LED chaser with only one IC555

This circuit is a simple LED chaser, (Bike Turning Signal Circuit) used IC 555 and 5 transistors.
Here we used IC 555 as astable multivibrator to running the transistors.
Flashing speed depend on both capacitors.
1K resistors used for each LED as protection.
The circuit run with 12v and draw 40mA current when all LEDs be turn ON.

Parts list:
IC555
LEDs(5pcs)
Transistor S9013(5pcs)
Diode 1N4148
Capacitor 470uF
Capacitor 100uF
Resistor 1K (6pcs)
Resistor 4.7K (2pcs)
Resistor 10K (2pcs)
Resistor 680 ohm

A2XWY; A2XFY Cables meaning; XLPE cables advantages over PVC cables

Technical Specification of Aluminum Cables in terms of codes So many times you have seen coding while specifying cables technical such as A2XWY now what does this means. Now there is nomenclature for the same which is used while describing the same. Where A -  Aluminium 2X- XLPE Insulation W – Steel round wire armour F- Steel Strip Armour WW- Double Steel round Armour FF- Double Steel Strip Armour Y- PVC outer Sheath Wa- Non Magnetic round wire Armour Fa- Non Magnetic Strip Armour AW- Aluminum Wire Armour Now As per A2XWY – This describes that it is Aluminum cable, XLPE insulated, With Steel round wire armour and having PVC outer Sheath. This coding is as per IS 7098(Part1):1988. You have also seen that there is coding for copper so there is no coding required in case of copper cables. XLPE cables advantages over PVC cables/ Thermoplastic cables:- 1.       XLPE cables have higher Power rating about 1.2 times PVC cables 2.       XLP...

Digital Multimeter working principle; DMM working

Image
Digital multimeters are most widely used in every industry as it used for measurement of Voltage, Current, Resistance, Capacitance and various other parameters. DMMs have been available for very several years. Yet it is still challenging to locate advice about how a digital multimeter works. The operation of a digital multimeter is comparatively uncomplicated, although there are obviously differences in how digital mulimeters work if they're from different makers.Despite this, there are several similarities and some general principles of how digital multimeters work. Fundamentals of how a DMM functions The key process occurring within a digital multimeter for any measurement is that of voltage measurement. All other measurements are derived from this basic measurement. So the best technique for understanding how a digital multimeter functions is in understanding this procedure. There are many kinds to digital converter, ADC. Nonetheless the one that is most widely used DMMs in di...

Wireless voltmeter using Arduino and RF 433MHz receiver and transmitter

Image
In this project i showed you how to make a wireless voltmeter using arduino and RF 433MHz receiver and transmitter. You can use this code and concept for many other projects, any project which used sensor with analog voltage output to sense temperature, gas leakage or light , etc. For example you can put a LM35 temperature sensor rather than potantiometer, you just have to putting its formula which convert LM35 output pin voltage to exact temperature. You also can make a wireless AC or DC power meter by doing some change in code and hardware (using hall effect current sensor and single phase voltage sensor). This type of RF module has distance range up to 200 meters according to datasheet but when i bought this RF module from Aliexpress its distance rang was very low, but i set its adjustable RF coil very carefully and i get very higher distance rang.(Don't play with RF coil if your module works good), You also have to use a 6 inch antenna to increase distance range to max as possi...
