In this article, we are going to make a Digital Clock using a PIC microcontroller & RTC DS1307. Here we can use a suitable PIC microcontroller that is available in the market or in our lab. I think PIC16F73 will be the best one. With this microcontroller, we’ll interface RTC Read more…
Noise or garbage on the LCD display is a very common problem to us who works with electronics. Almost everyone experienced this problem in their work-life at least once, & I? maybe over 1000 times. There are multiple reasons for this garbage problem and also there is a solution to Read more…
We all know about voltmeters. Besides multimeters, there are some panel meters that show voltage, current, etc. Making such an AC voltmeter is sometimes becomes very helpful. Here in this article, we are going to learn how we can make our own single-phase AC voltmeter using a PIC16F76 micro-controller and Read more…
EEPROM is a very fundamental feature of Arduino and it has internal EEPROM for this purpose. But sometimes, we need some more to use. In that situation, some dedicated EEPROM ICs like 24Cxxx ICs. In this article, we are going to interface external EEPROM with Arduino. So let’s start! EEPROM Read more…
In this article, we are going to make a simple Analog Temperature Controller using OP-Amp and Relay. This is a basic article, that can be used as a reference for large designs. If you understand it clearly, you can apply it in other controls. So let’s start! You can this Read more…
For an incubator, a temperature controller is the main control unit. There are many temperature controllers in the market. But here is a simple one, I think the most simple one that you can make yourself. The circuit required no external power supply as it uses a simple capacitor power Read more…
Sometimes making a high amp regulator become very complex using linear regulator ICs. But using a buck converter can be very easy if the circuit work is simplified. Especially for motor-type loads. In this article, we will make a simple motor regulator using buck converter utilizing N-Channel MOSFET and NE555 Read more…
When it comes to mind to use a DC/DC converter the first converter that comes to mind is the BUCK converter. There are lots of designs online as well as dedicated ICs for this purpose. But most of these are high side P-MOS based. In high-side P-MOS-based circuits, the gate Read more…
Remote Controlled Fan light switch is very popular in the market also very demanded too. Besides these, the switch is very helpful for disabled persons and children too as there is no need to touch the switch physically. The switch can be operated far from 30ft on average depending on Read more…
In the previous article, we have seen how we can make an analog voltage stabilizer. We have seen that the circuit was pretty complex, like a bird’s nest. In this article, we are going to learn how we can use a micro-controller for that purpose and make a smart voltage Read more…
