# Simple Arduino Projects for Beginners- Real Time Clock with Alarm

We have started Arduino programming guide and project series. In our last article we had a general overview of Arduino and Getting started with Arduino guide by Mr.Jaseem. We received many appreciations form readers and I would like to thank them all. So to make you happier with Arduino circuits here I’m coming with another…

# Simple 4026 Manual Digital Counter Circuit with Reset and Pause

In our normal practical life, we may face circumstances where we need a digital event counter in order to count certain events. Here I will give you some examples: people counter circuit in an auditorium, to count the number of products in a godown, to calculate an athlete’s performance and above all, all the digital…

# Binary Up Counter Circuit with working animation and simulation video

Here we are going to discuss about an Asynchronous 4 Bit Binary Up Counter, a circuit made up of several J-K flip-flops cascaded to generate four bits counting sequence. An up counter is basically a digital counting circuit which counts up in an incremental mode. Here we have given the simple counting circuit setup using…

# Ring Counter Circuit Working Principle with Animation and Video

Digital counters have several applications in electronics circuits. Counters in digital electronics are used at different situations. Here we are going to deliver the idea of a Ring counter circuit, which is a register counter. Working animation and circuit simulation video of ring counter are also given along with this article. A ring counter is formed…

# Johnson digital counter circuit diagram using D flip flop 7474 (3 bit/4 bit) with animation/ simulation

The Johnson digital counter or Twisted Ring Counter is a synchronous shift register with feedback from the inverted output (Q’) of the last flip-flop. Q’ of the last flip flop is connected back to the input D of the first flip-flop. This inversion of Q before it is fed back to input D causes the counter…
