A switch is the most essential part of any circuit. Different circuits ... ground pin to the 5V and ground of the Arduino. Connect the SIG or OUT pin of this module to the pin8 of the Arduino. Connect ...

Transistors are inevitable parts of Electronic circuits. The success of a circuit design lies in the selection of proper transistor type and calculation of voltage and current flowing through it. A ...

Many of us who have worked with Analog circuits ... using transistor. The circuit used in this tutorial will be able to able to deliver a constant current of 100mA to your load but you can modify it ...

We all know, at least intellectually, that our computers are all built with lots of tiny transistors ... CPU to get up and running. The design does rely on an Arduino for memory to simplify ...

The design looks ... to the base of the transistor. This positive feedback help in improving the effective value of the base resistance. This increment in the base resistance also determined by the ...

One of the most popular Elektor projects in 2015 was Burkhard Kainka's medium-wave AM transmitter design. Let’s revisit ... Refer to the AM transmitter circuit. All components on the left-hand side ...

The following automatic battery-charger design is created with a circuit that could qualify as the simplest window comparator ever built around a single transistor (see the figure). It starts ...

DO NOT connect in any ways the main power supply that drive the LOAD to the arduino and transistor circuitry! You can use this code example to introduce a delay in your circuit. The variable “stayON” ...

Here’s how Kainka's design works: A coil and capacitor form a series resonant circuit, energized by the transistor’s collector. As the transistor alternates between conducting and blocking, the coil ...

Described here is a simple circuit of an Arduino-based shadow alarm ... The signal from LDR1 is fed to digital input pin 2 of Arduino through transistor T1 (BC547). The input to the Arduino is ...
