Trouble with breadboards... any advice?

[LarryD]

Make up some breadboard helpers in advance.

Machine pin headers are easily to modify and easily plug into solderless breadboards.

Invest in at lease on resistor substitution board for tuning resistors.

Or make your own.

In situations where an accidental change in a potentiometer setting can cause catastrophic problems, change the potentiometer out for fixed resistors. Make a resistor substitution board ahead of time to use it to determine what the values of these resistors should be. All the standard resistor values (SMD 1026) have been placed on the substitution PCB. One end of all the resistors are common and would represent the wiper on a potentiometer. Female headers on the other side of the resistors w…
