Tolako Arduino Indicator Channel Official Review

Used this type on my CNC machine to allow the control panel to turn the router and dust collector on and off automatically. It works perfectly, I just turn on the computer and the relay turns the router/dust box on and off when the cut is done!

When I control the device with nodemcu, I can wake it up and let the built-in red LED light up, but there is no communication between the connection on the middle load side and the NC connection. I tried the first with a 115 volt connection, the second I just checked with an ohmmeter - there is no connection. I later realized that this is a 5V device and only 3.3V on the Nodemcu. Tested the relay with an Arduino Uno 5V and it works fine.

My entertainment center fans are on because my PS4 was overheating. The fans ran all the time, but I really didn't want them running all the time. I connected it to the USB cable and now the fans turn on from my PS4 which is great. I used the same USB cable for both power and signal, although the USB only runs on 5V it was able to provide power and close the relay.

I uh, so I've made that mistake before. But I could see the Hobbit getting completely frustrated for making a rookie mistake (which I still seem to be making, I blame all the software, not enough hardware). Don't think you can just connect 3 pins directly to Arduino pins. Sure you can turn on the light, but you don't have the power needed to drive the relay. After using the dedicated 5V and GND pins on the Arduino (I connected the Sig pin to pin 7) it worked like a charm.

This is a great product that meets my needs! I combined the module with a PIR sensor to power the lights in my shed. My shed is solar powered so I used an old USB lighter as the power source. I just removed the USB plug and connected the power cables. The module has three screw terminals for the output. I connected 12VDC to the center pin and one side of the bulb to the screw farthest from the diode. The module expects a positive voltage; ideal as most PIR sensors output +3.3 VDC when…

Ordered and delivered in 2 days via Prime. The packaging and everything else was excellent and it arrived in good condition. I just hooked it up to my circuit and tested it. I applied 5 volts to the positive and negative pins of the terminal, and when I apply 5 volts to input 1 (somewhat oddly labeled IPP ON (perhaps the input port is on?) I hear the coil inside the switch with a nice click I have a separate circuit that runs on 2.3V with a 330 ohm resistor and a small red LED This circuit goes

. It works with the Arduino Uno BUT it doesn't explain the trigger pins and for that reason I only gave it 3 stars. To make it work I had to tie the S and + input pins together, apply +5V to the two pins and ground to the - input pin. To get stable +5V with enough current I used pin 6 of analog PWM output. I added the following block of code to the void loop() section of my sketch: analogWrite(shutterRelayPin, 255);delay(delayPeriodTrip);analogWrite(shutterRelayPin…

Before you give your opinion. I wanted to share some information. I've read a lot of questions and reviews about this device and there seems to be a lot of confusion as to what exactly this relay board is and what it's for. I have been working in the electrical engineering trade for over 30 years. This is a very simple relay control board designed to drive a heavy load (110VAC, 12VDC, motor etc) at up to 10A although I wouldn't really try 10A on this board. This is NOT a power supply, it does…
