Building a reliable power supply is essential for any electronics project, especially when working with breadboards and microcontrollers like Arduino or ESP32. This guide walks you through a 5V/3.3V adjustable regulated power supply built using an …
When embarking on an electronics project, choosing the right components is crucial for ensuring efficiency and functionality. Voltage regulators are integral parts of many circuits, particularly when dealing with microcontrollers like Arduino or pow…
Here in this tutorial we will build a automatic overcharge cut-off Lithium Polymer Battery Charger or LiPo battery charger. This LiPo battery charger could be useful to those who uses lithium polymer battery for robotics, motors, quad copter etc. An…
12V regulated power supplies is regularly needed for various electronics circuit testing. I have been trying to drive a Nema17 stepper motor using A4988 stepper motor driver and series of lithium ion batteries. I don't know why but the stepper …
Recently I build two wheels WiFi control Arduino Car which uses 4 cell 1.2V battery pack to power the car. The total voltage will be 4.8V. When I build the Bluetooth controlled Arduino car , I found that building a rechargeable charger on the car w…
