It can be controlled through logic levels to set the speed and the direction of the rotation of CC brushed motors and stepper motors; outputs have LEDs indicating the rotation direction. The circuit board we are presenting this time is based on the dual-bridge driver L298N, in a traditionally mounted version in a Multiwatt container with 15 staggered pins; it has two terminal blocks for attaching to DC moto ...

Researchers have demonstrated the high-performance potential of an experimental transistor made of a semiconductor called beta gallium oxide, which could bring new ultra-efficient switches for applications such as the power grid, military ships and aircraft. The semiconductor is promising for next-generation “power electronics,” or devices needed to control the flow of electrical energy in circuits. Such a ...

The PNP transistor is a mystery to many. But it doesn’t have to be. If you want to design circuits with transistors, it’s really worth knowing about this type of transistor. For example: Want to automatically turn on a light when it gets dark? The PNP transistor will make this easy for you. In my article how transistors work, I explained how a standard NPN transistor works. If you haven’t already, I’d reall ...

If you have high-powered LEDS, or a power supply, or are trying to control larger motors, you have to get a lot of heat out of your circuit boards. The classic way to dissipate heat is to bolt your power transistor to an aluminum heat sink. That is a slow, messy, and expensive proposition, especially if you need thermal grease between the transistor and heat sink (Figure 1). Another problem with bolted-up h ...

A well known power supply circuit is the capacitance multiplier. It doesn't regulate, but instead reduces ripple & noise while the output tracks at some fraction of the input voltage. The R1/R2 voltage divider determines VOUT (a VBE below VB), and must be chosen to account for the maximum ripple on the minimum VIN. If VIN is regulated, the circuit can be used purely for low-level noise reduction. In thi ...

AIM To control a relay switch using esp8266 in standalone mode(without arduino,pic or any other Micro-controller) via Web-UI The ESP broadcasts its own SSID.It does not connect to a router.local IP address of esp is 192.168.4.1 Step 1: Gather Hardware ESP 8266 (There are a lot of variants available in the market.for this tutorial lets just use the esp-01).If you are curious about the different variants clic ...

DC Output Solid State Relay 10Amps 60V DC (Optically Isolated Input) This project has been designed around TLP250/352 which is Opto-Coupler IGBT/MOSFET Gate Driver from Toshiba and Mosfet IRFP260 from IR, This relay consists of optically isolated gate driver and low impedance Mosfet. The combination of low resistance and high load current handling capabilities make this Relay suitable for a variety of switc ...

Among my recent electronics purchase spree was the amazing Teensy LC from PJRC. It has a nice ARM Cortex-M0+ processor, real hardware USB, and what’s the nicest part, an Arduino add-on called Teensyduino which enables easy programming with Arduino, but with support for many of the hardware features. Now I started playing piano a while ago, and just a few weeks ago bought a Pianoteq license to send notes via ...

It’s been a while since I posted a new article, a delay at least partly due to me herniating a disc in my neck which left me completely unable to look downwards for any length of time and as you’ll know all too well you can’t work on circuit boards without peering down at them. Look after your neck and back folks, and I mean that seriously. Well I’m back now and I’ve got a lot of ideas for articles spinning ...

Up until now, we have talked about working with a lot of low-power devices. Sensors, LEDs, ICs, and the like are all capable of being powered directly from your Arduino, but as many awesome 5 and 3.3v components as there are, eventually you will find yourself holding a 12v solenoid, motor, or light and wondering “How the heck am I supposed to control this from my Arduino?” Well today we are going to talk ab ...
