A PWM-controlled regulator, this time using a logic gate IC, op-amp, and resistors and capacitors to buffer the PWM signal.

One of the most basic electrical circuits is the resistor-capacitor circuit driven by a DC power supply, as shown in Figure 1. A step further than the circuit in Fig. 1 is the circuit show in Figure 2 ...

Figure 1 gives a simple circuit for the PUSH ON, PUSH OFF function with only a few inexpensive components. In this design, the output is connected to the input of the gadget when you press the push ...

So, whether a given designer or engineer is attempting to determine the voltage, resistance, or current value they will need for a particular installation, or perhaps optimising LED circuits with a ...

Here’s a simple FET circuit that lets you switch ... t being actively pulled into any direction. See the R1 resistor in the intro circuit? It keeps the gate discharged and the FET closed unless ...

The ESP8266 is the reigning WiFi wonderchip, quickly securing its reputation as the go-to platform for an entire ecosystem of wireless devices. There’s nothing that beats the ESP8266 on a ...
