Here we have provided PCB layout, circuit diagram, and Gerber files so that you can build or directly order this Relay Driver Module. Previously we have built 4-channel Relay Driver Module, but this ...

Features: Hardware components: Arduino, relay module, jumper wires, and external power source Code: Arduino code for controlling the relay based on sensor input or a manual switch Applications: Home ...

Circuit Diagram The circuit diagram and schematic for Arduino Power Supply Shield is pretty simple and doesn’t contain much component placement. We will be using 12V DC Barrel Jack for main voltage ...

In the transmitter LoRa circuit, I have used Arduino Nano. I have made a voltage divider using 4.7k and 10k resistors to drop down the 5-volt logic level to the 3.3-volt logic level. The pushbuttons ...

The shield kit won't be cheap when it arrives on May 2nd for $60, but it may prove the real bargain for tinkerers who want a full-fledged Arduino board as soon as the training wheels come off.
