binary-clock

Depends on the esp8266 Arduino environment

Depends on these libraries: the ESP8266 version of the ST7735 library millisecond precision clock library Timezone library ported to ESP8266 ESP8266 NTP client with millisecond precision rate adjustment of the local clock from offset measurements

Hardware:

• ESP8266 - processor
• ST7735 based LCD board

Pins (NodeMCU names):

• D5 - LCD SPI CLK
• D7 - LCD SPI MOSI
• D8 - LCD CS
• D2 - LCD RES
• D1 - LCD RS/DC
• 3.3V - LCD VCC
• GND - LCD GND

LCD + processor uses around 100mA on startup, ~25mA while running
