10 Ampere circuit Ampere meter based on ATmega32 128×64 large LCD display it measures 10 amps in 2 channel AC DC used sed1330 Automatically Detect

This project is a 2 channels amp meter. Those channels are completely isolated up to 2000 volts. I’m sure you don’t need isolation like this but it could be very interesting to measure the charge current for 110V AC input or on the output of something like 12V DC. That is, it provides auto detection for AC or DC current. The main part of this project is the current sensor ZMC10 a cool DIP 14, which supports up to 10 A. The current is measured inside by hall effect sensor. I had used a graphic LCD to show very big numbers of the read current and max peek value, DC or AC

RF DC MOTOR SPEED CONTROL AT89S52

System operation: Control circuit and motor control circuits with RF module via serial port 8051 is a one-way communication. Increase or decrease the speed of the speed control circuit of any one of the buttons on the appropriate button is pressed, the cutting program is executed and motor control circuits based on the relevant button to increase the speed or decrease the speed commands are sent. This command area of the control system by evaluating them will increase or decrease the speed of the motor will decide. The engine speed PWM (Pulse Width Modulation) method to set the 8051 program was written. In the form of PWM voltage pulse is sent to the engine. Stay at one of these pulses in the period no matter how long the engine turns so fast. PWM control of the motor speed is generally done in this manner.

8 channel mains dimmer

The heart of the dimmer is a ATTiny2313. the AVR performs three tasks: – It receives new data via the com port, – He receives pulses and the power of positive to negative goes and vice versa, this is called the zero crossing. – He makes 8 pulse-width modulated signal (PWM) with a frequency of 100 Hz. these signals are equal to the zero crossings from the mains.

The PWM signals control 8 optotriacs. These are optocouplers but with a built-in low power triac which can switch. In this project be MOC3021 optocoupler used. You can also add other optotriacs use as long as they have no zero-crossing detection, because working not if you want dim.
