I would expect something more like 100 to 200 ohms (assuming the Wemos pins can handle the current). Without a diode in this position you'll simply instantly fry the transistor the first time it switches off due to the inductive kick-back - the diode tames this.Ī 2N2222 might or might not be able to handle the current of this relay, but note the base current needs to be at least 5% of the load current for it to switch fully - you need to find out the Wemos board's pin current handling ability to judge this.Ģ.1k resistor does sound rather high though, that's only 1.4mA from a 3.3V drive voltage (3.3V - 0.6V) / 2100 = 0.0014. You'll see an 1N4007 diode in that circuit. Secondly when switching a relay you must have a free-wheel diode across the relay coil, as in this tutorial:

So you need to measure the resistance of the relay coil and figure out the current it needs (I = V/R). This means the coil will be powerful and take a lot of current - but I can't find any proper data for it. I am stupid.įirstly the RF6105-12V-C relay seems to be a high power contactor, switching 150A. The relay is controlling a 12v linear actuator. I want the relay to engage when the pin d1 goes high. The relay engages when I get 0v or ground going to the point that the 'collector' is going to in the diagram. Did I wire them up correctly? Is my resistor too large/small? I assume the transistors went bad or I shorted them out when mounting it. I have confirmed that the relays are still good, but I can't get it to work with the transistors. I mounted the actuator and it stopped working. I was able to engage the linear actuator via 3.3v from wemos board - transistor - relay several times without any problems. I had two of the transistors with a 2.1K resistor switching two separate relays and it worked. I didn't have any TIP120's on hand, so yesterday I thought I would try the 2n2222 to do the exact same thing. I did this same exact thing on another project, but I used a TIP120 transistor with a 2.1K resistor and arduino uno to do the switching, and it is still in use now. I am trying to switch a rf6105-12v-c (what I am calling a relay?) with a 2n2222 transistor. The grapefruit juice will keep you going for hours in a healthy way.I have read many threads about using transistors to switch relays of larger voltages on with microcontrollers, but most of them end without a solution, or I am not smart enough to understand the responses given. Recharge with grapefruit juice after you exercise and you won’t feel the after-workout-energy-slump an hour later.

The juice is full of antioxidants that will help your body repair damaged soft tissue and muscle and your body will use the vitamins and minerals in the juice for fuel. But baking it will bring out the natural sweetness in the fruit and you may not need to add sugar.ĭrink the juice after a workout – Give your workout a boost by drinking white grapefruit juice afterward instead of water. If it is a little too tart for you, then you can add brown sugar to sweeten it. Just slice a white grapefruit in half, place it flesh side up on a baking sheet and bake it in the oven until it is soft. Eating fiber for breakfast will help you feel full until lunchtime. Baked grapefruit is a healthy breakfast that has less than 100 calories and lots of healthy fiber. If you want to spice up your routine a little, you can add pink or Ruby Red grapefruit slices to the white grapefruit and mix up flavors.īake it for breakfast – White grapefruit has the perfect texture for baking. The fruit will infuse the water with vitamins and minerals and it will make it taste refreshingly great. You can get a lot of the benefits associated with eating grapefruit by slicing white grapefruit and adding the slices to water either in a pitcher or in a travel mug. Plain water just doesn’t appeal to everyone. Slice grapefruit and add it to water – Fresh fruit infused water are one of the hottest healthy eating trend, as people are trying to give up unhealthy sodas and drinks filled with sugar.
