2 Relay module

This is a 5V, 10A 2-Channel Relay interface board. It can be used to control various appliances, and other equipments with large current. It can be controlled directly with 3.3V or 5V logic signals from a microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).

It has a 1x4 (2.54mm pitch) pin header for connecting power (5V and 0V), and for controlling the 2 relays. The pins are marked on the PCB:

  • GND - Connect 0V to this pin.
  • IN1 - Controls relay 1, active Low! Relay will turn on when this input goes below about 2.0V
  • IN2 - Controls relay 2, active Low! Relay will turn on when this input goes below about 2.0V
  • VCC - Connect 5V to this pin. Is used to power the opto couplers

36 in one Arduino Sensor kit

This is an Arduino sensor learning kit developed by Keyestudio. We bring together 36 basic sensors and modules, aiming for the convenience of its learning for starters. Inside this box, there are digital and analog sensors and also some special modules such as ultrasonic, bluetooth,, acceleration modules etc. For each module, there is clear connection diagram and sample code. So even if you are totally new at this, you can get started easily. The sample codes for this sensor kit are based on ARDUINO because it's open source and easy. And if you are good at this, you can also apply this kit to other MCU development platform, such as 51, STM32, Raspberries Pi. The working principle is pretty much the same. Now, let us embrace this fascinating world of ARDUINO and learn together!
