The Arduino TCS3200 sensor is a reliable currency detector that accurately detects and identifies various currencies based on their unique color patterns, making it an essential tool for automated ...

Metal Detector is a security device which is used for detecting metals which can be harmful, at various places like Airports, shopping malls, cinemas, etc. Previously we have made a very simple Metal ...

Calibrate the sensors to ensure accurate readings. This involves setting baseline values for both the accelerometer (zero-point calibration) and soil moisture sensor (dry and wet calibration).

Arduino Code for Interfacing MQ-5 Gas Sensor Module. The Arduino MQ-5 gas sensor module's coding is straightforward. We're simply reading the Sensor's analog data and turning the LED and Buzzer ON or ...

The TB-007 smart robot is equipped with a metal detector and is based in an Arduino with a motor shield which has the ability to control the two main motors, including a stepper motor and three servos ...

This research study presents the design and implementation of a Metal Detector Robot equipped with a bomb detection capability, utilizing various technologies including the Arduino development board, ...

Chipped radio-frequency identification (RFID) sensor systems have been studied for structural health monitoring (SHM) applications. However, the use of chip in sensor tags and its standardized ...

This remote-controlled metal detecting Arduino-powered robot is legit. If the video player is not working, you can click on this alternative video link . Everyone loves metal detecting.

Arduino ADC is usable around 10/12 bits. That means it can measure up to 1024/4096 diferent voltage levels. Counting frequency instead can let you choose your own diferent measurement levels ...

There are other metal detector projects using AVR and PIC. This one is nice and simple. I do wonder why the 7.64khz frequency was chosen instead of something in the 15k to 20k range wasn’t used.
