yung source ko po ay 700mA lang ang kaya and need ko po ng 1.5A para mapagana yung solenoid lock.. 16F877a po ang PIC na gamit ko then kailangan ko po na pag nag-output ng voltage ang PIC mapagana nya yung solenoid lock. dahil mababa yung current na output ng MCU kaya di sya gumagana.. thanks po sa help..

ilang volts ang solenoid mo? kakailanganin mo ng external supply para sa solenoid...

you can only amplify current kung meron ka pang reserves, 700mA can only amplify up to 700mA unless merong external source or i-convert to lower voltage para tumaas ang current (using switching DC-DC techniques). gumamit na lang ng mas malaking source.
