Arduino Nano Bar-Graph display with universal op-amp shield consists of 10 LEDs and single low voltage general purpose LMV321 op amp including few capacitors and resistors connected to op-amp pins. The op-amp proto area can be configured without any modifications to the board and all that is necessary is to select the correct resistors and…
This is another Arduino Nano shield which can drive a Brushed DC Motor in both directions with PWM signal for speed control and it also includes current trip feature. Project is based on DRV8870 IC which can handle current up to 3.6Amps, The shield also includes an IR sensor and trimmer potentiometer. Trimmer Pot helps to develop speed motor control application,…
This is a 2x8W audio amplifier board with a new AudioB plus Bluetooth module that supports Apt-X. It has perfect class-D architecture (based on TPA3110D2) and every channel has 8W power output. This board can be powered by any DC 8V-16V power supply, it can be used to drive any 4Ω or 8Ω passive speakers.
This is a DC-DC step-up converter based on LM2585-ADJ regulator manufactured by Texas Instruments. This IC was chosen for its simplicity of use, requiring minimal external components and for its ability to control the output voltage by defining the feedback resistors (R1,R2). NPN switching/power transistor is integrated inside the regulator and is able to withstand…
We have been using different online Gerber viewers for checking our Gerber files before sending the PCB designs for manufacturing. We have now started using EasyEDA’s Gerber viewer because it helps us to visualize the PCB that would appear after it is manufactured. The application is pretty straightforward and we can check different files to see the changes on…
The circuit presented here is a LED dimmer with a soft-start function. The board can drive a LED up to 12W and the circuit can manage a load up to 1A continuous with 12Vsupply. The circuit is built using SG3525 PWM IC and the IRFR120 MOSFET, SG3525 generates the PWM, and IRFR120 MOSFET drives the 12W max load. BC847…
I have taken this project from fritzing.org. This project has been released under creative commons license. This project can be useful Arduino beginners for learning 8X8 LED MATRIX. The experiment publisher has made a simple snake game. I have not tested this project, but I am sure that it should work on your breadboard also.
I have written several posts similar to this one before. This experiment is again about a dark sensor based on LDR or photoresistor. There are a few components and basic soldering experience should be enough to build this up. It is a good and easy kit for electronics beginners.
There are hundreds of electronics projects published on buildcircuit.com. This time we have selected few projects that should be easier for beginners to start with. Complex and difficult projects just frustrate the beginners. The best thing about the listed projects is that all come with good assembly images and most of the projects can be…
This is yet another audio amplifier project. It is based on TDA2282 chip. The TDA2822M is a monolithic integrated circuit in 8 lead Minidip package. It is intended for use as dual audio power amplifier in portable cassette players and radios. Datasheet of TDA2282 You can see all the assembly images below. You can see…
The 4 channel RF receiver and transmitter can be used with or without an Arduino. You can connect relays to the receiver outputs to control it wirelessly.
In this tutorial, we will learn to make a buzzer sound like an ambulance siren and at the same time we will flash an LED. We will learn to change the frequency of the sound to make a two-tone sound. If you want you can insert a potentiometer to increase or decrease the volume.
TSA8635 is a compact size and easy to use Bluetooth audio receiver. This Bluetooth music receiver connects to the Line-In or Aux input on your home audio system. You can also stream audio from your Bluetooth enabled cell phone or mp3 player to your home audio system. Note: We can provide OEM/ODM service for…
CTR-30 flash Christmas tree kit consists of three circuit boards, allows 36 LED flash alternately, showing a Christmas tree in the space of a three-dimensional profile. It appears excellent at night.
About Amarino Shield Amarino shield can be used for doing several experiments with Amarino and Android serial emulators. For example, you can operate a multicolor lamp, sensor graph, light sensor, etc. The shield is just a modification of previous shield designed and published by Sagar Sapkota (Buildcircuit.com). Amarino shield 3.0 has added one more header space…
This project includes 10 LEDs of 1W each, and provides high intensity lighting that can be used in various applications. The board is made in Arduino shield form and can be used with Arduino Uno or Mega. Each LED can be controlled individually connected to digital pins D2-D11 of Arduino. Circuit requires 9-12V supply, it…
