5Pcs MAX7219 Red 8 Bit Digital Tube LED Display Module For Arduino MCU Description: MAX7219 is an integrated serial input / output common-cathode display drivers, which connects the microprocessor and 8 bit 7-segment digital LED display, you can also connect a bar graph display or 64 separate LED. Includes an on-chip type B BCD encoders, multi-channel scanning loop, segment word driver, but also a 8x8 static RAM that stores each data. Only one external register is used to set the current of each LED segment. A convenient four-wire serial interface can connect all common microprocessor. Each data can be addressed in the update without rewriting all displays. MAX7219 also allows the user to select each data encoding or no coding. The entire device includes a 150μA low-power shutdown mode, analog and digital brightness control, a scan-limit register allows the user to display 1-8 bit data, there is an all LED light detection mode. Feature: 0.36 inch Common cathode Only need three IO ports can drive 8 bit digital tube The module compatible of 5V / 3.3V microcontroller (51 / AVR / STM32...) PCV board four corners of the fixed copper stud, which can effectively precent short circuit accidents happen Wiring instructions (a program, for example, you can pick any IO port definition can be modified in the program): VCC to 5V, GND to GND, DIN to P00, CLK to P02, CS to P01 Note: VCC and GND do not reversed, it would burn the chip. 51 MCU P0 port requires pull-up resistor, if your device does not have a pull-up resistor can be connected to other ports data lines. Package included: 5 x MAX7219 8 bit digital tube module 20 x Copper pillar 20 x Screws

5pcs TM1637 6-Bits Tube LED Display Key Scan Module DC 3.3V To 5V Digital IIC Interface Package contains 1 X item of the smallest listed variant.

5Pcs Infrared Obstacle Avoidance Sensor For Arduino Smart Car Robot Description: The sensor module light is adaptable to the environment, the working voltage of 3.3 V to 5 V. It has a pair of infrared transmitting and receiving tube, when detecting direction meet with obstacles (reflecting surface), reflected infrared receiving by the tube. After the comparator circuit processing, green indicator will light up, at the same time the signal output interface output a digital signal (a low level signal), can be adjust the detection distance through the potentiometer knob, effective distance range 2 ~ 80 cm, easy to assemble and use. So it can be widely used in robot obstacle avoidance, obstacle avoidance car, line count, and so on many occasions. Package included: 5 x Arduino obstacle avoidance sensor

5Pcs CD4017 Light Water Kit Voice Control Water Lamp Electronic DIY Kit Feature: The circuit is easy to install, just need to correct welding, after completed soldering, you can normally use it. The microphone turn the external sound into a current signal, amplified by a transistor Q1 into the integrated circuit U1. U1 has 10 output terminal, respectively control an LED light tube. The volume and frequency of the sound control the brightness and the number of the light emitting brightness of the luminotron. The louder the sound, the brighter the LED, the more number of light. Note: We don't offer any manuals, only has schematic, please note about this before you buy it, sorry for the inconvenience. Package included: 5 x CD4017 Light Water Kit
