Description:Â This wireless transmitter and receiver pair operate at 315Mhz. They can easily fit into a breadboard and work well with microcontrollers to create a very simple wireless data link. Since these are only transmitters, they will only work communicating data one-way, you would need two pairs (of different frequencies) to act as a transmitter/receiver pair….
SEE ALL THE PHOTOS ON FLICKR This post shows you how to build the Amarino evaluation shield. When you buy the shield package, you will get the following components. Fully assembled kit is now available on buildcircuit.net. The PCB: PCB clearly shows the pin and component names, so, it should help you to get idea of…
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 Sensor Graph basic experiment and Sensor graph and LED controller together. If you have never worked with Amarino, I strongly recommend you to visit Amarino page…
This is a basic electronic kit for beginners. The kit has few SMD component and few through-hole components. Because it has SMD components, it is recommended to use a temperature-controlled soldering iron to solder the CD4060 chip. You need to set the temperature to 300°C, otherwise, you may burn the chip and the kit will…
Description: You can make an up counter using a counter module and a multivibrator module. First make a simple multivibrator, then make a counter and then combine them.Â
TSA7500 2x100W + 220W 2.1 channels audio amplifier board comes with AudioB pro Bluetooth module that supports Apt-X. 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.
Before making an Arduino programmer on breadboard using FT232RL, you need to know about arduino, breadboard and USB to serial FT232RL break out board. If you are an electronic novice, I recommend you to visit this page to get ideas on building simple electronic projects on breadboard.
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].
You can build simple LED chaser circuits using CD4017 and NE555 timer. There are hundreds of projects in the internet for making such simple LED chaser circuits.
The TSRU430 provides four volt free contact relay outputs with a current rating of up to 30Amp each. The module is powered with a 12 VDC 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 USB…
If you have come to this page from a search engine, please check this page first, you will eventually come to this page again. About Cosmarino The assembly process of the Cosmarino kit is very straight forward. You just need to follow the silkscreen labels to get the idea of assembly. A basic knowledge in…
555 timer configured in monostable mode is a simple automatic dark sensor circuit that gives output when light falling on LDR is blocked.
Change The BT module audio gains All of our Bluetooth audio amplifier boards and Bluetooth audio receiver boards use AudioB plus module as the core bluetooth receiver module. If you have to use a mismatch speakers or power supply in your system(size limit or other reasons). You may want limit the maximum output audio gains…
This is a Wi-Fi Relay remote control kit that includes: 1 x 2 Channel USB/Wireless Relay Module 1 x Wi-FiBee WiFi module 1 x Xbee USB adapter 1 x Mini USB cable You can easily control this relay module by your computer using Wi-Fi. Note: Please remove the Wi-Fi module when you use USB connection. USB/Wireless Relay module…
The Project works as electronic toggle switch. DESCRIPTION The circuit is based on CMOSÂ CD4013Â Flip Flop IC, The circuit has two stable states, ON and OFF. Once it is ON, it remains ON till you press the switch again. A short button press of a tactile switch SW1 latches the circuit ON and another toggles it…
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 is a Bluetooth audio receiver which supports TWS function. This Bluetooth audio receiver connects to the Line-In or Aux input in your home audio system.
