We have a collection of almost 500+ Arduino projects with Code, Circuit Diagram, and detailed explanations completely free for everyone to build and learn on their own. The IR sensor has a 3-pin ...

the following code makes Arduino to measure the speed of the moving object using two IR sensors and display the object speed in the I2C 16x2 LCD display. When the object triggers the first and second ...

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 ...

This project involves the development of a speed detection system using Arduino and IR sensors to monitor and alert traffic authorities about speeding violations on highways. The system calculates ...

I recently did tests with the IR sensor of a broken dvd player. The frenquencies of the signals are below 44kHz, wich means you can use the microphone input of your computer and audacity to record ...

It is built around Arduino Uno (Borad1), BC547 transistor (T1), infrared (IR) sensor modules (Module1 and Module2), and ... with a pre-programmed bootloader that allows you to upload a code to it ...

if the code received is 5A33C754, pin 13 will turn off. The circuit diagram for home automation is shown in Fig. 5. It is built around Arduino Pro Mini (Board2), IR sensor TSOP1738, NPN transistor ...

Voor dit kun je een Arduino Pro mini ATMEGA328P 3.3V 8M gebruiken. De LEDs kunnen met een weerstand van 100 Ohm aan de PWM pins worden gemaakt. Rood op 9, groen op 10, blauw op 5, en geel op 6. Maar ...

The robot uses a whopping 32 IR sensors to follow a black line across a concrete workshop floor, adjusting its path using a steering motor salvaged from a power wheelchair. An Arduino Mega Pro ...
