Made by Atmel (same as Arduino)
Small and cheap
Uses less power
Not all Arduino functions would work
Can use software communication features even hardware don’t
Distance via Ultra Sound
Just use Digital GPIO pin
And turn DigitalWrite LOW/HIGH
Can be used both:
- Raspberry - HDMI
- Arduino - SPI
Please Use Quality ones

MQTT (Message Queuing Telemetry Transport) is an ISO standard (ISO/IEC PRF 20922)
publish-subscribe-based messaging protocol. It works on top of the TCP/IP protocol. It is
designed for connections with remote locations where a "small code footprint" is required or
the network bandwidth is limited. The publish-subscribe messaging pattern requires a

“Same trends that have been true
for decades. Higher levels of
integration, especially with new
kinds of IO like RF (ESP-12/32,
for example), more memory of
various types, faster clocks,
