Simple Electronic Lock Uses Single-Transistor Circuit. May 26, 2003. ... I used a binary code of 0110100111 in my circuit. The switches are implemented in two different ways.
Working of Tilt Sensor Circuit: Initially, the Tilt sensor switch is in closed state which means the output is LOW. Now as per the circuit, the output of the tilt sensor is feed to the base terminal ...
This is a very simple touch light switch circuit that uses the 4011 IC, one transistor and a relay. The C1 capacitor stores the switching state at a certain time and is charged or discharged according ...
And hence, transistor behaves like a close switch and start flowing current between collector and emitter. PNP Transistor Switching Circuit . The concept of PNP transistor as a switch is that, the ...
The circuit in the figure shows a low-cost solution based on a transistor switch (Q1). The transistor is off under normal conditions, when the differential amplifier built around U1 amplifies the ...
The PWM-switch has three terminals, labeled P for passive, A for active, and, C, for the common or inductor terminal.The switch is in the A position for the duty ratio, D, fraction of the cycle period ...
Something like the above is what I'm thinking of. Q1 is a simple PNP transistor acting as a pull-down switch until C1 charges and switches off Q1.
If you ever work with a circuit that controls a decent amount of current, you will often encounter a FET – a Field-Effect Transistor. Whether you want to control a couple of powerful LEDs ...
A switch is described which was designed to meet these conditions. It uses a "normal" transistor in which the functions of the emitter and collector are interchanged periodically by a sinewave ...
