Replicating an EGS002 Equivalent Board using Arduino
The EGS002 board is nothing but a combination of a microcontroller with a H-bridge driver like the IR2110. So if you are interested to build your own EGS002 equivalent board with exactly identical features, then you can do it using the instructions given in the following article. So, here we are trying to build our […]
BQ24295 Smart Battery Charger IC with Boost + OTG
This BQ24295 IC is like a super smart charger chip. This one is not just for charging battery, but also doing many other jobs like boost converter, USB detection, power path control, and even OTG (host power supply). So we can say that this is a full battery charging and power management IC. Let us […]
INA219 Current Sensor Circuit Diagram and Datasheet
In this post we are going to understand this sensor called INA219, and this one is like a full smart sensor. It not only tells how much current is flowing but also tells voltage, and also calculates power, all in digital form. That means it talks with microcontroller through I2C lines. It is like an […]
ACS712 Current Sensor Circuit Diagrams and Datasheet
Here we are going to learn one cool and very important current sensor device which we call ACS712. This small chip that look just like a normal 8-pin IC, is actually able to sense current from any load and give us a proportional analog voltage output which we can easily feed to Arduino or any […]
True MPPT Solar Controller Circuit using IC 555
Are you wondering if it was possible to build a very simple MPPT circuit using ordinary parts like IC 555 and IC 741, which would work most efficiently imitating a true MPPT? The answer is yes, it is possible, and we will learn about it details, in the following article. In this design I used […]
