Basic electronics projects

Small electronic projects

Lets have look at the project, I hope you like it. In addition, there needs to be a conductive path that provides a route for the electricity to flow. We suggest you go through all the comments before practically testing any of these circuits which will save you a lot of troubleshooting time. All circuits need to have three basic elements. A capacitor is like a rechargeable battery and can be charged and then discharged. Wire Cutter Wire cutters are essential for stripping stranded and solid copper wire. Decade counter IC has ten outputs which go on high in sequence when pulses are applied at the clock input. The longer leg of the LED is the positive anode side. Mosquito repellent Circuit Some of the mosquito repellents available in the market use a toxic liquid to generate poisonous vapors in order to repel mosquitoes out of the room. Next, you need to find out what voltage your battery is. It contains symbols for an LED, resistor, battery and a switch. A diode is connected across the relay for back EMF protection. In addition to being a switch, it can also be used to amplify electronic signals.

The output of transistor Q1 is given to transistor Q2. The collector and emitter terminals of this transistor are shorted and current flows from the DC power supply to the relay coil.

This circuit proves to be a relief in such situations. These symbols are graphic representations of the actual electronic components. The rate at which the lights are glowing depends on the RC time constant or clock frequency of the timer. Circuit Components Circuit Connection This electronic circuit consists of a crystal oscillator, two capacitors and a transistor forming a Colpitt oscillator.

The enable pin of the counter IC is grounded.

mini electronics project

A much advanced audio amplifier project is given below. Here is such an interesting project. Inside an LED there is an anode and cathode.

simple, low cost electronics projects

In this example, we will be using a 9V battery. These types of electronic projects are very simple and easy to be constructed and implemented.

Simple electronics projects for engineering students

The advantage of these over normal screwdrivers is the precision tips of each driver. So why not try your hands at charging a lead acid battery? A much advanced audio amplifier project is given below. It also provides sufficient time delay to the circuit. This causes the leakage current of the PNP transistor Q1 to increase. This will give you a voltage of 7 which needs to be divided by. The output of the operation depends upon the voltage drop across the diode. In other words the LEDs start glowing for each corresponding count. This timer IC is connected in mono stable mode with a resistor of 1M connected between pins 7 and 8. Circuit Components Circuit Connections The secondary of the transformer is connected to the diodes. Induction Heater Induction heater is a simple electronic project, which is easy to build with less number of components with less complexity. Timer IC is connected in the mono stable mode of operation. Bookmark this page, we will update the list of electronics projects frequently with latest electronics projects.
