Assembling the infrared music transmitter and receiver kit is pretty straightforward. You can simply follow the silkscreen indicator and solder the components on its right spot.
TSIR04 is a USB relay with optically isolated inputs and OLED display and temperature sensor port. It allows computer control switching of external devices by using the USB port of your computer. The communication medium also can be changed easily. Replace the USBBee module with a WiFiBee, it becomes a WIFI relay. It will be a Bluetooth relay when…
This is a MAX7456 OSD ( On Screen Display) shield for Arduino. The user can easily interrupt and overlay text and/or graphics onto a video signal (PAL or NTSC). It’s just about “plug-and-play” with an Arduino board. Plug this shield over Arduino main board and upload the given test sketch. Plug in your video signal to…
Most of the microcontrollers have limited built-in storage. For example, Arduino UNO (Atmega328)has 1Kbytes of EEPROM storage and it might not be enough for all projects. If your project has any graphics, video, audio and data logging feature, you need a removal storage in it.
The pressure sensor amplifier built using LM358 op-amp and MPXM2051GS pressure sensor from NXP semiconductor. The circuit provides 4V output for full scale pressure input 0-7.5PSI. One op-amp is used as amplifier and 2nd op-amp is used as comparator to provide an output at set value that can be used as over pressure switch to control…
This project is a microphone pre-amplifier based on LM358. DESCRIPTION This is easy to construct microphone pre-amplifier project using compact electret condenser microphone. The pre-amplifier is important building block of many audio communication systems. Circuit has been built around Op-Amp LM358. Power supply : 5 to 12 VDC @ 10 mA Output: Gain Approx. 100 On-Board…
TSA7500 2x100W + 220W 2.1 channels audio amplifier board comes with AudioB pro Bluetooth module. It has a perfect class-D architecture (based on TPA3221) and 2 channels have 100W power outputs and another one channel has 200W power output.
This is basically a module similar to FTDI/FT232RLbasic breakout board. CH340 is a series of USB bus adapters, that provides serial, parallel or IrDA interfaces over the USB bus (note: CH340G supports serial interface only). The CH340G integrate circuit provides common MODEM signals to allow adding a UART to a computer or converting existing UART devices to USB…
We are now selling the BLUE COLORED DIY Arduino kit This post shows you how to assemble the DIY Arduino board. The assembly process is straight forward. It can be easily assembled if you follow the silkscreen indicators(labels) and have beginning experience with a soldering iron. You will need to read the resistor bands or use…
Designed by: Sagar Sapkota (Contact) (IT IS NOT A COMMERCIAL PRODUCT- PLEASE DON’T ASK FOR ITS DESIGN) This is my Master’s degree thesis project. I did this project at the University of Turku, Finland. I completed this project in March 2012. The project was selected for an international conference organized in Japan. Features of the…
The DRV101 is a low-side power switch employing a pulse-width modulated (PWM) output. Its rugged design is optimized for driving electromechanical devices such as valves, solenoids, relays, actuators, and positioners. The DRV101 module is also ideal for driving thermal devices such as heaters and lamps. PWM operation conserves power and reduces heat rise, resulting in…
I recently found a video explaining the open source hardware. It’s good to see an association for the open source hardware community. You can be a member, support the association and keep yourself updated with the technologies coming up in the open source world. Link: http://www.oshwa.org//a
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…
An automatic dark sensor can be made using a PNP transistor(BC557).
A relay is an electrically operated switch. Current flowing through the coil of the relay creates a magnetic field which attracts a lever and changes the switch contacts. The coil current can be on or off so relays have two switch positions and they are double throw (changeover) switches. The relay’s switch connections are usually labeled COM(POLE), NC…
