What you need

• TO-92 Triode Kit
• Arduino Uno
• Breadboard
• Soldering Connections
• Multimeter

Steps

1. Check the type of triode needed for your project by consulting the circuit documentation.
2. Connect the triode pins Emitter (E), Base (B) and Collector (C) to the breadboard following the datasheet specifications.
3. Connect the Arduino Uno to the triode pins through appropriate resistors to protect the Arduino chip.
4. Verify with a multimeter that the connections are correct and secure.
5. Write the Arduino sketch to control the voltage applied to the triode base, modifying the digital output.
6. Upload the sketch to your Arduino Uno.
7. Observe the circuit behavior with an oscilloscope or multimeter.
8. Adjust the resistors and input values as needed to optimize the triode function.

Example code

void setup() {
  pinMode(2, OUTPUT);
}

void loop() {
  digitalWrite(2, HIGH);
  delay(1000);
  digitalWrite(2, LOW);
  delay(1000);
}

Mini project

Create a simple audio amplifier using one of the triodes in the kit. Connect the microphone to an audio signal source and use the Arduino to receive the data.

Common mistakes

• Using resistors that are too low in value which can damage the triode.
• Failing to properly verify the polarity of the triode pins.
• Ignoring the voltage and current specifications in the datasheet.
• Not testing the circuit before uploading the Arduino sketch.

Recommended accessories

• Variable resistors
• Portable oscilloscope
• Power column for testing audio
• USB rechargeable battery
