Arduino Project 20-Arduino Joystick and stepper motor tutorial
In this tutorial, we will see how to use Arduino with a stepper motor and a joystick. To control the stepper motor we will use the driver control board that can drive up to about 750mA per port, so it is perfect to be used with this motor.
Arduino Project 18- Arduino based ultrasonic distance sensor with display
In this tutorial, we will build a digital ultrasonic distance meter. We will use a 16×2 LCD display to view the distance measured. We are using ultrasonic range finder HC-SR04 for this project. The HC-SR04 sensor measures the time taken by the sound waves transmitted after meeting an object that reflects them.
Amarino Experiment- Temperature sensor data and LED controller on Amarino Interface- redirected
This experiment makes the use of ‘Android- Arduino BTCOMM Shield’ and Amarino. If you are not familiar with the shield, visit this page. This experiment is similar to my previous tutorial- Sensor graph and LED controller together. You can also see one more similar experiment- Sensor graph and LED controller using Smart Phone- Arduino Shield. If you…

Turn on an AC lamp using Arduino, 5V relay and motion sensor
This is a simple motion sensor project using Arduino. A 220V AC lamp is connected to a 5V relay and the relay is activated once the motion sensor senses motion and sends a signal to the Arduino. List of materials Arduino Uno (Â Rev 3Â ) Sensor (Â PIRÂ )Â Â HC-SR501 Keyes SRD-05VDC-SL-C Relay Module or any 5V relay module…
2 x 50W Class D Bluetooth Audio Amplifier Board – TSA3118
TSA3118 is a 2x50W audio amplifier board with AudioB plus Bluetooth module. It has perfect class-D architecture (based on TPA3116D2) and each channel has 50W power output. Both channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC 10V-24V power supply. It can be used to drive any 4Ω or 8Ω…
AM receiver from dark sensor
In this case, LDR has been replaced with capacitor C1-0.01uF and resistor R3-1K has been replaced with L1 & VC1. In place of a LED, a Piezo Diaphragm has been kept.
We just need to add inductor, capacitor and a piezo diaphragm to convert a dark detector to an AM radio.
Amarino based Sensor Graph with Custom Bluetooth ID and LED controller
In this project, you can control an LED and see sensor graph simultaneously. For your convenience, I have used a simple light sensor circuit. The resistance of the photo resistor varies with the amount of light falling on it. The amount of light is varied with LED controller and the sensor data variation can be seen on the Sensor Graph.
TINY PROFESSIONAL MICROPHONE PREAMPLIFIER
The board has been design around INA217 low distortion, low noise instrumentation amplifier. The INA217 is ideal for low-level audio signals such as balanced low-impedance microphones. Many industrial, instrumentation, and medical applications also benefit from its low noise and wide bandwidth. Unique distortion cancellation circuitry reduces distortion to extremely low levels, even in high gain….
FM receiver kit and audio amplifier using LM386
This is one of the simplest ways of making an FM receiver. Just get a low cost FM receiver kit, make an audio amplifier using LM386, connect them together and your FM receiver is ready. Most of the commercial FM receiver kits receive the signals within the FM band, usually 88-108 MHz.
How to use DS1307 Real time clock module with Arduino
Most of the microcontrollers are time-agnostic, meaning they are unaware of the time around them, but it doesn’t matter as most experiments do not require it. But, there are several experiments that require the actual time. For example, most of the experiments related to data-logging require time. The following Real time clock (RTC) module can…
