After basic peripheral interfaces with AVR, it's time to interface some sensors with it. In this tutorial we will interface Gas sensor MQ2 with Atmega 32 breakout. We will require a Smoke Sensor (MQ2...
In this tutorial we are going to discuss the Timer module of PIC18F4520.
First we will see what are timers, their working and later we will configure the PIC18F4520 timers to generate delay...
I am obsessed with numbers, are you? Examples in the demo are frivolous but the objective is
to display that numbers that matter on a tiny OLED from all over the internet(sort of)!
We will be...
In this tutorial we will see how to build a simple IOT Industrial Data Logger(IDL) to log the device temperature and current to AWS IOT and display it on Hornbill IO. The IDL connects to Wi-Fi and...
In the last tutorial we saw how to use the Arduino ESP32 AWS IOT library to configure an AWS client to subscribe/publish to a topic/thing. At the end of the tutorial we logged the temperature and humidity...
In the earlier tutorial we discussed how to setup AWS IOT for an Amazon user account. Now lets see how to use the Arduino esp32 AWS IOT library to communicate with AWS server.
AWS IOT for...
We have said several times that the ESP32 is feature rich. We will use two of the built-in components to build Hornbill Lights. In this tutorial we will make use of the built-in remote peripheral to...
Security of connected devices is of paramount concern. There are several possible ways to make the devices secure. One of the most essential and widely used options is to use end to end encryption....
We took a little break to build this two wheel drive (TWD) robot steered with the Blynk App. It was simple enough for a noon project. ESP32 is not just a WiFi or Bluetooth adapter, it was a capable...
