If you think this project is too simple to be useful, please see the table of components which it can be used to test and think again! Home | Map | Projects | Construction | Soldering | Study | Components | 555 | Symbols | FAQ | Links Simple Component and Continuity Tester A kit for this project is available from RSH Electronics . Download PDF version of this page This simple project may be used for testing components , as well as checking circuit board tracks, wires and connections for continuity (conduction). It tries to pass a small current through the item being tested and the LED will light brightly, dimly or not at all according to the resistance of the item: LED bright means the resistance is low , less than about 1k LED dim means the resistance is medium , a few k LED off means the resistance is high , more than about 10k When not in use the 9V PP3 battery should be unclipped or the crocodile clips attached to a piece of card or plastic to prevent them touching. You could add an on-off switch in the red wire from the battery clip and this may be the best option if you mount the simple tester in a box. Parts Required resistor: 390 red LED 5mm diameter, standard type battery clip for 9V PP3 crocodile clips: miniature red and black stripboard: 5 rows × 7 holes Stripboard Layout Testing stripboard, PCB tracks, wires and connections Simple Component and Continuity Tester http://www.kpsec.freeuk.com/projects/simplet.htm 1 of 4 3/9/2009 11:30 PM
