MAX7219 LED Matrix Display & IOT MCU ESP 01 DHT11
In this instructable we are going to learn how to monitor the temperature and the humidity measurements using the IOT-MCU/ESP-01-DHT11, MAX7219 LED matrix display.
ESP-01 OVERVIEW:
The ESP-01 is a small size black colored module with 1M memory.
The ESP8266 is a low-cost WiFi module with full TCP/IP stack.
The ESP8266 series are produced by Espressif Systems.
Operating voltage: 3.3V volts.
IOT-MCU ESP-01-DHT OVERVIEW:
Controller: ESP-01 / ESP-01S (To buy separately)

Can this made to work with displaying text from mqtt payloads? I have seen other projects but they needs other GPIO pins and so cant be done with this esp01 module.
