LM393 Voltage Comparator Module Features The LM393 amplifier module can be used to compare an input voltage with a predetermined voltage level. The LM393 IC contains 2 op-amps that are completely independent. In LM393 comparator module, only one of the op-amps is used and the other is not connected. The module compares input voltage with the desired voltage level, and produces a digital output. The voltage level can be any value between the module positive and negative supply voltages. This voltage lev...

GY-31 TCS3200 Color Sensor Features The TCS3200 color sensor uses 64 photodiodes to detect color. The output of this sensor is a square wave. Color intensity is obtained directly from the frequency of the square wave. These 64 photodiodes consist of 16 diodes with red filter, 16 diodes with green filter, 16 diodes with blue filter and 16 transparent photodiodes without filter. All 16 diodes of each type are connected in parallel. To detect any color, the photodiodes corresponding to that color are activ...

BYGH403 1.65A Stepper Motor Features Stepper motors are one of the most widely used motors in robotics and electronics. These motors are actually the same as DC motors that move in discrete steps. They have multiple coils called "phases". By supplying each phase in sequence, the motor will rotate one step (the angle of each step for each motor is specified in its datasheet). with controlling these pulses precisely, you can achieve very precise speed control.Applications:CNC3D printersInkjet printersSca...
