A single-transistor FM transmitter DIY kit is a simple electronic circuit that allows you to broadcast an audio signal wirelessly using frequency modulation (FM). Such kits are popular among electronics enthusiasts and hobbyists due to their simplicity and educational value. Let’s break down the working of a typical single-transistor FM transmitter: Components: Transistor: The heart…
In this project, we will build an infrared remote-controlled car so that it can be controlled with any type of infrared remote control. By modifying the design of the robot avoids obstacles we will insert an infrared receiver TSOP4838 or VS1838B or a TSOP 1738 (they only change the pin configuration) instead of the ultrasonic sensor….
In this tutorial, we will use the digitalRead function and learn how to read a digital pin. In our case, the digital sensor that will be read will be a common button/reset tactile switch that when pressed will turn on the LED. Components required: Name Quantity Component U1 1 Arduino Uno R3 D1 1 Green…
