The project described here is a compact stereo volume and balance control with a rotary encoder. It provides 32 log potentiometer steps with buffered wiper output. The project can easily replace mechanical potentiometer. 5 LEDs indicate the volume level or balance settings , depending on the status of the mode indicator D1 LED. The MAX5440Â includes…
Here’s a simple latch-up circuit using 555 timer and opto-coupler MCT2E. You can also use PC817 in place of MCT2E. The NE555 timer is configured in astable mode.The components are selected in such a way that the frequency output of the astable circuit lies within the audio range. Opto-coupler, MCT2E is is used for latching…
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…
USB powered mini speaker amplifier is conveniently powered by USB and it is simple to set up. USB powered speakers are convenient for listening to your media while at home or on the go. Conventional computer speakers that require an electrical outlet to work can be prohibitive because they force you to be close to…
The TSRW430 provides a four volt free contact relay outputs with a current rating of up to 30Amp each. The module is powered from a 12VDC supply. The DC input jack is 2.1mm with positive core polarity, DC supplies are required to supply at least 1A at 12VDC. The relays are SPST-NO types. It’s a Wi-Fi…
Discover a 64 × 48 cm digital cricket scoreboard with a separate Target display and automatically rotating Runs, Wickets and Overs.
TSA7499B is designed for audio amplifier manufacturing factories or DIY electronics makers/users. Bluetooth/LINE IN select switch and audio input ports are designed with JST connectors. That allows users to install this amplifier board in a box and connect an external switch and RCA/3.5mm audio jack plug to make their own audio amplifier.
A dark sensor can be converted to a simple FM transmitter using the following components. This FM transmitter is very sensitive and it has transmitting range of 30 meters.
In this tutorial, we will learn how to use a servo motor. A Servo is a motor capable of making maximum rotations of 270° and is widely used in robotics and modeling. It requires a library (<Servo.h>) that is already installed on the Arduino IDE software. In this tutorial, we will vary the position of…
Description: This is a basic breakout board for the FTDI FT232RL USB to serial IC. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 5V Arduino boards. It can also be used for general serial applications. The major difference with this board is that it brings out the…
