Index of schematic symbols

Included here are schematic symbols for all the components that we’ll be working with this semester:

  • Battery
  • Resistor
  • Light-emitting diode (LED)
  • Capacitor
  • Potentiometer
  • Switch (x2)
  • Potentiometer & Capacitor again
  • Detail of DPST button (Switch)
  • Piezo element & Piezo buzzer
  • Arduino board
  • Servo motor

Fig 5. The way that I will typically represent the Arduino board in schematic diagrams. When doing so, I will label any various pin connections that need to be made between the Arduino and other components. Shown here are wires connected to the Arduino on the 5V and GROUND pins, as well as Digital pin 2. This was discussed in Tutorial 3. (Click to enlarge.)
