In this article, we will learn ADC Reading with STM32 BluePill or other STM32 ICs. We are using CubeMx IDE and here is how we can configure the code for this purpose. Why do you need ADC? ADC is one of the fundamental features of microcontrollers. ADC helps read analog Read more
Those who worked with Arduino and built any GPRS or IoT project, are familiar with Adafruit_FONA Library. This library is handy for the Arduino platform to build any GSM, GPRS, or related project. But unfortunately, this library doesn’t work with ESP32 directly. And I had awful experiences with this issue. Read more
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
