TM1637 4-Digit Digital Display Module

This module is a three way switch ( COM, NO and NC ) that uses the intensity of the ambient light to control directly the load at the output. Its adjustment potentiometer allows changing the sensitivity and setting the start threshold of the relay. The relay is energized when it is darker than the threshold.

It is the freshest serial LCD from SparkFun. Similarly to other SparkFun LCD screens it is put on single board with a microcontroller, however in contrast to the other screens in our offer (SP027 and SP028) it is based on PIC16F88 rather than ATmega328.

The ADS1115 is an external 16-bit ADC + a built-in programmable gain amplifier (or PGA), which can be very useful for certain Arduino and ESP8266 projects. This is ideal when more resolution or more analogue pins are required. You get better accuracy, as well as relieving the processor of this burden.

This E27 bulb adapter will allow you to control its on and off by WiFi and to control your lamps by the free eWeLink APP, with which you can create routines and scenes, by IFTTT, or also by voice assistants such as Alexa or Google Home.
