The range of a Wi-Fi signal can be influenced by several factors, which can impact its coverage and strength. Understanding these factors can help you optimize your Wi-Fi network for better performance. Here are the key factors that affect Wi-Fi transmission range: Frequency Band: Wi-Fi operates in different frequency bands, such as 2.4 GHz and…

One of the main objectives of LDR Engineering projects is to make students capable of developing their own logic for making devices. Here is an example that tells how LDR Engineering helps in developing ideas.
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…
Bluetooth technology has become an integral part of our wireless communication landscape, enabling a wide range of devices to connect and exchange data. However, the transmission range of Bluetooth connections can vary based on several factors. Here are some key factors that affect Bluetooth transmission range: Bluetooth Version: Different Bluetooth versions offer varying ranges. The…
TSA7510 is 2x100W audio amplifier board with AudioB plus Bluetooth module. It has a perfect class-D architecture (based on TPA3221) and each channel has 100W power output. Both channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC 12V-30V power supply. It can be used to drive any 2Ω,4Ω or 8Ω…
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…
It is a simple LDR based ‘Happy Birthday To You’ music player. When you block the light falling on the LDR, the kit stops playing the music. There are 18 flashing LEDs and the buzzer plays “Happy Birthday to You” song. A photoresistor or LDR works here as the photosensitive element. The jumpers are used…
In this case, LDR has been replaced with capacitor C1-0.01uF and resistor R3-1K has been replaced with L1 & VC1. In place of a LED, a Piezo Diaphragm has been kept.
We just need to add inductor, capacitor and a piezo diaphragm to convert a dark detector to an AM radio.
Check out similar robotics chassis at Buildcircuit store Sparkfun.com has recently released a simple, easy and useful robot platform for robotics amateurs. It is called “Magician Chassis”. You can use the chassis for different kinds of robots, for example, line sensing, obstacle detecting and smart phone controlled robots. I have recently published an easy project…
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 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.
Strobe provides regular flashes of light. Usually Strobes are designed using Xenon Tubes. Here is LED based simple solution that can be used as strobe for entertainment and events and also as warning signals. Project is based on PIC16F1825 micro-controller with two digit frequency display. Project provides TTL output signal, frequency 1Hz-25Hz, Tact switches provided…

In this tutorial, we will see how to use Arduino with a stepper motor and a joystick. To control the stepper motor we will use the driver control board that can drive up to about 750mA per port, so it is perfect to be used with this motor.
TSA1110 is a smartphone Bluetooth audio volume controller. It has integrated a digital potentiometer and a powerful Bluetooth and its control distance is up to 30m (outdoor). After it gets connected to your audio amplifier, you can use an Android or iPhone App to control the audio volume from the smartphone. There are 3 ports for…
