“The circuit is used a relay wthe arduino to control high voltage electronics.”
“I got an arduino a long time back to play around. Made some basic projects to start with. But never quite liked using it. No, arduino is awesomely good.”
“Let’s see if we can build an FPGA-based system. The biggest challenge is that everything involved is completely different from software and hardware design. It’s a new ball game!”
“I purchased many USB breadboard power supply from market but none of them fit on my bread board. Reason being non standard dimensions of breadboard. Holes are 2.54 mm apart, but total size is variable. Hence I decided to …
“One day a surface mounted power socket burned out in the room. The hot wire touched the ground pin. The socket turned black on the inside, but remained untouched on the outside. I’ve replaced it with a new one …
“This device is a small, portable ultrasonic range meter using an ATMega328 microcontroller, an ultrasonic module and a 4x20 LCD for ranging distances in meters and inches.”
“Designing and building a temperature controller for a soldering iron might seem unusual in these days of cheap Chinese-made soldering stations. In my case, I went even further, designing three different controllers. Crazy? Well, here’s the full story. “
“This project is an ESP8266-based “home automation” server that can control multiple RF-controlled electrical outlets on 315MHz and 434MHz. Using two receivers and two transmitters (one pair for each frequency), it can control most commonly available remote controlled …
“I learnt about Arduino 2 years ago.So I started playing around with simple stuff like LEDs,buttons,motors etc.Then I thought wouldn’t it be cool to connect to do stuff like displaying the day’s weather,stock …
