Arduino Sleep Modes and How to use them to Save the Power
Power consumption is a critical issue for a device running continuously for a long time without being turned off. So to overcome this problem almost every controller comes with a sleep mode, which help developers to design electronic gadgets for optimal power consumption. Sleep mode puts the device in power saving mode by turning off the unused module.

OTA Programming (Over the Air) is a process which allows devices to upgrade their firmware or software wirelessly without any physical access. It uses wireless technology like Wi-Fi, Bluetooth, GPRS or 4G/3G rather than wired serial communication. OTA is used to reprogram the devices like microcontrollers, cellphones, computers, set-top box etc. OTA updates are generally sent for updating the software, resolving the bugs, adding some features etc. With the increasing use of IoT devices OTA is transferred using frequency bands having low data transmission rate (868 MHz, 900 MHz, 2400 MHz).

A Field-Programmable Gate Array is an integrated circuit silicon chip which has array of logic gates and this array can be programmed in the field i.e. the user can overwrite the existing configurations with its new defined configurations and can create their own digital circuit on field.

Here in this project we interface a 433MHz RF wireless module with STM32F103C8 microcontroller. The project is divided into two parts. The transmitter will be interfaced with STM32 and the receiver will be interfaced with Arduino UNO. There will be different circuit diagram and sketches for both transmitting as well receiving part.

In this tutorial it will be explained step by step with practical example. Here Hall sensor will be interfaced with Atmega16 microcontroller and One LED will be used to show the effect when magnet will be brought nearby the Hall Sensor.
This tutorial will help you in understanding PWM, its terminologies and how we can implement it using a microcontroller. In this tutorial we will be demonstrating PWM with AVR Atmega16 Microcontroller by varying the intensity of an LED.
