Microcontroller Voltmeter / Ammeter with LCD

The rectifier bridge voltage is determined by the U2 element; refer to its datasheet for the maximum voltage specifications. The minimum voltage at this pin should not fall below approximately 9V, or 6.5V if low-dropout type U2 and U3 voltage...

repair microcontroller circuit

The difference between these two ICs. A microcontroller is a specialized type of microprocessor designed to be self-sufficient and cost-effective, while a microprocessor is typically intended for general-purpose use, such as in personal computers (PCs). The microcontroller integrates several useful...
