10 Ways to Ruin Your Mini-Max microcontroller (and lose $69)
Schematic Examples of some common mistakes
Problem: No current limiting resistor for LED I/O pins are logic level control signals only
Problem: I/O pins must be limited to 5 volts Always test voltage levels
Problem: Output pin is driven high by program but low by switch Set up inputs & outputs before connecting them
Problem: Battery is connected backwards! Be very careful with this
Problem: Two outputs connected together Watch your pin direction control registers (TRIS)
Problem: Input voltage exceeded Power supply must be between +6 and +15 volts
Problem: Vdd is +5 volts from internal voltage regulator Do not apply any other voltage to this pin
Problem: Vdd pin cannot power other circuits (except low power loads like sensors, etc.)
Problem: Too much current from one I/O port Use lower current or other ports
Problem: Pins are sensitive to static electricity Avoid touching pins
“Logical” Nomenclature What do you call the pin state? OFF FALSE ZERO LOW NO 0 VOLTS Vss GROUND ON TRUE NOT ZERO HIGH YES +5 VOLTS Vdd POSITIVE
