Freedom KL26Z is an ultra-low-cost development platform for Kinetis L-series KL16 and KL26 MCUs based on Arm ® Cortex ® -M0+ processors.
Let’s see how to easily hack a remote control using ESP8266.
The Novato reference design (MAXREFDES16#) is a 16-bit, high-accuracy, loop-powered temperature transducer that transmits temperature information from a remote object to the central control unit over a 4–20mA current loop and using the highway addressable remote transducer (HART) communication protocol.
If you are away from home for a long time on a business trip, the goldfish at home will starve. Therefore, in order to prevent goldfish from starving when the owner is not at home, an automatic feeding robot was designed based on a 4-degree-of-freedom robotic arm and GD32E231. GD32E231 controls the robotic arm by generating PWM. At the same time, it picks up fish food from a fixed place and puts it into the fish tank according to the preset time. Through multiple manual trainings, the robotic arm automatically calculates the feeding based on the manual training data. eating position. At the same time, you can also add some auxiliary functions. You can roughly obtain the internal temperature of GD32E231 and the lighting conditions around the fish tank through the serial port or onboard ADC and photoresistor. You can turn on lighting equipment such as desk lamps when it is dark.
This application note demonstrates how to make a simple system that monitors temperature and analog voltages remotely. On meeting certain alarm conditions, the system can send SMS messages, which are then converted to email and forwarded to the designated email address.
Password locks are relatively common in life. There are various types of locks. The most common ones are in the form of numbers. Generally, you need to enter a few numbers to complete the password. This project uses color to complete the password lock. There are many types of colors, which are more complicated than numbers. Using color cards to set the password and unlock the lock is more difficult to crack, and it is relatively safer.
The Renesas Pet Activity Monitor is a practical reference design created in celebration of the Year of the Dog. This device can track your dog’s barking and activity, and data can be viewed and downloaded from your PC.
mini-violin is an open source project for violin design, and the circuit schematic is quite simple. The ATtiny85 controls two LEDs and a piezo buzzer, in addition to a button to switch songs. What's particularly interesting is that the violin strings are connected to the analog inputs of the microcontroller so that they can be controlled by contacting conductive materials. Come play the violin.
The Alameda (MAXREFDES24#) subsystem reference design features four dense, highly accurate analog outputs in a compact, galvanically isolated form factor. Each channel provides current or voltage. This design uniquely fits in programmable logic controllers (PLC), distributed control systems (DCS ), and other industrial applications. Hardware, firmware design files, and lab measurements are provided for rapid prototyping and development. The board is also available for purchase.
Just like piranha and mimosa, when your hand comes close to the petals, you can quickly close the 6 petals. It can be opened automatically after leaving~
Recently, Sebastian Staacks, a physicist and development engineer from Germany, created a unique electronic guestbook for his brother's wedding. The guestbook is developed based on the ESP32 Wi-Fi module. All wedding guests can log in to a simple web interface through their mobile phones, enter text messages and upload pictures. Affected by the COVID-19 epidemic, some friends cannot be present, but they can express their greetings and blessings to the couple remotely through this guestbook.
The 1/8 brick power module in this reference design is designed based on the 1/8 brick power supply standard defined by the Distributed Power Open Standards Alliance (DOSA). This power module uses an Analog Devices ADP1051 to control the energy conversion from input to output.
Smart charger design based on MAX1898 C program project file source code and circuit diagram
FRDM-KW40Z is a development platform for KW40Z/30Z/20Z Kinetis ® W MCU, supporting Bluetooth Low Energy and IEEE ® 802.15.4 for portable healthcare, wearable sports fitness and home automation devices.
Maxim Integrated's MAXREFDES79# reference design is a fully compliant IO-Link version 1.1, 4-port IO-Link Master using a TEConcept software stack. The system contains four IO-Link master transceivers, a standard ARM® Cortex® M3 processor, and efficient industrial step-down DC-DC converters. The MAXREFDES79# comes preprogrammed and ready to connect with any compliant IO-Link device using a simple-to-use graphical user interface (GUI) program. Design files including schematic, PCB, BOM, GUI software, and compliance report are available for download.
