“This pressure switch project is built using a piezoresistive transducer, LM358 OPAMP as comparator, and a relay. The circuit activate the relay when the pressure in a system exceed a given set-point. Basically, this switch can power ON or OFF …
“A sensor is a device that detects and responds to inputs from the physical environment. The input can be light, heat, motion, moisture, pressure, or any other environmental phenomena. Sensors are very important part of electronics, especially in Robotics and …
“So on my Youtube channel, many people ask how to combine two amplifiers into one. The first amplifier is used for satellite speakers and the second amplifier is used for subwoofer speakers. This amplifier installation configuration can be called Amplifer …
“Hi everyone. If you’re like me you, probably have a bunch of spare sensors lying around either from incomplete projects, or that you bought on a whim for some reason or another. I was inspired by Patrick Panikulam’s …
“In this project, we will make an automatic on-off water tap under $5 only. We will use an IR sensor and a water switch to make this automatic infrared water tap. No microcontroller is used to make this automatic infrared …
“Ever wanted to capture lightning on photo? Maybe this camera trigger will help you make incredible images. Sorry, it will not help you with the composition of your photo, the sensor sensitivity, shutter speed, aperture or whitebalance settings of your …
“DIY sensitive VLF METAL DETECTOR with Smartphone This Metal Detector detects a small metal coin at 25 cm and pot lid at 1m distance This metal detector is capable of detecting small metal objects at great distances. For example, a …
“This sound sensor with Relay driver shield for Arduino Nano can be used to develop sound-activated ON/OFF switch or other projects that require sound senor. LM358 op-amp is used as the amplifier, 1st op-amp amplifies the microphone signal, and …
“Rotary encoders are great for use in microcontroller projects as an input device but their performance is not very smooth and satisfactory. Also, having a lot of spare stepper motors around, I decided to give them a purpose. So if …
“My workshop is too bland. Despite the varnished, 80s-Esque wood planks that cover my walls, it lacks both color and of course: LEDs. Likewise, I often play music while soldering electronics. This got me thinking, could I combine both music …
