 Basic how to use H-bridge motor driver using bipolar transistor

Sunday, December 29th, 2013

A DC motor controller have many form, which is difficulty – easy to differently. Today, suggest building a simple two way DC motor control circuit. It is a H-Bridge that many popular and have high performance. That H-Bridge circuit, we will see that are most control circuit to moving of a robot. We can design […]

 Adjustable dc voltage regulator circuit using ic-7805

Friday, December 20th, 2013

I used to introduce many projects that use a IC-7805 or 78xx types, Today, it will modify from old circuit, IC-78xx series has many numbers. We can choose the desired voltage. such as “12V” should use IC-7812, but sometimes we don’t have this number with any reason. But we have too many IC-7805 number, since […]

 Simple one shot Touch Switch using IC4011

Wednesday, December 18th, 2013

Today we lets to play simple digital circuit. It is an One shot touch switch control. I use IC-4011 digital cmos is base of circuit. It is set form as flip-flops. The Logic “HI” at output when Your finger touch pad and is time delay for 3 second. Which we can determined this pulse time […]

 Simple three step level indicator

Tuesday, December 17th, 2013

Today we look at the concept of a simple level indicator circuit, which are built to be very small, can be displayed with LED 3 step. When see in the below circuit is very simple. We use a variable resistor(Potentiometer) with 3 unit only, making this the circuit cheap and easy. The Resistor values of […]

 Simple level voltage detector using LM741

Tuesday, December 17th, 2013

This is really Simple level voltage detector circuit. I like it so much because cause me know principle about comparator circuit form. As show in Figure below, We use LM741 OP-AMP(IC-741) highly popular is base of circuit. As video below. When we set all components to breadboard successfully. Suppose, we need to detects voltage 2-volts. […]
