2 Channel Mini easy to use Relay shield for Arduino Nano consists of ULN2003 IC and 2 Mini 12V Relays with NO/NC contacts of 2A-24V Load Capacity. ULN2003 used as Relay coil driver. Relay can be controlled from D3 and D4 of Arduino Nano. Three-pin Header Connector CN1 and CN2 provided to connect the Load. Relay has normally open…
Light operated switch works with NE555 timer and light dependent resistor. It uses relay and toggle switch idea for operation.
Description: This is a basic breakout board for the FTDI FT232RL USB to serial IC. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 5V Arduino boards. It can also be used for general serial applications. The major difference with this board is that it brings out the…
LED Flasher is a simple project producing a flashing effect of six LED’s. This project can be used in all areas where you want to draw attention. Hi-glow LED’s providing enough flashing light to attract your attention. Can be used as warning light. SPECIFICATIONS Supply input 12 V @ 35 mA (6 to 15V Dc…
The project described here is a compact stereo volume and balance control with a rotary encoder. It provides 32 log potentiometer steps with buffered wiper output. The project can easily replace mechanical potentiometer. 5 LEDs indicate the volume level or balance settings , depending on the status of the mode indicator D1 LED. The MAX5440Â includes…
A Larger Digital Cricket Scoreboard for Better Visibility When spectators are positioned further from the boundary, a small scoreboard may not provide the visibility a club needs. Our 64 × 64 cm digital cricket scoreboard provides a larger display while remaining portable. The scoreboard consists of two main sections. The upper 64 × 16 cm…
This is a simple 4-in-1 do-it-yourself (DIY) kit from BuildCircuit. The kit has four different circuits that can be switched on separately or together at a time using a DIP switch. The four circuits are: 1. Dark sensor using LDR. 2. A latch circuit using NE555 timer. 3. Astable circuit using NE555 timer. 4. A…
VT-100 terminal emulator is a program for communicating with any serial device using a Bluetooth serial adapter. The RFCOMM/SPP protocol emulates serial communications over Bluetooth. You need a Bluetooth serial adapter.
As stated on the title, in this tutorial, we will rotate a motor in both directions. To achieve this, we can use a switch or the serial monitor. We will need an integrated circuit chip (IC), called H-Bridge, we will use a L293NE or SN754410 chip for our experiment.
 This USB/Wireless relay module allows computer to control switching of external devices by using the USB port of your computer. It has a wireless extension port, that can work with XBEE or Bluetooth Bee or Wifly modules, which means now you can control your device by Zigbee or Bluetooth or Wi-Fi. The TOSR0x module can be powered by USB…
Description: This circuit can be used for testing your TV, DVD, VCD, etc. remote control. This is the fundamental module for making infrared based object counter. This project has been derived from “Remote tester project” .
TSIR04B is similar to TSIR04. We have removed the OLED display and put the relay board in a plastic enclosure. This is a TSIR04B Wi-Fi version relay board with optically isolated inputs and temperature sensor port. You can easily control this relay board by your computer or smartphone using Wi-Fi. The communication method also can be changed easily. Replace…
