Simple Stepped Volume Control

Many audio systems consist of separate units, and due to economic reasons, only the amplifier is equipped with a remote control receiver module. In audio system designs where components are split into separate units, it is common for only the...

The wireless remote control transmitter circuit consists of control buttons S1 to S16, resistors R1 to R3, a capacitor C1, a regulator diode VS, a crystal oscillator BC1, and DTMF encoder integrated circuits IC1 and IC2. The circuit components...

This is an infrared (IR) remote control designed for Nikon cameras, specifically compatible with the Nikon ML-L3 remote control. The supported camera models include D40, D40X, D50, D60, D70, D70s, D80, Coolpix 8400, and 8800. The circuit design is...

This circuit is designed for ease of tuning. When the pulse voltage reaches 6V, all transistors operate as open switches, eliminating the risk of battery shorts. The pulse voltage source V5 can be substituted with a 555 astable circuit....

The function is designed to automatically control the speed of a fan based on the temperature. Components include a BT136 Triac, capacitor, resistor, relay, and fan motor. The circuit employs a temperature sensing mechanism to monitor ambient temperature levels. A...
