The choice of driving a stepper motor or AC motor means including different types of driver circuits. Learn More The sensing temperature range of thermistors is an advantage over some of the sensors we'll look at later. Well examine how to design a PCB with a power amplifier. Its obvious that only electric actuators are directly powered by an electronics circuit. Instead of sensing real-time variables, actuators turn energy input into physical movements. Often, an op-amp is needed to amplify the analog value of the temperature before being fed into the ADC pin of the microcontroller. The connector pinout needs to be changed completely to support our two digital protocols: SPI and I2C. Instead using two source voltages to power different analog temperature sensors, we'll use I2C and SPI buses on the board to interface with digital temperature sensors. We will also build a pair of hostmicrocontroller boardsto collect data and evaluate thesensorsagainst each other. The card edge connector will be a TE 5650118-3, which offers 12 pins of connectivity.
