Most trainer kits available in the market start showing wrong results after a few years of usage due to the aging of components. This ADC-DAC Trainer tool would work accurately for many more years.

Analog-to-digital converters (ADC) and digital-to-analog converters (DAC) are integral parts of data processing and widely used industrial and household electronic devices. Different conversion methods include resistor ladder, binary weightage, and cascaded op-amp.

The project uses Arduino IDE as the software development platform, so the trainees can perform ADC and DAC experiments as well as get an idea about the configurations of ADC and DAC in Arduino. The main advantages of Arduino software are easy editing and debugging.

ADC-DAC Trainer Circuit Diagram

Fig. 1 shows the circuit diagram of the DAC-ADC trainer. The circuit consists of an ATmega328P microcontroller interfaced with a 20×4 LCD module and I2C module, 8-bit LED digital word display/generator, voltage regulator, voltage divider circuit for ADC input, and nine switching diodes, besides some discrete components such as resistors and capacitors.

The ATmega328P microcontroller used in Arduino Uno has six inbuilt ADCs with 10-bit resolution and six DACs with an 8-bit resolution that uses pulse width modulation (PWM) for DAC conversion. The Arduino IDE is known to be the most popular and cost-effective software development platform.
