IR (Infrared Sensor) is an electronic instrument that is used to detect any type of obstacle/object & it is also used to detecting the black & white colour ...

What do you need to build an Arduino Speed Sensor. Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, and it is also very ...

An IR sensor module, which is used to detect fan’s blade to calculate the rpm, is connected to interrupt 0 means D2 pin of Arduino. Here we have used a stepper motor driver namely L293N module . IN1, ...

For first part, upload IR_decoder.ino code to Arduino. Connect the circuit as shown in Fig. 1. MP3 Vire (21-key) remote was used during testing. Compile and upload the code to Arduino. Now, point the ...

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. [… ...

So this inspired us to use GSM module for this project since the telecom network is widely spread within rural & urban area of the India. This system is used to monitor physical parameter like heart ...

If you have an Arduino that can act as a keyboard for a PC, the code almost writes itself. ... The serial communications is I2C and there’s a tiny optical sensor onboard along with an IR LED.
