Electronic circuit projects are inside the appliances around us. Normally, we do not need to understand their operation. But skill electronics have a lot of useful, three important things as follows.DC DC converters for Solar powered LED Lights.
2. Solar LED Garden Lights made with discrete components. * Schematics may differ slightly. CDS, on all circuits, is a photo resistor (light dependent resistor).LED TORCH CIRCUITS Talking Electronics
White LEDs have different "characteristic voltages." A 1,000mcd white LED used in this project had a characteristic voltage of 3.5v and a 3,000mcd white LED had a characteristic voltage of 3.2v.Water Powered Flashlight: 7 Steps (with Pictures)
What's A Joule Thief? A "joule thief" is a circuit that helps drive an LED light even though your power supply is running low. What can we do with it? We can use it to squeeze the life out of our drained batteries. Bottom line, this circuit makes LEDs glow even at low voltages.Light Emitting Diodes (LED) bcae1
Light Emitting Diodes. An LED is a special semiconductor which emits light when current is passed through it. There are many different physical styles.30 LED Projects Talking Electronics
A "Natural" or "Characteristic" voltage develops across a LED when it is correctly connected in a circuit with a current limiting resistor to allow a current between 1mA and 20mA.Simple electronic projects top 100 for you | ElecCircuit
Hi ElecCircuit, I love all your circuits and look forward to receiving them in the post. Perhaps in the new year you design a variable “voltage Current” 240V ac and say 1A power supply with panel meters as well, I cannot remember the make but the usa has one but it was for their voltage only “120V ac” (was the make sencore or something).HOW TO READ CIRCUIT DIAGRAMS: 4 Steps instructables
this instructable will show you exactly how to read all those confusing circuit diagrams and then how to assemble the circuits on a breadboard! for all the electronics hobbyist wannabes this is a MUST READ instructable. knowing how to read circuits is a very useful skill that will help you out all the time. especially if you start messing around with building little electronics projects.Joule Thief Single Cell LED Driver PRC68
Definition To be called a Joule Thief I think a circuit needs to be able to start when it's input voltage is below 1.0 Volt. That's because one volt is one of the definitions of a dead single cell battery.
