There is an in-built equalizer in Tinysine Bluetooth 5.0 module. If you have the CSR USB-SPI programmer, you can change the equalizer settings by yourself. TSA6175 module uses the CSR8675 Bluetooth chip. It needs a new version software to change the EQ settings. This tutorial will teach you how to set it. Hardware and Software required: Tag-Connect…
The range of a Wi-Fi signal can be influenced by several factors, which can impact its coverage and strength. Understanding these factors can help you optimize your Wi-Fi network for better performance. Here are the key factors that affect Wi-Fi transmission range: Frequency Band: Wi-Fi operates in different frequency bands, such as 2.4 GHz and…
This tutorial gives extremely simple easy for changing the baud rate of your BlueSMiRF Gold/silver bluetooth module. In this article, I have presented the baud rate changing steps done on Windows 7.
This is a 2 x 50W audio amplifier board with AudioB plus Bluetooth module. It has a perfect class-D architecture (based on TPA3116D2) and every channel has 50W power output. Both channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC 10V-24V power supply, it can be used to drive…
Description: In the monostable mode, the 555 works as a “one-shot” pulse generator.  Other applications of monostable mode include timers, pulse-width modulation (PWM), missing pulse detection,  touch switches, frequency divider, capacitance measurement, bouncefree switches  and so on.Â
This is yet another multivibrator kit. A similar kit article has been published recently. You can see it here.
Description: This is a basic breakout board for the FTDI FT232RL USB to serial IC. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 5V Arduino boards. It can also be used for general serial applications. The major difference with this board is that it brings out the…
Tutorial for Amarino Beginners- Display your SMS on 16×2 LCD. This tutorial shows you how to display SMS on 16×2 LCD. This tutorial is based on Amarino. It utilizes Receive SMS plugin of Amarino. This plugin sends the first 30 characters of a received SMS to Arduino. The message is sent as a string. The…
In this tutorial, we will learn to connect and use the RTC (Real Time Clock) module to display date and time on the 16×2 LCD display. DS1307 is called the Maxim-Dallas module for Arduino with which it allows us to have a precise system clock.
This Arduino shield helps to drive various loads like a solenoid, valve, motor, inductive actuator, heater, and bulb. A wide supply range 8V-60V and a load current of 2.7A allows it to be used with a variety of actuators. The board can be used as a stand-alone driver or it can be controlled by Arduino…
I was testing a couple of low-cost laser diodes that come from china and I was wondering why those diodes don’t have any protection/driver circuitry. Those diodes come with a simple series resistor for current control which is not a good idea nor stable.
The LM317 is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5 A over an output-voltage range of 1.25 V to 37 V. It is exceptionally easy to use and requires only two external resistors to set the output voltage. Furthermore, both line and load regulation are better than standard fixed regulators.
