In this tutorial, we will make Lora Transmitter & Receiver using Lora Module SX1278 & ESP32 Wifi Module. The communication type is a point to… Arduino Projects How to use Reyax RYLR890 LoRa Module with Arduino Mamtaz AlamUpdated:August 21, 202285 Mins Read9K ...
A relay transistor driver circuit can be considered a great example of a boost converter circuit. The flyback diode connected across the relay is introduced to short circuit the reverse back EMFs from the relay coil and to protect the transistor whenever it switches OFF. If this diode is remov...
It is really important for us to ensure that the voltage rating of the relay coil matches up with the rectified DC voltage we calculated earlier. So if our rectified voltage is sitting at 309.2V then we need to make sure to use a relay that can handle that specific voltage. Relay Switchi...
I useI2C 16x2 Arduino LCD Display Module. Water level balance test This problem needs to be explained separately. Although we have realized automation of water draining and supply, we cannot keep the water level balance under this automation, because water draining and supply speeds are different....
Identify the hot power wire (red wire in the diagram above) in the cord leading to the light bulb and make a cut. Connect the side leading to the light bulb to the NO terminal of the relay, and the side leading to the plug to the C terminal. This way the relay is on the hot ...
To check the relay on the circuit board, attach one lead to the connection after the relay that leads to the blower motor and the other to a ground. With the thermostat on, this should have the same reading as the above test. This will determine if the power is making it past the re...

4S just means four 3.2V cells in series to make a 12V nominal pack. The pack/bank is really closer to a 13.3V pack as the resting & nominally loaded cruising voltage of these cells is around 13.2V – 13.35V. If you want to do other than a 4S configuration the cells are typically ...
Your local mechanic or any small repair shop should be able to diagnose the problem. Of course, the quickest way is to make an appointment with your dealer. Many dealers have the part in stock. The blower motor resistor or control module replacement is not very expensive. For...
designing a new control system for it challenging. I looked for ways to modify or automate the original control box, but couldn't figure out a way to make it work. So I gave up on trying to use the old control box, stripped it of usable parts, and started designing something ...
