Relays are frequently used in our electronics applications specially when we need to drive high loads from microcontroller circuits. If you want to latch it with two high pulses, then using a 555 timer is bistable mode will help. Relays are used where it is necessary to control a circuit by a separate low-power signal, or where several circuits must be controlled by one signal. We have previously used EasyEDA many times and found it very convenient to use compared to other PCB fabricators. Relays are most commonly used switching device in electronics. In most Arduinos the power will be 5V, in a Raspberry Pi it will be 3.3V - but these relay modules will work OK with 3.3V even though they are officially rated at 5V. In-here we have designed an isolated PCB for 4 relays to operate 4 AC appliances at a time. Relay Contact Ratings: Figure 3. You can use a relay module to control the AC mains and Arduino to control the relay. The one you use will depend on whether you want the 5V signal to turn the switch on or turn the switch off.
