FastBond2 Phase 1 has received project submissions from many friends. Simple and easy, you can complete a Phase 1 project in just one day.
How simple is it? You can submit a project just by drawing a block diagram with Scheme-it; how easy is it? You can freely express ideas that you wanted to implement but haven’t yet, regardless of right or wrong. You have ideas, and we have a platform for you to express them freely, along with monetary rewards.
Based on this, a simple smart Bluetooth lamp scheme was born. Let’s take a look at the specific introduction of the scheme. Click the link to learn more about the project: (Smart Lamp)

Project Introduction
The lamp is a very common and convenient household appliance. The one I currently use has touch control and is rechargeable. I want to take this opportunity with FastBond2 to design a new Bluetooth lamp, featuring:
-
Bluetooth technology to create a lamp that can be controlled via a mobile phone, such as turning on/off and adjusting brightness.
-
Human infrared sensing control, making it convenient at night when your hand is close to the lamp.
-
Adding MP3 music playback. You can play, pause, or set a timer for song playback via Bluetooth.
-
Adding a microphone to use Espressif’s Skainet component to achieve voice control of lamp brightness.
Here is the specific introduction to the scheme block diagram:
The scheme block diagram is designed using the convenient Scheme-it!! I will need to take a good look at it for more projects!
To implement this scheme, the following components will be used:
1. Main Control Chip: ESP32-S3
The ESP32-S3 chip has industry-leading low power consumption and RF performance, supporting WiFi IEEE802.11b/g/n protocols and Bluetooth 5. This chip is equipped with a dual-core Xtensa-R32 LX7 processor, with a working frequency of up to 240 MHz. It supports secondary development without needing other microcontrollers or processors. The chip has 512 KB SRAM, 384 KB ROM, and 16KB RTC SRAM. The chip supports multiple low-power operating states, meeting the power consumption needs of various application scenarios. The chip’s unique fine clock gating function, dynamic voltage clock frequency adjustment function, and adjustable RF output power function can achieve the best balance between communication distance, communication rate, and power consumption.
2. Audio Codec: MAX98357
MAX98357A/MAX98357B are digital pulse code modulation (PCM) input class D power amplifiers that provide AB class audio performance while having the efficiency of class D. The device can provide 5 selectable gains (3dB, 6dB, 9dB, 12dB, 15dB) through a single gain setting input in I2S/left-aligned mode, with a fixed 12dB gain in TDM mode.
3. Ambient Light and Infrared Proximity Detection Sensor: MAX44000
MAX44000 integrates a wide dynamic range ambient light sensor and an infrared proximity detection sensor, making it an ideal solution for portable touch screen control products. In ambient light detection + proximity detection applications, the IC consumes only 11μA (time average) current (including external IR LED current).
This is the introduction to the smart Bluetooth lamp scheme.Through this FastBond2 Phase 1, I thought of such a multifunctional lamp that can play music, be voice-operated, and controlled via Bluetooth.I hope to have time to improve the circuit diagram later and learn KiCad to truly carry out the project.

Join FastBond
The FastBond2 Phase 1 project is completed like this. Isn’t it super simple? Spending 2 hours in the evening playing games, and the project is done, with corresponding rewards coming soon.
Let’s take a look at the steps to participate in Phase 1:
1. Click “Sign Up” on the competition homepage;
2. Open Scheme-it to register an account and draw the scheme block diagram;
3. Record a video of about 3 minutes;
4. Publish the Phase 1 project in the Electronic Forest;
The four steps of Phase 1 are achieved. As long as you have a scheme (no limit on difficulty, no limit on right or wrong), we have rewards, and!!! You can also change accounts and information to participate multiple times. What are you waiting for?
Come and save the competition homepage: https://www.eetree.cn/page/digikey-fastbond, and sign up for the competition. The deadline for participation is October 15, and the Phase 1 rewards are monthly. The earlier you submit, the earlier you get the rewards.
