FIRMWARE ASSIGNMENT GREENDZINE Problem statement: Develop the code in Arduino to interface an LM35 temperature sensor (Assume the sensor is connected to Arduino Analog pin A0) with an Arduino Uno and ...

The aim of this project is to develop a circuit that can count the number of people entering and exiting a room using two Infrared (IR) sensors connected to an Arduino UNO. This bidirectional counter ...

We’ve all been there. Your current project has hit a wall, or the next step will take days to complete, and you need something to do in the meantime. So you start a project that you envision will fit ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

[Edward], creator of the Cave Pearl project, an underwater data logger, needed a way to measure temperature with a microcontroller. Normally, this problem is most easily solved by throwing a ...

We build this Arduino-based Digital Thermometer for temperature measurement applications. Thermometers have been useful for temperature measurement for a long time. A digital thermometer is an ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

In our daily lives, we use thermometers on various occasions and for various purposes, from medical needs to repair and diagnostic purposes. As you know there are different types of thermometers, and ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...
