This is a 2 x 50W audio amplifier board with AudioB plus Bluetooth module. It has a perfect class-D architecture (based on TPA3116D2) and every 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…
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 tutorials on RGB multicolor lamp using Amarino. and RGB multicolor lamp with custom Bluetooth ID on Amarino Interface. If you have never worked with Amarino, I strongly…
How many times have we wished to have a robot that goes around the house avoiding obstacles? Creating this project with Arduino Uno, an HC-SR04 module and two wheels will take us to be a child. The robot is able to avoid obstacles, thanks to the ultrasonic range finder sensor that senses obstacle coming on…
TSA1020 is a digital stereo Bluetooth/Single-ended audio volume controller board. It has an RCA audio input/output ports and a BVC port (only for some Bluetooth amplifier boards). You can use it to control audio volume any normal amplifier board. The audio out signal will increase/decrease when the user rotates the knob, Bluetooth audio volume control port will also…
TSA1010 is a digital stereo Bluetooth/Single-ended audio volume controller board. It has two 3.5mm audio jack and a BVC port. You can use it to control the audio volume of any normal amplifier board. The audio out signal will increase/decrease when a user rotates the knob and Bluetooth audio volume control port will also output an…
TSA1110 is a smartphone Bluetooth audio volume controller. It has integrated a digital potentiometer and a powerful Bluetooth and its control distance is up to 30m (outdoor). After it gets connected to your audio amplifier, you can use an Android or iPhone App to control the audio volume from the smartphone. There are 3 ports for…
8 Digit serial numerical display shield for Arduino has been designed for various applications like digital clock, stop watch, score display, temperature meter, frequency counter, digital meters etc. The circuit uses popular MAX7219 IC and two common cathode 0.5inch red seven segment displays. The MAX7219 is a compact, serial input/output common-cathode display drivers that interface…
Enable/Change The BT Pair number All of our Bluetooth audio amplifier boards and Bluetooth audio receiver boards use AudioB plus module as the core bluetooth receiver module. The default bluetooth name is “BT SPEAKER”. Maybe you want change it to a special name or add a password to this module. We just updated the AudioB plus design…
Arduino Code: Download Edit the code for getting the output on serial monitor. I recommend you to see the listed posts before you start this project.
In this tutorial, we will turn on and off the LEDs sequentially, such as Christmas tree lights.
This is yet another sound activated LEDs circuit. I have previously published a similar project.
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…
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 fully assembled sound/clap operated switch can be used for turning on your 100-240V AC light bulbs. Usually, we use a clap switch to operate a lamp and it can easily do that for you. The kit responses to clap up to distance of 5 meters, but, the further you go, the louder the clap…
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:
WTV020SD-16P music module is one of the hot topics in current days. WTV020-SD module can be used in automotive electronics (anti-theft alarm, parking sensor, GPS navigation systems, electronic dog, central locking), smart home system, home burglar alarm, medical instruments, the human voice prompts, music player, home appliances (cooker , rice cookers, microwave ovens), entertainment devices…
This is a compact size Bluetooth 5.0 audio transmitter. Maybe your music player (TV, Computer, DVD, Radio etc.) does not have Bluetooth function and you don’t want to use a cable to connect with our amplifier board. You can use this little thing to let your audio player connect with your Bluetooth amplifier board wirelessly.
