  • Figure:2 TCCR2 (Timer Counter Control Register)

    DC Motor Speed Control Circuit using Microcontroller

    Posted Dec 28, 2014 By Sudheer Gupta
    In many applications, it is important to control the speed of DC motor where precision and protection are essence. Here we will use a technique called PWM (pulse width modulation) to control the speed of DC motor. We can achieve speed control of DC motor using mechanical or electrical techniques but they require large size hardware to implement but Microcontroller based system provides easy way…

  • Figure:4 Timer Alarm Circuit 1

    Timer Alarm Circuit

    Posted Dec 20, 2014 By Credible Sport
    This is a basic application of 555 timer. It is used as part of the timing circuit in which it varies time interval with respect to the value of resistance given. It is useful for simple application where fixed timing is needed. The complete design is provided at link-> http://schematics.com/project/timer-alarm-circuit-14342/

  • Figure:6 Solar Battery Charger Circuit

    Solar Battery Charger

    Posted Dec 14, 2014 By Sudheer Gupta
    This is a simple solar battery charger circuit designed using LM317 voltage regulator and is used to charge Lead-Acid or Ni-Cd batteries using solar energy. This solar charger has current and voltage regulation and also has over voltage cut off facilities. Here the solar panel produces 12 V DC. The charging current passes to LM317 voltage regulator through the diode D1. The output voltage and…

  • Figure:10 Circuit Diagram of Light Activated Switch

    Light Activated Switch Using LDR

    Posted Nov 30, 2014 By Sudheer Gupta
    The main principle of this circuit is to switch ON the light when the LDR is illuminated. The light dependent resistor will have high resistance in darkness and low resistance in the light. The comparator used here has LDR connected to its inverting terminal and potentiometer connected to its non-inverting pin. When the light falls on the Light Dependent Resistor, the comparator compares the…
