Circuit diagram for this Analog Speedometer is simple ... 16x2 LCD is connected at following analog pins of Arduino. A 2.2k resistor is used to set the brightness of LCD. An IR sensor module, which is ...

GND Should be connected to the ground of the Arduino. An IR proximity sensor works by ... LED turns on when the circuit is triggered. This board also has a comparator Op-amp that is responsible for ...

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 ...

Arduino Uno : Arduino/Genuino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs ... It'll ...

This is a project circuit which helps to a person in the driving seat and gives an alarm if there is any obstacle or a wall while parking or while driving in reverse. Here, The IR sensor will detect ...

The LDR is connected to a voltage divider circuit to produce an analog signal proportional to the light intensity. The analog signal is read by the Arduino via pin A0. The program compares the sensor ...

The digital signal output to be detected (usually marked as DO in the module) is applied to D2 input of the Arduino. Analog output (marked as AO) from the module is not used here. Sensor-head of ...

The project was designed for Arduino system with the integration of infrared remote control receiver. The use of Arduino system proves to be working fine with any RC5 format remote control. The serial ...
