If it does not work
Check your work for possible dry joints, bridges across adjacent tracks or soldering flux
residues that usually cause problems.
Check again all the external connections to and from the circuit to see if there is a mistake
there.
See that there are no components missing or inserted in the
wrong places.
Make sure that all the polarised components have been soldered
the right way round.
Make sure that the supply has the correct voltage and is connected the right way round to
your circuit.
Check your project for faulty or damaged components.
If your project still fails to work, please contact us for information about our Get-You-Going
service.
