PCA9685 16-Channel 12-Bit PWM Servo Driver can help a lot when there are insufficient PWM output pins for the MCU. The only condition is that the main control chip supports I2C communication, which means enabling the communication between the chip and PCA9685, so as to control multiple servos simultaneously.

Because the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flash cards and modes are 3.3V-only, many makers find that they need to perform level shifting/conversion to protect the 3.3V device from 5V.This 8-bit noninverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. VCCA should not exceed VCCB.

It has 8 keys which can be connected to any microcontroller or any interfacing kit directly. KEY is a small key pad designed to data entries for microcontroller board.The board has 10-pin header for 10-wire ribbon cable. By default the switch status would be pulled up, every time you press a key the corresponding switch header changes its state to the common header in the board.

Note: The color of the PCB may vary. However the circuit/pinout of the PCB will remain same.

Take a Look at the Updated Version of LiFi Here

Arduino Li-Fi Shield is a plug-and-play evaluation board for developing a wide array of visible light communication applications in consumer, wearable, industrial, medical and Internet of Things (IoT). Arduino Li-Fi Shield transfers data from one source to another through visible light without the flickering effect. Technically, 1‟s (LED on) and 0‟s (LED off) are modulated and then transmitted at very high speed.
