Arduino pulse sensors have a small infrared LED that is placed on a finger ... Sensors like this are useful for an array of projects, from DIY remote control cars to digital measuring tools.

We’ve featured loads of IR Arduino projects and they are all exciting and unique. The projects spring from a specific need or problem where a custom infrared remote control is the solution.

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

A typical Arduino microcontroller board is pretty small ... a motor/stepper driver, sensors, OLED, Bluetooth, an amplifier, and more. Potential projects include remote control of household ...

Here’s a photo of my prototype: Because the design is based on the IR sensor module ... with the following Arduino Sketch (code) to read decoded values in hex through the Arduino Serial Monitor (see ...

It actually uses the motor and wheels from a small toy car ... and a gyroscopic sensor. This has neither. The black PCB seen to the right of the robot is an IR reflectance sensor.
