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…
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…
TSA7510B is a 2x100W audio amplifier board with a new AudioB plus Bluetooth module that supports Apt-X. It has perfect class-D architecture(Based on TPA3221) and each channel has 100W power output. Both of channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC12V-30V power supply. It can be used to drive…
This Mini Audio Power Amplifier is capable of delivering 1W of continuous RMS Output Power into 8 ohms load @ 5V. The Amplifier is built using TS4871 IC from ST. This Audio Amplifier is exhibiting 0.1% distortion level (THD) from a 5V supply for a Pout = 250mW RMS. An external standby mode control reduces the supply…
In this tutorial, we will build a thermostat to independently activate and deactivate any domestic device depending on the temperature. We will be able to display the temperature and the activation status of the device connected to the relay on the 16×2 LCD display. Moreover, on the sketch we can modify the temperature, detected by…
TSA6175 is a Bluetooth 5 multipoint audio receiver. You can have many TSA6175s paired and work together. You can also let it work like a normal Bluetooth audio receiver. This Bluetooth music receiver connects to the line-In or Aux input on your home audio system. You can then stream audio from your Bluetooth enabled cell…
This is a TSTR04 USB relay board which has an OLED display and 4 temperature sensor ports. In “Normal” mode, you can easily control this relay board by your computer or smartphone via Wi-Fi. In “Auto” mode, you can set a threshold value, to let the relay turn ON/OFF based on the temperature. So, you can use it…
Dark Sensitive switch project based on single BC547 transistor, Relay operates when light that falls on the LDR, goes below a set point. It’s very simple and low cost dark sensitive switch required few components. FEATURES Input : 12 VDC @ 55 mA Relay output : NC – C – NO Onboard preset to set…
This is yet another heart-shaped multicolor LED flasher DIY kit. The soldering process is pretty straight forward. The silkscreen label should guide you through soldering. It takes around half an hour to build the kit and basic soldering skill is enough to build it.
TSA3117B is designed for mass production and DIY users. Bluetooth/LINE IN select switch and audio input port are designed as JST connectors. So, users can install this amplifier board in a box and connect an external switch and RCA/Mono plug to make their own audio amplifier.
Description: Here’s a simple do-it-yourself (DIY) remote operated switch. You can use this simple kit to switch ON/OFF any appliances working on 220V AC. This DIY kit has been designed basically as a learning kit rather than as a household device. With this kit, you may learn about relay and infrared sensor. It can used for fun at home for switching…
