Temper- Sleek Temperature Sensor Built on Esp8266

Temper: Sleek Temperature Sensor Built on Esp8266

Meet Temper, a compact, low power temperature sensor based on ESP8266 and SHT30 with a large 13×7 pixel led display. It accesses WiFi periodically to display temperature and humidity data as well as battery percentage via the MQTT protocol. The device’s display uses three 74HC595 + 7 n-fets,  TP4054 to handle battery charging through a USB and MCP1700T LDO to power the ESP. For WiFi setup, Temper …

Minimalist IoT Clock (using ESP8266, Adafruit.io, IFTTT, and Arduino IDE)

In this tutorial I show how you can make a minimalist clock synchronized with the internet. I tested it with two different ESP8266 based boards: Firebeetle and NodeMCU. The microcontroller gets current time from a Google server, and displays it on a NeoPixel LED ring. It also receives current weather data from WeatherUnderground, using IFTTT …
