A while back, I noticed an ESP32 based Camera board called the ESP32-CAM on LCSC.com, and planned on getting one to play with but didn't get the chance until recently when I saw a tutorial by Rui Santos based on the board. I feel its a nice board and today's tutorial will focus on...

This high current forward-reverse DC motor driver is built using STK681-332 IC from ON Semiconductor. The circuit can drive brushed DC Motor with up to 12 A peak current. The circuit requires 3 input signals: Enable for PWM input for speed control, IN1 and IN2 to change the motor...

There are several situations where using an RTC could adversely affect your project by increasing cost, size, time accuracy or IO requirements. To prevent this, especially in ESP/WiFi-based or other clock-reliant projects, makers usually turn to obtain time information from NTP servers. I...

RFID based projects are one of the most popular Arduino projects out there and we have also built a couple of them here too, but I recently came across an RFID access control project by hwhardsoft that was built using the ArduiTouch MKR enclosures. The ready-made nature of the enclosures...

This is an analog input module that helps to digitalize temperature, current (4-20mA) and voltage (±10V) for PLC and Microcontrollers input. This analog module can be used for Programmable Logic Control (PLC), Programmable Automation Control (PAC) and Discrete Control System (DCS)....

The increased interest in IoT and electric automobiles around the world is driving an increase in the use of Lithium-Ion/Lithium-Polymer/NiCd/NiMH batteries as more devices and applications are using them, due to their high energy storage capacity to size ratio. This increased interest...

This is an Isolated gate driver-based N channel Mosfet Arduino Nano shield based on Si8261ACC, which can be used in various applications like DC Motor driver, solenoid driver, led driver, bulb driver and heater driver, with 3A fast switching diode provided across the output for an...

The module described here is an isolated CAN Transceiver module. This module can be used as a standalone module or as an Arduino Uno shield. A controller area network is a two-wire high-speed serial network typically used to provide data communication between host and nodes. The...
