Hi welcome to Elonics. In this episode, we’ll see how to make an LDR based light sensor circuit while simultaneously learning how it works. We’ll also see how to convert this into a darkness sensing circuit. So, lets started. For circuit diagram or any other information please refer to the description. These are LDRs. Short
Parts needed. 4 by 6 pref board, 2 by 4 female header, and male header pins. Place female header pin to solder. Solder one pin to check position. Then solder the rest of the pins. Pull out a pin from the male header. Save the linking plastic for later. Bend the pin to 90 degrees..
Hi, Welcome to Elonics. In this video, we’ll make an InfraRed proximity sensor circuit on a breadboard while simultaneously learning how it works. Also the detecting range can be configured by adjusting the potentiometer. Our objective is to turn on LED or any other electronic device whenever any obstacle comes nearer than a specific distance.
Hi Gang! I’ve been asked a lot how to make an amplifier for a crystal radio, one that plays loudly on a speaker. As you can see I got a little fancy and made a permanent one in this jar. I’ll show you how I made it step-by-step, and how you can make one too.
