Remote Control

This is an 8 channel infra-red remote-control Arduino shield that can drive 8 high current loads such as LEDs, solenoids, multiple toy DC Motors, dual unipolar stepper motor, filament lamps, etc. Each channel consists of two parallel NPN transistors with freewheel diodes which are important to drive inductive loads like motors. The shield consists of 2 x ULN2803 Chips, Infrared receiver TSOP1838, trimmer potentiometer, 4 tactile switches with pull-down resistors. The shield is compatible with Arduino UNO. Arduino code is also provided to test the shield. I have used a cheap IR remote to test this shield, this remote transmit NEC code but any other remote can be used with this shield and it will require to decode the remote switches.

The board presented here is multipurpose hardware which includes the ESP32-Wroom module, 3.3V regulator, 5V relay, Power LED, Relay LED, and connector to program the ESP-32 Module. The project requires 5V_DC and consumes 60mA current when the relay is ON. The project can be used in IoT applications and the relay can be controlled using Bluetooth or WiFi. The hardware helps users develop single-channel relay-based projects. The relay can be controlled over Wi-Fi, and Bluetooth wireless communication using appropriate code. The relay is connected to the GPIO4 pin of the ESP32 module.

C115

This is an 8-channel remote in a compact board suitable for remote ON/OFF applications using Bluetooth or Wi-Fi protocol. The board consists of an ESP32 module and 8 tactile switches connected to various GPIO. The circuit works with 3.3V_DC power supply and a Li-Ion battery can be used to power the board. The onboard LED indicates the power. There is an onboard programming connector that helps users program the ESP32 module using Arduino IDE. The users have to write their own code to use the module, according to their requirements.

H102

The project described here is an 8 Channel RF remote transmitter This transmitter is built using LICAL-EDC-DS001 chip from LINX. The project consists of the Encoder/Decoder chip, a 433Mhz RF module as a wireless link, 8 x tactile switches for operations, 10 x jumpers to set the transmitter address.
