Car Battery Alarm
For Check battery in car, It use IC CA3140 and Transistor, Easy circuit.
circuit Car Battery Alarm by IC CA3140
For electricity pressure of automobile battery is important many factor. If be high class electricity tall pressure will have expired may cause the damage and electricity automobile system. I thinks Car Battery Alarm Circuit this may born the advantage certainly. When be born voltage of the battery expires. As a result will have an electric bell makes a noise to talk at one time come to. By pillar equipment that perform to check the level voltage this be IC CA3140 do in front compare with the level voltage well. Command give born electric bell loud sound follows to want. When see the circuit may not difficult exceed the attempt of friends , be lucky thank sir.
