When you are working with battery depending low power-consuming circuits, then you may need this innovative power switch. The concept is to save energy while the device is not operating but the battery is connected. Why we need to save energy: We use electricity almost all the time. In some Read more…
DC motor is very common and we use it for different purposes. But problem is, when used with a sensitive circuit, this DC motor creates problems in the working of the circuits. Such as communication disturbed, signal distortion, noise in amplifiers, and so on. In this article, we are going 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…
Sometimes, you may need to make a DC/DC converter with minor components that can handle small loads. In this article, we are going to make something like that. This DC/DC converter using transistor has only a few components and can handle small loads or higher voltages, suitable to use with Read more…
