Proximity Distance Sensor using DRV5053 Hall effect Sensor
This is a hall sensor proximity sensor that can detect magnetic targets approaching the sensor, without physical contact with the target. This sensor also can be used to detect the distance range 0-4cm (0-40mm). The target distance can be adjusted using the onboard trimmer...

Introduction to LoRa – Send data between two Arduino using LoRa
Selecting the right communication protocol is an important part of any IoT project as not being able to communicate with the server/device cloud quickly takes away the "I" in IoT and could lead to the ultimate failure of the project. Several communication protocols exist, from WiFi and...

Video Streaming Server on ESP32-CAM
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...

Network Clock using ESP8266 and OLED display
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...

Arduino RFID Reader using the ArduiTouch MKR Enclosure
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...
