Using a DPDT 9v relay to control 2 LEDs.
The breadboard circuit, which consist of: 9v battery 2 led, red and green DPDT 9V relay, this relay is reverse polarity for the coil 330
Automatic night light using PNP transistor and photoresistor(LDR)
Below is the schematics diagram. The R1 controls the sensitivity of the circuit. If R1 is small, like 10k ohm, a little darkness will activate
IP Address – all you need to know 😀
Current there are 2 versions of IP address namely IPv4 and IPv6. The large number of devices that are connected to the internet today, makes
Hub, switch and router. What they are and their differences.
Ok let’s start with hub. Hub Belong to Layer 1 (Physical Layer) of the OSI model. Connects computers in a network and is a repeater
Using NPN transistor as a switch
The schematic for the circuit. Using Arduino Uno, 12v led strip, 9v battery and 2N3904 transistor, with some simple code to control on/off. And a
