Remote tester circuit also resembles the logic of a “dark sensor (using BC557)”. LDR has been replaced with IR sensor TSOP 1738. The circuit works as a remote tester. Pressing a remote control switch near the IR sensor, switches on the LED D2.
This tutorial gives extremely simple easy for changing the baud rate of your BlueSMiRF Gold/silver bluetooth module. In this article, I have presented the baud rate changing steps done on Windows 7.
Description: This is a simple object counter circuit that counts from 0 to 9. You can make this project using four different modules listed below: Infrared remote tester RC module Counter module Astable module
This do-it-yourself(DIY) sound/clap operated switch can be used for switching your 100-240V AC electrical appliances. 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 10 meters, but, the further you go, the louder the clap should be.
VT-100 terminal emulator is a program for communicating with any serial device using a Bluetooth serial adapter. The RFCOMM/SPP protocol emulates serial communications over Bluetooth. You need a Bluetooth serial adapter.
Current sensor amplifier and over current switch project is based on ACS714-30A current sensor and LM358 Op-amp, ½ of LM358 op-amp used as an amplifier for low voltage and 2nd 1/2 LM358 op-amp used as comparator which provides over current TTL output, trimmer potentiometer provided to set the over current limit. ACS714 sensor measures the current…
This project is similar to the following projects: 1. ON and OFF LED using infrared sensor 2. PWM experiment using infrared sensor For this particular and the above listed experiments, you need this library: arcfn.com/files/IRremote.zip See the following image to know how to fix the infrared sensor on the breakout board. http://arcfn.com/files/IRremote.zip#sthash.wIx2Q2Mr.dpuf http://arcfn.com/files/IRremote.zip#sthash.wIx2Q2Mr.dpuf http://arcfn.com/files/IRremote.zip#sthash.wIx2Q2Mr.dpuf Datasheet…
This tiny board designed to drive bidirectional DC brushed motor of large current. DC supply is up to 50V DC. A3941 gate driver IC and 4X N Channel Mosfet IRLR024 used as H-Bridge. The project can handle a load up to 10Amps. Screw terminals provided to connect load and load supply,…
On this post, you will see how Amarino shield can be used for Android- Arduino experiments. It shows some basic experiments with android serial emulator and Amarino toolkit. You can get the original Amarino source codes and installable files also. Just install the application on your Android phone and experiment with the kit. This page…
This is a Type K Thermocouple Sensor Amplifier Arduino Shield that enables an Arduino board to acquire temperatures from a thermocouple of type K. The shield works with a single supply and takes 5V DC from the Arduino board, the output of the circuit is 0 to 4V DC for 0-degree centigrade to 400C. The output of the amplifier…
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…
4 Digit Multiplexed display shield for Arduino Nano with onboard 2 tactile switches and LM35 temperature sensor. This shield helps you to develop many projects that require 4 digit display. For example, a thermometer can be made using on board LM35 sensor. 7 Seven segment multiplexed display is a tiny board and has been designed…
The board has been design around INA217 low distortion, low noise instrumentation amplifier. The INA217 is ideal for low-level audio signals such as balanced low-impedance microphones. Many industrial, instrumentation, and medical applications also benefit from its low noise and wide bandwidth. Unique distortion cancellation circuitry reduces distortion to extremely low levels, even in high gain….
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.
