How to Soldering is Easy
Friends say that Electronic Project I presented is not working. But any project in The Our Electronics Projects Tested through the creation of me. Therefore guarantee that the It certainly worked. When I was a beginner. Most projects do not work because my solder joint is bad. As Figure below. It may cause an electric current does not flow through the circuit devices. Or sometimes, I soldered too much until a short circuit. These are all the reasons the project is not working. Good soldering requires great skill. Experience and Which has How to as follows. 1.You should bend slightly …
How to basic use LEDs
My son is very interested in the LED. He want to created the simple LED flasher circuit. But we should learn the principles of the LED before. Started to use the LED circuit as Figure 1. Includes Battery, Resistor and LED – Its shape – symbols (When drawing the circuit, if the actual shape it waste so much time, symbols should be used) Things should remember The battery and LED are polarity must be used correctly. Next Step… How much voltage’s LED? I recommend breadboard because it does not require electric soldering iron. Perfect for my son. He experimented to …
How to make a simple series circuit
Today, my son experiment on the simple series circuit. To understand current flow and voltage across all devices in the circuit. Parts he will needs 1. R2____1K 0.25 watts resistors 2. R1____100 ohms 0.25 watts resistors 3. the power supply 4. the breadboard 6. the digital multimeters 7. Wire jumpers How to experiment First of all, he builds the simple series circuit by using one resistor as Figure 1. He installed all resistors into the breadboard. Then, apply the 10V power supply to the resistor as a complete circuit. Figure 1 the simple electronic circuit Then, he measures a current …
