Precision electronic scale design using 24-bit Σ-Δ ADC AD7791 and external zero-drift amplifier ADA4528-1
Bluetooth low energy expansion board based on the BlueNRG-M0 module for STM32 Nucleo
This is an original work by netizen jiezhi320 who participated in the RT-Thread application competition. In 2015, jiezhi320 made a version of hardware based on stm32f405rgt6. However, due to the high CPU usage of the UKF algorithm, the author migrated it to imx-rt1052, in order to leave enough resources for everyone to develop in-depth for model friends.
MSP430 car solution includes Protel and source code. It includes electric car seesaw, simple smart electric car, suspension motion control system, and automatic round-trip electric car.
There is a risk of electric shock and fire with this project! Light bulbs are essential devices in our lives. Incandescent and fluorescent light bulbs are typical light bulbs for household lighting fixtures. For industrial and public purposes such as street lighting, large indoor lighting, sports field lighting and any outdoor activities, apart from these bulbs, HID (High Intensity Discharge) lamps are also widely used. Typical HID lamps used for this purpose are high pressure sodium, metal halide, and mercury lamps. The last one has been banned in 2021 by the Minamata Convention on Mercury. Fixtures with incandescent and fluorescent bulbs, long used for home lighting, became obsolete within 10 years of the widespread adoption of LED lights, and currently offer only replacement bulbs. Low-wattage HID lamps are also gradually being replaced by LED lamps. High-wattage HID lamps still dominate the mainstream of large-scale lighting because the advantages of LED lamps at this level are smaller. Like many LED geeks, I built an LED fixture because it was rare, but when it became commonplace it stopped being fun. On the other hand, my nostalgia for the disappearance of glass tubes from our lives increased and I started collecting HID lamps as a light bulb geek. However, having only light bulbs makes no sense. In order to light a HID lamp, a lamp ballast rated for each bulb is required. Therefore, I designed and built an electronic HID ballast that can light a variety of HID lamps.
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.
The network card driver and LWIP protocol transplant program source code for the Ethernet communication module based on LPC2138 and DM9000AE written by myself.
The new SimpleLink™ multi-standard SensorTag kit helps you realize your Internet of Things (IoT) product ideas. The kit contains 10 low-power MEMS sensors in tiny packages that are expandable using DevPacks, making it easy to add your sensors or actuators. Connect to the cloud via Bluetooth® and get sensor data online in three minutes. SensorTag works right out of the box with iOS and Android apps, so no programming experience is required to get started. The new SensorTag is based on the CC2650 wireless microcontroller (MCU) and consumes 75% less power than previous Bluetooth products. Therefore, the SensorTag kit can be battery powered and a coin cell battery will last for many years. Bluetooth SensorTag contains iBeacon technology. As a result, your phone can launch apps and customize content based on SensorTag data and physical location. Additionally, SensorTag kits are enabled via ZigBee® and 6LoWPAN technologies.

S32K146 Evaluation Board
The QorIQ® T1024 Reference Design Board (T1024RDB) is a high-performance evaluation and development platform supporting the T1024 and T1014 communications processors.
S32K144 Evaluation Board
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 LS1024A-RDB is suitable for VoIP and video home gateways, security appliances, 802.11n enterprise access points and commercial network-attached storage products.
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.
