switch actually there? Write Your Own Review You’re reviewing: Rest of the world These orders are sent via UPS, and the cost is dependant on the service you choose at checkout.

Problem with timer and counter Ask Question. The wires from the battery snap and also the ones datssheet the toggle switch are fed through small holes in the PCB. Would you like to answer one of these unanswered questions instead? Linking the B ICs together in this way allows for long interval timers to be made.

If it’s normally open, then that’s your problem. A number of B IC circuits can be connected together by connecting pin 10 divide by 10 pin to the input on the next B IC. I’m attempting to make a circuit that flashes each LED sequentially.

These charges are usually billed to you directly from UPS.

Decade counter (B)

We do not charge a packaging or handling fee for this service, and you will receive an email when your order has been processed, you can collect half an hour after receipt of this email. If so, is it normally closed or normally open?

Also note that the timer never actually “stops” supplying voltage; it supplies a high voltage, and then it supplies a low datashset, repeatedly. You can figure out the resistor value to use by rearranging Ohm’s law: Counters such as the B are cheap and yet surprisingly useful. IgnacioVazquez-Abrams I didn’t know that. Any idea what’s going wrong here? Per Curd’s comment, I am also including the source current diagram from the datasyeet.

I didn’t include any of the switches from the picture.
