This is a very basic electronic DIY kit for electronics beginners. There are few LEDs in the circuit that can be turned on by sound. The larger the sound intensity the more the LEDs glow. There is a microphone in the circuit which is sensitive enough to pick surrounding sounds.
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,…
The TSRW430 provides a four volt free contact relay outputs with a current rating of up to 30Amp each. The module is powered from a 12VDC supply. The DC input jack is 2.1mm with positive core polarity, DC supplies are required to supply at least 1A at 12VDC. The relays are SPST-NO types. It’s a Wi-Fi…
USB Boarduino is very much similar to DC boarduino. A USB boarduino board has a USB socket in place of DC barrel, that’s all. This product is no longer sold by Adafruit, so, we cannot get the description. However, if you want to order or redesign it, here are the files: Original product link Assembly…
In this post… “Make the lamp respond to light sensor of your phone” About Amarino Lamp (See this article to know about Amarino lamp) This tutorial is related to my previous article. You can use Amarino toolkit application to make a simple dark/light sensor and make the lamp respond to the light present in your room….
LED Flasher is a simple project producing a flashing effect of six LED’s. This project can be used in all areas where you want to draw attention. Hi-glow LED’s providing enough flashing light to attract your attention. Can be used as warning light. SPECIFICATIONS Supply input 12 V @ 35 mA (6 to 15V Dc…
This tutorial is for novices who have never made any Android application or worked with Amarino. If you have never done any experiment with Android and Arduino, please start with this experiment. You don’t need to have previous knowledge of Android for doing this experiment. Simply download any Android serial emulator and upload the Arduino code…

WTV020-SD module is a voice rewritable content type of mass storage voice module, pluggable maximum capacity of 1 GB SD card memory. It can load WAV format files and AD4 formats files. WTV020-SD module  voice chip…
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….
Remote operated musical bell can be made combining the following circuits.
a) Remote tester
b) Basic RC circuit
c) Simple Musical bell
When a remote is pressed, the circuit plays a music.
a) Remote tester
This digital clock kit looks very much similar to this kit, the kit is actually slightly advanced than the previous kit. It has enough functionalities like any other regular clock. It is very accurate. It is an easy to build kit and perfect to start to develop your soldering skills. It uses the chip AT89C2051.
RGB Multicolor Lamp Sensor graph and LED controller: Temperature sensor and LED controller CD4094 control using Android Emulator HOW TO MAKE THIS SHIELD GET ALL THE PROJECTS FOR THIS SHIELD
Introduction In an era characterized by rapid technological advancements and a growing emphasis on collaboration, open source principles have transcended the realm of software and made an indelible mark on hardware development. Open source hardware (OSH) represents a paradigm shift in innovation, fostering a community-driven approach that democratizes access to technology and enables a more…
Here’s a simple experiment with LDR and CD4093. This is just a modification of a previous project “dark sensor using 2 transistors”. In this project, the CD4093 is configured in such a way that whenever you block light falling on LDR, the circuit starts blinking the LED D1. The flasher circuit does not get power…
This sound sensor with Relay driver shield for Arduino Nano can be used to develop sound-activated ON/OFF switch or other projects that require sound senor. LM358 op-amp is used as the amplifier, 1st op-amp amplifies the microphone signal, and 2nd op-amp works as a half-bridge rectifier that converts AC signal into a DC voltage. This DC voltage is connected…
