In this article, we are going to describe how you can use the “fully assembled clap_switch” to light up 100-240V appliances. When we say 100-240V appliance used with a clap switch, it is usually a bulb/lamp/CFL(Compact Fluorescent Lamp) tube. This article is for absolute beginners, so, we will try to explain all the small details.
This is yet another MicroSD card breakout board for Arduino. Previously, we had released a similar MicroSD breakout board on our website. This module is bit cheaper than the previous one, that’s the only difference. As we all know most of the microcontrollers have limited built-in storage. For example, Arduino UNO (Atmega328) has 1Kbytes of…
Here is a simple and a low cost Lithium Battery charging breakout board. This article is about the charger breakout board based on TP4056. It uses a Micro USB for connecting the breakout board to any computer or ‘USB wall adapter’. It works with linear charging method. It offers 1000mA charge current by default but…
The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only…
Description: Here’s a simple DIY clap switch circuit. The circuit is mainly composed of an audio frequency and a bistable trigger circuit. Q1 and Q2 together form an amplifier circuit. MK1 (electret microphone) accepts Clap/Audio signal and that enters to transistor Q1 through the coupling capacitor C1 and enters to Q2 base through collector directly after getting…
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….

The LM317 is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5 A over an output-voltage range of 1.25 V to 37 V. It is exceptionally easy to use and requires only two external resistors to set the output voltage. Furthermore, both line and load regulation are better than standard fixed regulators.
