Arduino as AVR Programmer

For my project I need two Arduino boards, but I have only one Arduino Mega 2560 board (refer Fig. 1). I can either buy an Arduino Uno board (that costs approx. Rs. 1400 in India) or I can make an Arduino board using a fresh ATmega328/ATmega328P chip. Suppose you have an Arduino board that is built on ATmega328P or ATMega8A-PU chip and, due to some reasons, the chip has gone bad (like in my case). You can bu ...

Dual sharing RTC

Necessity I have an old window AC at my lab, situated at the terrace. The AC needs to be run intermittently more so often when I’m out of the station and the lab PC needs to be cooled down during the intense noon time when the temperature shoots 35+ degree centigrade irrespective of summer or winter. Of course, the thermostat works! But it needs to be changed continuously else it will keep on running for pr ...

Getting started with NodeMCU development board for IoT

Since Internet of Things (IoT) projects are now quite popular, I recently bought a NodeMCU board to try IoT application development. The NodeMCU development board is an open source board based on ESP8266EX microcontroller with integrated Wi-Fi transceiver. Uploading programs to NodeMCU from any computer via microUSB port is very easy as it supports several programing languages. This makes NodeMCU a smart ch ...

Controlling Arduino with Raspberry Pi using pyFirmata

Controlling Arduino with Raspberry Pi using pyFirmata Although Raspberry Pi and Arduino are two different hardware in terms of their applications and structure, but they both are considered as two competing open source hardware platforms. They both have very strong community and support. Today we will slightly change things, and show you how we can take advantage of both of them. If you have both Arduino an ...
