There is an in-built equalizer in Tinysine Bluetooth 5.0 module. If you have the CSR USB-SPI programmer, you can change the equalizer settings by yourself. TSA6175 module uses the CSR8675 Bluetooth chip. It needs a new version software to change the EQ settings. This tutorial will teach you how to set it. Hardware and Software required: Tag-Connect…
CTR-30 flash Christmas tree kit consists of three circuit boards, allows 36 LED flash alternately, showing a Christmas tree in the space of a three-dimensional profile. It appears excellent at night.
This is yet another audio LED spectrum DIY kit. Connect the kit to any audio source and see the lights patterns changing according to the audio signal.
This 555 timer circuit below toggles the LED when a button is pressed. Pins 2 and 6, the threshold and trigger inputs, are held at 1/2 the supply voltage by the two 10K resistors.
CRYSTAL SET The simplest radio receiver, known as a Crystal Set, consists of nothing more than a coil, tuning capacitor, diode detector, and a pair of earphones. A typical circuit diagram for a Crystal Set Radio is given below where inductor or coil L1 is tuned by variable capacitor VC1 to the transmitter frequency. Diode D1 demodulates the signal, which is…
Arduino Nano Bar-Graph display with universal op-amp shield consists of 10 LEDs and single low voltage general purpose LMV321 op amp including few capacitors and resistors connected to op-amp pins. The op-amp proto area can be configured without any modifications to the board and all that is necessary is to select the correct resistors and…
This is the first experiment for Amarino shield. If you do not know anything about Amarino toolkit or this shield please click on the following links: About Amarino toolkit About Amarino shield You can get a list of other experiments at the end of this post. This experiment has been derived from HEF4794_- Arduino_ Experiment….
This amplifier does not have Bluetooth. This is TSA7600 2x100W + 220W audio amplifier board. It has perfect class-D architecture (based on TPA3221) and 2 channels have 100W power output and another one channel has 200W power output. All the channels are capable of outputting nominal power simultaneously and continuously. This board can be powered…

Description: In this clap switch we use three different modules given below. It is necessary to make these three modules in order to make a clap switch. a. Dark sensor using 2 transistors. b. Monostable mode of 555 timer. c. Toggle switch using 555 timer.Â
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…
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.Â
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 phone or mp3 player to your home audio system. It comes with a new AudioB plus Bluetooth module that supports Apt-X. Note：TSA6013 can auto-detect the Aux in/Line in Audio input. Bluetooth…
This tutorial is related to my DIY remote operated switch kit. If you have come to this page from a search engine, please visit this page first. Before trying this experiment, I strongly recommend you to learn about  relays. It can be dangerous and lead to serious accident if you don’t know how to connect…
