In this article, we are going to see how we can store String in the EEPROM of a microcontroller and recall those strings to print on display or use it for different purposes. Usually, we use ROM as the main memory and RAM for variables. But this technique will save Read more…
In this article, we are going to learn about Interfacing External EEPROM with a PIC microcontroller. All the microcontrollers do not have EEPROM but sometimes, we need to save some information in EEPROM while the MCU does not have any. In that case, external EEPROM is the only solution. So Read more…
This is a very common error to them who works with microcontrollers. In this article, I’ll show you ways to solve this Not Enough ROM/RAM error. The high-level MCUs are capable of handling the memory mapping properly. But the lower level MCUs are not especially PIC10F,12F,16F series. But we need Read more…
In this article, we are going to learn how to make a simple voltage protector for your appliances. A small device can save lots of money, saving your appliances from voltage spike/surge/sag and unacceptable voltage range. So let’s make it! What is spike/surge/sag? Usually, your home supply voltage is either Read more…
In this article, we are going to make a Simple Component Detector using PIC16F877A microcontroller. Using the basic working principles of different semiconductors, we can identify the devices. Here, we are using some simple and basic techniques, using these techniques, we can measure/detect resistors, diodes, LEDs, transistors, MOSFETs, Logic Gates, Read more…
This is a productive post with a voltage stabilizer circuit with 4 relays. A voltage stabilizer is sometimes becomes essential for our appliances if the supply voltage is not stable. Here in this post, you’ll find a product that can help you. Why do we need a voltage stabilizer? Our Read more…
In this article, we are going to make a 6V lead-acid battery charger circuit in different ways. 6V lead-acid batteries were very common decades ago when portable emergency lanterns were very popular. But still, these batteries are being used in various devices. Sometimes, we need our custom battery charger circuit Read more…
In this article, we are going to make a complete digital clock with DS3231 and a PIC microcontroller. The RTC ds3231 is extremely accurate as a clock. We are going to use this RTC for our Clock come calendar with temperature and showing these values on Seven-Segment displays. This article Read more…
In this article, we are going to make a Digital Clock with PIC16F676 and RTC DS1307. Seven Segment Displays will be used as our display. Using this small microcontroller, we can make our Date and Time clock. For this, shift registers will be used to extend the pins and to Read more…
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…
