Practical—creating a cloud proximity detector
In this practical, we will create a unique cloud proximity detector using the Keyestudio Arduino Super Starter Kit, which integrates with AWS IoT services. The project will use a combination of sensors, actuators, and cloud services. By the end of this practical, you will understand the benefits of utilizing AWS for IoT networks and learn how to optimize costs, resiliency, and low latency in your deployments.
Assembling the circuit
First, we will assemble the hardware of the project:
- Connect the NodeMCU ESP-32S, IR proximity sensor, piezo buzzer, and WS2812 RGB LED strip as shown here:
Figure 7.7 – Wire-up diagram of the hardware of the project
- Connect the IR proximity sensor to the breadboard. Connect the VCC pin to the 3.3V output on the NodeMCU, the GND pin to GND, and the data pin to GPIO 36 (also known as VP or ADC1_CH0) on the NodeMCU.
- Connect the RGB LED strip...
