Touch Motor Control by SCR and Schmitt Trigger

This circuit designs for control DC Motor 12Volt. By use the touch once Motor as a result turn go to once. When use a finger touches the metal makes Schmitt Trigger Circuit take a signal from Oscillator Circuit and make a signal goes out Trig SCR Bias Current the DC Motor 12V then turn follow want. For power supply type of DC Motor this must be AC 12Volt Only. because of make SCR not bias during negative current there. And this circuit works not heavy DC motor, turn ? do not turn ? Then don’t have to stick heat sink give SCR1 for DC motor you will may use motor at use in an automobile all right. Request enjoy please, sir.

RF Dual DC Motor Controller
The transmitter circuit consists of WZ-X01 RF module, Holtek HT-640 encoder and 8-bit A/D converter. U1 ADC0804 converts the analog voltage to digital data; U2 encodes that data (D0~D6) along with D6, D7 and transmitting through the RF transmitter module. The potentiometer VR1 varies the voltage ...
DC Servo Motor Driver by PIC16C71
A Servo Motor is a small device that has an output shaft which can be positioned to specific angular positions by sending the servo a Pulse Coded Modulation signal. As the coded signal changes, the angular position of the shaft changes. DC servo motors are used in radio controlled airplanes, ...
Slow Servo
Realistic flap and landing gear actuation. This circuit slows the speed of a conventional proportional servo. It regulates the time required for full servo rotation from 1 to 10 seconds without any reduction in the servo's torque, and every servo position is possible (proportional). Vi ...
The transistor lat
This circuit, it works similar to a SCR.When the trigger input is high, The transistor Q2 and Q1 will work,therefore a current flow to the base pin of Q2,it has voltage 0.7 volts at resistor R1. When cutting the activation voltage, the transistors can continue to perform, because the base c ...
Touch Switch By IC 4001 & 4020
Circuit Touch Switch By IC CD4001, CD4020 This be touch switch be simple again the circuit. It use integrated digital circuit is important equipment, and use volt power supply low just 9V. By use single metal, it works in the character turn ON and turn OFF. By when touch for the first tim ...
