“A plethysmogram is a graph of blood volume vs time and a photoplethysmogram (PPG) uses light to measure blood volume, often with a finger probe. You can buy a pulse oximeter very cheaply on eBay. It uses photoplethysmography to measure …
“Control heat pumps manually or remotely via MQTT/Home Assistant. I love my heat pumps. They’re energy efficient and the fastest way to heat or cool any room. But I’ve always hated the remote controls that come with …
“It becomes tedious when multiple remotes of different or same appliance lie around and you have to find each one when needed like AC, TV, Music players. to overcome this problem we will make an arduino nano based universal remote …
“In this project I will solve one of the biggest problems I have with modern movies. The problem is that the conversation volume is way too low in comparison to the music volume. That is why I combined an Arduino …
“Control two LEDs with IR Remote, IR Receiver and Arduino. This project shows how to control two LEDs with IR Receiver and Arduino. An Infrared (IR) transmitter uses light to transmit signals to the IR receiver. The light is in …
“Hello all, I Hope you all are safe. I’m here with another project which you can build with very few components. In this writeup, I’m going to tell you, how you can make a Pulse Oximeter by using …
“An analogue proximity circuit built with active and passive components Hey there, thanks for coming around, I would love to walk you through on how to create a fully functional proximity sensor and understanding the logic behind it…They are …
“The remote control from my TV was worn out and beginning to malfunction. As it was an older model, a new remote could not be purchased. So, instead, I decided to make my own TV remote to replace it. In …
“In this instructable we’ll use the concept, reflection of infrared radiation to built a circuit which can detect the difference between black and white coloured surface. That might not sound interesting but later we can use that circuit to …
“Planck constant (h) is one of the fundamental physics constants and the most important constant in quantum mechanics. When I was studying physics years ago, I fall in love with Quantum Mechanics and now I have decided to conduct simple …
