Additional 433.992 MHz radio remote control for GSM / SMS / RFID wireless anti-theft control unit. It has a button for perimeter activation, volumetric activation, SOS and deactivation. Power supply: 2 CR2016 batteries.
Set consisting of a stepper motor driver based on the ULN2003 chip and a 4-phase stepper motor. Equipped with 4 status LEDs for each phase of the motor, the driver is controlled via the 4 input pins IN1-IN2-IN3-IN4 with Arduino / Fishino or other microcontrollers. Power supply: 5 Vdc – 500 mA, driver dimensions…
This experimental board, made specifically for Arduino Mega, makes the connections of the PA0 ÷ 7 port of the Arduino Mega 2560 available and distributes them via on-board jumper for the management of the digital output lines. It also takes the signals from the PL0 ÷ 7 port of the Mega 2560 to manage the…
The set of commands of this remote is divided into two categories: the SMS ones and the DTMF tones. The former are simply summarized in the corresponding table, since they are the same as the ones described for remote 2 IN/2 OUT. Here we will only describe in detail the DTMF commands, first stating that…
This module uses the principle of optical LASER light scattering to measure the concentration of particulate matter (PM2.5 and PM10) in the air. It consists of a LASER diode, a photodiode, a microcontroller, a low-noise amplifier and a suction fan. The suctioned air passes through the detection chamber, where the LASER light striking the suspended…
Based on Arduino, it performs electronic light games by piloting a LED matrix thanks to a special multiplexing mode. In the “fast paced world” we live, moments when we can do whatever we want are rare and we have to cut them out from our routine, by skillfully balancing between the busy…
Stepper motor feedback controller able to dynamically check the positioning of the shaft and prevent any step loss in 3D printing, CNC, etc. It mounts directly on NEMA17 motors. All management of the controller is entrusted to Microchip’s programmed PIC32MX250F256HI / PT microcontroller; while the DRV8843 driver from Texas Instrument, driven directly by PWM pulses,…
