Simple Soft Latch Switch using Push-Button
Latching Toggle switches are one of the most popular kinds of switches, from their use by kids in basic electricity classes to their use in prototypes and more advanced products, they provide a familiar and reliable way to close or open a circuit. This makes them the go to switch for...
Continue ReadingGetting Started with the Arduino IoT Cloud
IoT is now mainstream. It has gone beyond the buzzword it used to be and several tools are being made available to makers to facilitate the development of solutions based on it. One of the newest IoT platforms is the Arduino IoT Cloud developed by our good friends at Arduino.cc. Today we...
Continue ReadingUsing ESP32’s Flash Memory for data storage
The ESP32 has about 4MB of internal flash memory and since the data stored within the flash memory is retained even when power is recycled, it becomes super useful for applications where you need to keep certain amount of data even after power off. For today's tutorial, we will learn how...

This 16x2 LCD shield for Arduino Nano includes various addons, like 5 Tactile Switches, 3 Trimmer Potentiometers, LM35 Temperature sensor and the 16x2 LCD itself. It's a compact shield designed to fit in small enclosures and it is intended to develop measuring devices like...
Continue ReadingUsing a 16×2 I2C LCD display with ESP32
A few weeks ago, we examined the features of ESP32 module and built a simple hello world program to get ourselves familiar with the board. Today, we will continue our exploration of the ESP32 on a higher level as we will look at how to interface a 16x2 LCD with it. Displays provide...

The circuit published here is an Inductive Proximity Sensor, which is used for non-contact detection of metallic objects. The circuit can be used for the detection of metal objects or as a positioning sensor. The TCA505 is used to design an inductive proximity switch that can detect a...
Continue ReadingUsing the BLE functionality of the ESP32
One of the most beautiful features which the ESP32 has over the ESP-12e is the fact that, asides the WiFi, it has two other communication modules onboard. The ESP32 comes with an onboard Classic Bluetooth and Bluetooth Low Energy modules. For today's tutorial, we will explore how the...
Continue ReadingESP32 Webserver Tutorial
One of the most interesting project we can build while learning to work with a WiFi Based board is a web Server. As we continue the journey to learn how to build projects with the ESP32, we will examine how to build a simple web Server with the ESP32. A Web server is essentially a...
