ULN2003 Stepper Motor Driver Board

Posted by
0
The ULN2003 is a high operating voltage and high current Darlington transistor array consisting of seven silicon NPN Darlington transistors. The main function of the ULN2003 is to provide a large current drive capability for the microcomputer, thereby achieving the current required to drive a stepper motor. Four pairs out of the seven pairs on this board are used.

A flame sensor is an electronic device that can detect flames (or high-temperature heat sources) in the environment and convert them into electrical signals. It’s widely used in fire early warning, safety protection, industrial control, and other fields. Its core function is to quickly determine whether a flame exists by identifying the unique physical characteristics of flames (such as light of specific wavelengths, temperature changes, etc.), and then trigger an alarm or link with other equipment (like fire-extinguishing devices, power-off systems, etc.).

The water level measurement of the HW-038 is achieved by measuring the amount of water through exposed parallel wires and traces to determine the water level. It can be connected to an Arduino development board to transmit the output analog signal to the Arduino, and a buzzer can also be connected to achieve the effect of water sensor alarm.

The GY-31 TCS230 is actually a color recognition module designed based on the TCS3200 chip. To put it simply, it is a little device that can "translate" colors into digital signals. The TCS3200 is the core chip, responsible for sensing colors and outputting frequency signals. The GY-31 is its "enclosure + driver board", making it convenient for us to use directly.
