I was a electronics hobbyist but now it becomes my profession. I'm also very passionate about advance electronics like IoT , smart electronic gadgets etc.
I've done a "bio-metric Data logging IoT device" projects and few automation projects with the help of arduino.
Also I made plenty of analog electronics projects like Modulator for up/down conversion link, Audio amplifiers, instrumentation amp for sensors, different types of filter, SCR controlled electronics and few lighting controller circuitry.
