Introduction One of the bad things about electricity is that it is mostly invisible: unless the voltages or currents are very high, it mostly flows invisibly through wires, it’s existence only implied by a lighted up LED, a beeping speaker, an LCD that indicates something or another secondary effect. Normally, this is what we want:

DigiPot is a digital potentiometer using a rotary encoder as input along with a 7 segment display that show the current pot value. Description The “potentiometer” is actually a rotary encoder (TW-700198) connected to a microcontroller that reads the signal from it and convert it to a value that is displayed on 7-segment displays. The

So far, we’ve talked about the basics of SPI communication and UART communication, so now let’s go into the final protocol of this series, the Inter-Integrated Circuit, or I2C. You’ll probably find yourself using I2C if you ever build projects that use OLED displays, barometric pressure sensors, or gyroscope/accelerometer modules. I2C combines the best features of SPI and UARTs. With

Hi folks, now I’ll teach you how to make your programmer to the ESP-01 and ESP-201, (perhaps serve with other models) using an Arduino UNO, a few cables and optionally a button and a slide switch, in my case I use them because I had available, with this programmer able to upload the Arduino sketches

The PE42420 is a HaRP™ technology-enhanced absorptive 50 Ohm SPDT RF switch developed on the UltraCMOS® process technology. This general purpose switch is comprised of two RF ports and has very high isolation performance. It is ideal for RF and IF transceiver signal switching (signal amplitude adjust), discrete DSA stages, and filter bank switching applications.

When you connect a microcontroller to a sensor, display, or other module, do you ever think about how the two devices talk to each other? What exactly are they saying? How are they able to understand each other? Communication between electronics is like communication between humans. Both sides need to speak the same language. In electronics, these languages are called communication
