In this tutorial, we will use a servo and a potentiometer to make the servo motor change its position according to the given value given by the potentiometer. Components used in this project: Name Quantity Component U1 1 Arduino Uno R3 Rpot1 1 10 kΩ, Potentiometer M1 1 Servo Arduino Sketch:
Magnetic field sensor project using AD22151 IC from Analog Devices, The AD22151 is linear magnetic field transducer. The sensor output is a voltage proportional to a magnetic field applied perpendicularly to the package top surface. The sensor combines integrated bulk Hall cell technology and instrument technology to minimize temperature related drifts associated with silicon Hall…
This Bluetooth music receiver connects to the RCA input on your home audio system. You can then stream audio from your Bluetooth enabled cell phone or mp3 player to your home audio system.
In this tutorial, we will learn to make a countdown seven segment display project that counts in a sequence from number 9 to 0. To start counting, you need to press the tactile switch. At the end of counting, it flashes the LED and rings the buzzer for a few seconds.
This is a very popular digital click for beginners. It is a DIY Kit. It is now available at BuildCircuit Store. It is based on AT89C2051-24PU. Basic Functions: 1. Hour and minute display & minute and second display 2. Two alarms set up There is a buzzer that works as an alarm. When the clock reaches…
This is yet another digital clock kit built with AT89C2051-24PU chip. We have previously made several digital clock kits for beginners and hobbyists. The kit comes with all the components required.
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.
This works same as the other dark detector circuit. When light is falling on LDR, its low resistance drives transistor Q1-BC547 into conduction. This keeps transistor Q2 cut-off due to low base bias. The D1-LED does not get power as long as ambient light falls on LDR. When the resistance of LDR becomes high in…
TSA1200 has a dedicated remote control, but if the remote control is broken or you want to use your own remote control, this tutorial will teach you how to pair. Note:Â The remote control used must meet the carrier frequency of 38KHz and support the NEC standard. Hardware and Software required: audio amplifier board connection cable…
BuildCircuit has previously published a project on HCSR04 ultrasonic range finder module. You can checkout the article from this link. Now, we have another article on HCSR04. It is as simple as the previous project. HCSR04 ultrasonic range finder module: The HC-SRO4 is an ultrasonic sensor which uses sonar to detect objects at a distance…
In this project, we will build an infrared remote-controlled car so that it can be controlled with any type of infrared remote control. By modifying the design of the robot avoids obstacles we will insert an infrared receiver TSOP4838 or VS1838B or a TSOP 1738 (they only change the pin configuration) instead of the ultrasonic sensor….
This is a simple traffic light project. It is a very easy project to accomplish and serves as a lesson to learn two basic components in electronics, LEDs, and resistors. Components required: D1 D6 2 Red LED D2 D5 2 Yellow LED D3 D4 2 Green LED R1 R2 R3 R4 R5 R6 6 220…
This circuit has been configured in Astable mode. The output pulses are determined by the values of resistors R1, R2 and the timing capacitor C1. The formula for the frequency of pulses is: f= 1.44/[(R1+2R2)*C1].
This project describes how to build an IR remote control extender / repeater to control your electronic appliances from a remote location. An IR detector module receives IR signal from remote control and two IR leds are re-emitting the signal to the appliance. You can place the IR emitting leds close to the device you…
5 LED VU Meter kit is based on LB1409 IC from SANYO, which will indicates the volume level of the audio signal it senses SUPPLY 12V DC @ 50mA PR1 REF SET PR2 AUDIO LEVEL SET SCHEMATIC PARTS PCB DOWNLOADS Audio_VU_Meter.pdf
4 Digit Multiplexed display shield for Arduino Nano with onboard 2 tactile switches and LM35 temperature sensor. This shield helps you to develop many projects that require 4 digit display. For example, a thermometer can be made using on board LM35 sensor. 7 Seven segment multiplexed display is a tiny board and has been designed…
