In this article I will explain how we can build an Arduino-controlled H-Bridge sine wave inverter circuit using some easy parts. So this thing will basically convert DC into AC but in a way that looks like a sine wave, right? We are using an Arduino to generate PWM signals and these signals will drive […]
Newly Updated Circuit Projects:
Real MPPT Solar Charger Circuit Using Arduino, LCD, and Manual/Auto Switch
So in this article we are trying to make a true MPPT solar charger project using Arduino which will charge a 12V battery from a solar panel and will use MPPT logic to always extract maximum power from the solar panel. That means that even when sunlight changes, we try to adjust PWM duty cycle […]
Simple Low Dropout Regulator Circuits Explained
The transistorized low dropout voltage regulator circuit ideas explained in the following article can be used for getting stabilized output voltages right from 3 V and above, such as 5 V, 8 V, 9 V, 12 V, etc with an extremely low dropout of 0.1 V. For example, if you make the proposed 5 V […]
Adding a Soft Start to Water Pump Motors – Reducing Relay Burning Problems
In this post I have explained a few innovating and simple soft start circuit examples which may be implemented with heavy duty motors so that they are able to initiate with a soft start or a slow sluggish start instead of a sudden, bumpy start Why Soft Start is Crucial for Heavy Motors When heavy […]
